Answers
Answer:
a) [tex]c=\frac{-1+\sqrt{13}}{2}[/tex] and [tex]c=\frac{-1-\sqrt{13}}{2}[/tex]
Step-by-step explanation:
The idea for the solution of this equation is to find the value of c where both parts of the piecewise-defined function are the same. So we need to take the parts of the function and set them equal to each other, so we get:
[tex]3-x^{2}=x[/tex]
and then solve for x. We move everything to one side of the equation so we get:
[tex]x^{2}+x-3=0[/tex]
and we use the quadratic formula:
[tex]x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]
and we substitute:
[tex]x=\frac{-1\pm \sqrt{(1)^2-4(1)(-3)}}{2(1)}[/tex]
and solve
[tex]x=\frac{-1\pm \sqrt{1+12}}{2}[/tex]
[tex]x=\frac{-1\pm \sqrt{13}}{2}[/tex]
so our two answers are:
a) [tex]c=\frac{-1+\sqrt{13}}{2}[/tex] and [tex]c=\frac{-1-\sqrt{13}}{2}[/tex]

a straight line is 180 degrees. angle 8 is 23 degrees. we want to know the rest of the angles measures. 180-23=157. angles directly across the vertex are the same measure. and since the lines are parallel 2,4,6,and 8 all have the same measure and 1,3,5,and 7 have the same measure.

A triangle has a base of 3 feet and an area of 15 square feet. Find the triangle's height
Answers
Answer:
10 ft
Step-by-step explanation:
The formula for the area of a triangle can be used. Put the known values into the formula and solve for the unknown.
A = (1/2)bh
15 = (1/2)(3)h
h = 15/1.5 = 10
The triangle's height is 10 feet.
Answer:
10
Step-by-step explanation:
A=1/2*b*h
15=1/2*3*h
15=3/2*h
15=3/2h
h=15/(3/2)
h=(15/1)(2/3)
h=30/3
simplify
h=10
Find the distance from the point (0, 4, 3) to the plane 5x +1y +2z
Answers
Answer:
distance =
[tex] \sqrt{ \frac{10}{3} } [/tex]
Step-by-step explanation:
Without going through and deriving this (my blackboard doesn't have space and a textbook, teacher, or online tutorial is probably better for that), the equation for the distance from some point on the plane to some point in space is as follows:
[tex]distance = \frac{ax + by + cz - d }{ \sqrt{ {a}^{2} + {b}^{2} + {c}^{2} } } [/tex]
•Note that the d in the equation should actually be D but Brainly doesn't allow me to do uppercase letters on mobile it seems... Anyway, d in the equation represents the value which the equation of the plane is equal to. You only gave the plane equation so I assumed d=0 in my calculations.
•x, y, and z all come from the point which you want to find the distance to. So (x,y,z)=(0,4,3) here.
•a, b, and c all come from the components of the vector normal to the surface. For planes, it simply somes to be the coefficients in front of each part. So (a,b,c)=(5,1,2) here.
With that you just need to plug the information in and simplify for your answer. My work is in the attachment, comment with questions or if anything seems off.

An isosceles triangle has vertices at (1,1) and (3, 3). Which of the following could be
the coordinates of the third vertex?
A. (2.1)
B. (3.2)
C. (4,1)
D. (5,1)
Choose
Answers
Answer:
D. (5,1)
Step-by-step explanation:
Because it is an isosceles triangle, the next point we choose must result in two sides with the same length. This means that either the two new sides are equal, or that one of the new sides is equal to the original side. If we wanted both of the new sides to be equal, they would have to be equal distance from the new point and one of the points of the original line. However, none of the options result in both new lines being the same length.
(2,1) would result in one new length being 1 unit long (2-1 x-coordinates) and the other being square root 5 (distance from point 2,1 to point 3,3 minus both coordinates and use Pythagoras). Points 3,2 and 4,1 yield the same result: Length 1=1 unit length 2=square root 5. Length 1 = 3 unit, length 2 = square root 5.
Therefore we are looking for a point which instead yields one length which is the same length as the original. The original length was 2^2 + 2^2 = c^2 = square root 8.
If we try the point 5,1 then we get two lengths of 4 and square root 8, it forms a isosceles triangle whose base line is parallel to the x-axis.
Sorry is my explanation was confusing, it's much easier to try and draw it on a grid and visualize it. Basically the overall idea is to test the side values you get by finding the distance between the points and going with the option which results in two sides with the same length.
Hope this helped!

