Answer:

5m  the last option is correct

Step-by-step explanation:

by phythagorean theorem

hypotenuse^2=base^2+altitude^2

hypotenuse ^2= (4)^2+(3)^2

                        =16+9

                        =25

taking square root on both isdes

 hypotenuse=5 m

Answer:

[tex]sinC = \frac{7}{25}\\~\\cosC = \frac{24}{25}\\~\\tanC = \frac{7}{24}[/tex]

Step-by-step explanation:

To get the sine of a non-right angle C in a right triangle, just divide the side opposing C by the long side. To get the cosine, divide the sides at C (shorter by longer). To get the tangent, divide the sine by the cosine.

Let's go:

[tex]sinC = \frac{7}{25}\\~\\cosC = \frac{24}{25}\\~\\tanC = \frac{7}{25} / \frac{24}{25} = \frac{7}{24}[/tex]

Answer:

sin(7/25), cos(24/25), tan(7/24)

Step-by-step explanation:

The sin, cos, and tan are found through the sides of the triangle.

The acronym SOH CAH TOA can be used to find which goes where.

S = sin

C = cos

T = tan

O = opposite

A = adjacent

H = hypotenuse

since it asks to use  angle C you start from there, for sin its O/H hint by the SOH the rest are the same.

Alejandro and Noya were told to draw a net for an octagonal prism. Which statement about the students' nets is true?

Answers

Complete question is;

Alejandro and Noya were told to draw a net for an octagonal prism. Which statement about the students’ nets is true? Both nets do not form octagonal prisms.

A) Only Alejandro’s net is correct.

B) Only Noya’s net is correct.

C) Neither net is correct.

D) Both nets are correct.

Answer:

C) Neither net is correct.

Step-by-step explanation:

From the second attached image, we can see what an octagonal prism looks like when it is opened to show all the faces.

However, looking at the first attached image showing the net drawings of boya and Alejandro, it is very clear that none of them got the required shape for the octagonal prism. Therefore, we can conclude that neither of the nets are correct.

Write the standard form of the equation of the line through the given point with the given slope. point (-1.0); slope -2/3​

Answers

Answer:

Step-by-step explanation:

When given a point and a slope, the best equation to use is the point-slope formula, y - k = m(x - h)

which here becomes:

y - 0 = m(x + 1), or y = (-2/3)(x + 1), or  y = (-2/3)x - 2/3

If you want this in standard form, first clear the fractions by multiplying all terms by 3:  3y = -2x - 2

Now add 2x to both sides, obtaining:  2x + 3y = -2 (in "standard form."

Silas was curious if sample minimum was an unbiased estimator of population minimum. He started with a large
normally distributed population of test scores whose minimum was 51 points.
He then took a random sample of 6 tests and calculated the minimum of the sample. He replaced those tests
and repeated this process for a total of 40 trials. His results are summarized in the dotplot below, where each
dot represents the minimum score from a sample of 6 tests.

functions

OB. AB) = x= 1962–31x-3
x-2
O C. FX) =

Answers

Given:

The graph of rational function.

To find:

The rational function.

Solution:

If the graph of a rational function has a vertical asymptote at [tex]x=a[/tex], then [tex](x-a)[/tex] must be a factor of the denominator of that rational function.

From the given graph it is clear that the graph has two vertical asymptotes. One is at [tex]x=-1[/tex] and another one is at [tex]x=3[/tex].

It means, [tex](x-3)[/tex] and [tex](x+1)[/tex] are the only two factors of the denominator of the rational function.

In option A, the factors of the denominator are different from [tex](x-3)[/tex] and [tex](x+1)[/tex] .

In option B, the denominator has an extra factor [tex]x-2[/tex].

In option C, the denominator has only two factors [tex](x-3)[/tex] and [tex](x+1)[/tex].

Therefore, the correct option is C.
