Answer:

a). Function is not a quadratic function

b). Quadratic function.

Step-by-step explanation:

1.a). x        y         Ist difference     IInd difference

     -2      -1                 -                             -

     -1        0           0 - (-1) = 1                    -

      0       4            4 - 0 = 4              [tex]d_1[/tex] = 4 - 1 = 3

      1        9            9 - 4 = 5              [tex]d_2[/tex] = 5 - 4 = 1

      2       15          15 - 9 = 6             [tex]d_3[/tex] = 6 - 5 = 1

Since, 2nd difference [tex]d_1[/tex], [tex]d_2[/tex] and [tex]d_3[/tex] from the table are not common, function represented by the table is not a quadratic function.

b). -3x²+ x = y - 11

   -3x² + x + 11 = y

    y = -3x² + x + 11

Since, the highest degree term of the given function is of 2nd degree given function is a quadratic function.

Answer:

35.5 feet

Step-by-step explanation:

x + x + 3 + x + 5 = 99.5

3x + 8 = 99.5

3x = 91.5

x = 30.5

Largest side = (x+5)

30.5 + 5 = 35.5 feet

Step-by-step explanation:

2x + 5y = 1 and -3x + 4y = -13

From equation 1, 2x = 1 - 5y, x = 0.5 - 2.5y.

Substitute into equation 2:

-3(0.5 - 2.5y) + 4y = -13

-1.5 + 7.5y + 4y = -13

11.5y = -11.5

y = -1.

We know that x = 0.5 - 2.5y = 0.5 - 2.5(-1) = 3

Hence x = 3, y = -1.

Answer:

840 m

Step-by-step explanation:

Please refer to the attached photo.

In the attached photo, h is the height of the cliff.

The following data were obtained from the attached photo:

Opposite = h

Adjacent = 1200

θ = 35 °

The height, h of the cliff can be obtained by using the Tan ratio as follow:

Opposite = h

Adjacent = 1200

θ = 35 °

Tan θ = Opposite /Adjacent

Tan 35 = h/1200

Cross multiply

h = 1200 × Tan 35

h = 1200 × 0.7

h = 840 m

Therefore, the cliff is 840 m tall.

Answer:

Kindly check explanation

Step-by-step explanation:

Given the question:

Play 1: Quarterback was sacked for a loss of 4 yards

Play 2 : Another loss of 10 yards

Play 3: a gain of 12 yards

Write an addition expression to represent the situation. Then find the sum and explain its meaning.

A loss of 4 yards = - 4

Loss of 10 yards = - 10

Gain of 12 yards = + 12

Addition expression for the scenario :

(-4) + (-10) + 12

Result :

-4 + (-10) + 12

= - 4 - 10 + 12

= - 14 + 12

= - 2

Hence, after two consecutive losses of 4 and 10 yards, the team wins 12 yards on the third play and the aggregate yards lost is reduced to 2 yards.

Step-by-step explanation:

formula for sa of a cylinder is 2pir^2+2pirh

you just fill in the r and h

Answer:

[tex]\approx 408.2[/tex] in²

Step-by-step explanation:

The surface area of a cylinder can be represented as [tex]2\pi rh+2\pi r2[/tex]. Let's represent pi as 3.14 and r is 5 and h is 8.

[tex](2\cdot 3.14\cdot 5\cdot8) + (2\cdot 3.14 \cdot 5^2)\\\\251.2 + 157 = 408.2[/tex]

This means the surface area of this cylinder is 408.2 in².

Answer:

46,499 digits

Step-by-step explanation:

Total pages of book = 11,521

9 pages numbered 1 - 9 that need 1 digit each = 9 × 1

= 9 digits

90 pages numbered 10 - 99 that need 2 digits each = 90 × 2

= 180 digits

900 pages numbered 100 - 999 that need 3 digits each = 900 × 3

= 2,700 digits

9000 pages numbered 1000 - 9999 that need 4 digits each = 9000 × 4

= 36,000 digits

1522 pages numbered 1000 - 11521 that need 5 digits each = 1522 × 5

= 7,610 digits

Total digits needed = 9 digits + 180 digits + 2,700 digits + 36,000 digits + 7,610 digits

= 46,499 digits

Answer:

$78

Step-by-step explanation:

Here we have to find total distance first then find amount of gasoline used based on distance traveled by car in one gallon.

_____________________________________________

Given

time = 12 hours

speed = 64 miles per hour

we know distance = speed * time

distance = 12*64 = 768 miles.

Thus, car ran 768 miles.

given that car gets an average of 32 miles per gallon.

It means in one gallon gasoline car travels 32 miles.

let the gallons used be x

in 1 gallon gasoline car travels 32 miles.

in 1*x gallon gasoline car travels 32*x miles = 32x

Thus, 32x should be equal to 768 miles as car traveled that much only

32x = 768 miles

x = 768/32 = 24

Thus, gallons of gasoline used is 24.

Cost of 1 gallon gasoline = $3.25

since, gallons found is 24, we multiply lHS and RHS by 24

Cost of 1 *24= 24 gallon gasoline = $3.25*24 = $78

Thus,

cost of 24 gallon is $78 which will be the gasoline cost for the trip.

Step-by-step explanation:

#3 let the two consecutive integers be a, a+1.

a+a+1=345

2a+1=345

2a=345-1

2a=344

a=344/2=172...

the integers are 172, 173

#5 let the consecutive even integers be a, a+2

a+a+2=446

2a=446-2

2a=444

a=444/2=222..so the even integers are 222, 224

Answer:

23/10. or 2  3/10

Step-by-step explanation:

Answer:

g = 10/(ae)

Step-by-step explanation:

When variables are shown like that, in reality they are multiplied:

aeg = 10 is the same as a * e * g = 10

Isolate the variable, g. Note the equal sign, what you do to one side, you do to the other. Simply divide variables a & e from both sides:

(aeg)/ae = (10)/ae

g = 10/ae

g = 10/(ae) is your answer.

Answer:

10 Marbles in total

Step-by-step explanation:

A ratio is pretty much a diversity between two things.

Examples:

Apples, green vs red

1 green apple : 3 red apples

Your Questions Explanation:

Marbles, small vs large

1 small marble : 3 large marbles

BUT if there are 8 MORE large marbles than small marbles

what that looks like as a ratio...

1:9

Then in total there are 10 marbles in the bag.

The scale is  1 cm: 12.5 km

To get this answer, you start off with the ratio 4 cm: 50 km which is given to us. It means that 4 cm corresponds to 50 km.

Divide both parts of the ratio by 4

4/4 = 1

50/4 = 12.5

The ratio 4 cm: 50 km simplifies to 1 cm: 12.5 km

1 cm on paper represents 12.5 km in real life.

The scale is 1cm on map represents 12.5 km in actual distance.

Suppose the initial measurement of a figure was x units.

And let the figure is scaled and new measurement is of y units.

Since the scaling is done by multiplication of some constant, that constant is called scale factor. Let that constant be 's'.

Then we have:

[tex]s \times x = y\\s = \dfrac{y}{x}[/tex]

Thus, scale factor is the ratio of the new measurement to the old measurement.

The ratio 4 cm: 50 km which is given to us means that 4 cm corresponds to 50 km.

Divide both parts of the ratio by 4;

4/4 = 1

50/4 = 12.5

Thus, The ratio 4 cm: 50 km simplifies to 1 cm: 12.5 km

Therefore, 1 cm on paper represents 12.5 km in real life.