Answers
Answer:
x = 12
Step-by-step explanation:
Given that AB = 2, AD = x, BC = 2, CD = -16 + 2x, since A, B, C, D are said to be collinear, therefore:
AB + BC + CD = AD
2 + 2 + (-16 + 2x) = x
Use this equation to solve for x
2 + 2 - 16 + 2x = x
-12 + 2x = x
Subtract 2x from both sides
-12 + 2x - 2x = x - 2x
-12 = -x
Divide both sides by -1
[tex] \frac{-12}{-1} = \frac{-x}{-1} [/tex]
12 = x (negative cancels negative)

The supplement of an angle is 42 degrees less than 3 times the complement of the angle. What is the measure of the angle?
Answers
Answer: 24°
Step-by-step explanation:
Given the following :
supplement of an angle is 42 degrees less than 3 times the complement of the angle
Let the angle = θ
Supplement of angle = 180° - θ
Complement of angle = 90° - θ
Supplement of angle is also said to be:
(3 × complement) - 42° = 3(90° - θ) - 42°
= 270° - 3θ - 42° = 228° - 3θ
Hence,
180° - θ = 228° - 3θ
Solve for θ
-θ + 3θ = 228° - 180°
2θ = 48°
θ = 48°/2
θ = 24°
How do you breakdown the quotient for 814÷3.7
Answers
Answer:
move the decimal to the end and add a zero to 814 i think
Step-by-step explanation:
Put 487, the dividend, on the inside of the bracket. The dividend is the number you're dividing.
Put 32, the divisor, on the outside of the bracket. The divisor is the number you're dividing by.
step 1 divide dividend by divisor in long division 487 divided by 32 Divide the first number of the dividend, 4 by the divisor, 32.
4 divided by 32 is 0, with a remainder of 4. You can ignore the remainder for now.
step 2 subtraction in long division problem 487 divided by 32 Put the 0 on top of the division bracket.
This is the beginning of the quotient answer.
Next, multiply 0 by the divisor 32 and insert the result 0 below the first number of the dividend inside the bracket.
0 * 32 = 0
step 3 long division 487 divided by 32 Draw a line under the 0 and subtract 0 from 4.
4 - 0 = 4
step 4 long division 487 divided by 32 Bring down the next number of the dividend and insert it after the 4 so you have 48.
step 5 long division 487 divided by 32 Divide 48 by the divisor, 32. The answer is 1. You can ignore the remainder for now.
48 ÷ 32 = 1
Note that you could skip all of the previous steps with zeros and jump straight to this step. You just need to realize how many digits in the dividend you need to skip over to get your first non-zero value in the quotient answer. In this case you could divide 32 into 48 straight away.
step 6 long division 487 divided by 32 Put the 1 on top of the division bar, to the right of the 0. Next, multiply 1 by 32 and write the answer under 48.
1 * 32 = 32
step 7 long division 487 divided by 32 Draw a line and subtract 32 from 48.
48 - 32 = 16
step 8 long division 487 divided by 32 Bring down the next number from the dividend and insert it after the 16 so you have 167.
step 9 long division 487 divided by 32 Divide 167 by the 32. See a pattern emerging?
167 ÷ 32 is 5 with a remainder of 7
step 10 long division 487 divided by 32 Put the 5 on top of the division bar, to the right of the 1. Multiply 5 by 32 and write the answer under 167.
5 * 32 = 160
step 11 long division 487 divided by 32 Draw a line and subtract 160 from 167.
167 - 160 = 7
step 11 long division 487 divided by 32 Since 7 is less than 32 your long division is done. You have your answer: The quotient is 15 and the remainder is 7.
So, 487 ÷ 32 = 15 with a remainder of 7
For longer dividends, you would continue repeating the division

Which pair of points has a slope of 4? Question 4 options: (0, 4), (4, 0) (3, 0), (–1, –1) (1, 4), (–1, 4) (0, –3), (1, 1)
Answers
Answer:
(0,-3) and (1,1)
Step-by-step explanation:
In order to have a slope of 4, the y coordinates need to differ by 4, and the x coordinates by 1. This is because slope is equal to rise/run. Rise being difference in y value and run difference in x.
In this pair of coordinates, the y coordinates differ in +4 (-3 and 1) and the x coordinate differs by 1 (0 and 1).
Therefore this is the pair of points with a slope of 4.
Hope this helped!
The pair of points that has a slope of 4 is the coordinate points (0, –3), (1, 1)
The formula for calculating the slope of a line passing through two points is expressed as:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
We need to get which of the coordinates will result in a slope of 4.
Using the coordinate points (0, –3), (1, 1)
[tex]m=\frac{1-(-3)}{1-0}\\m=\frac{1+3}{1}\\m=\frac{4}{1}\\m=4[/tex]
Hence the pair of points that has a slope of 4 is the coordinate points (0, –3), (1, 1)

Answers
Answer:
5 inches
Step-by-step explanation:
Given
Length of a cube = 1 inch
Required
Determine the edge length of the cube
If the container can take 125 cubes, then that's the volume
So:
[tex]Volume = 125in^3[/tex]
Volume of a cube is calculated as thus;
[tex]Volume = Length^3[/tex]
This gives;
[tex]Length^3 = 125[/tex]
Take cube root of both sides
[tex]Length = \sqrt[3]{125}[/tex]
[tex]Length = 5[/tex]
Hence, the length is 5 inches
