PLZ HELP!!
Peter and Xavier throw a ball in the air and create function models to show the trajectory. The variable x represents time in seconds after the ball was thrown and f(x) represents the height in meters.


The path of Peter's ball is represented by the function, f(x)=−4.9x2+22.54x+1.9.


The path of Xavier's ball is represented by the table.

srry if im wrong, but I tried and this question is hard

Answer:      16

Step-by-step explanation:

We first find out the number of graphic novels that Kaley reads, we set the number as k.

3k = 30

k = 10

Then Kaley reads 6 graphic novels fewer than Safara, which means that we plus 6 to the number of graphic novels that Kaley read,

k + 6 = 10 + 6 =16

Safara read 84 graphic novels.

The mathematical branch known as arithmetic deals with the study and application of numbers, their relationships, and mathematical observations. The fundamental ideas in number theory, measurement, and computation are frequently referred to as arithmetic (that is, the processes of addition, subtraction, multiplication, division, raising to powers, and extraction of roots).

As per the given data:

Kaley reads 6 graphic novels fewer than Safara ...(i)

Daniel reads 3 times as many as Kaley ...(ii)

Graphic novels Daniel read = 30

Kaley read = 3 × 30 = 90 novels  {from statement (ii)}

Safara read = 90 - 6 = 84 novels  {from statement (i)}

Hence, Safara read 84 graphic novels.

Answer:

$59.40

Step-by-step explanation:

0.08 x 55 = 4.40

55 + 4.40 = 59.40

Answer:

ok, so she made 10 bracelets in 2.5 hours. 22-12= 10

2.5 ÷10= .25 hours per bracelet

an hour is 60 minutes, so .25 x60= 15 minutes per bracelet

Answer:

10

Step-by-step explanation:

360*2 = 720. That leaves 180 words.

360/2 = 180

half the words would take half the time

4/2 = 2

8+2 = 10

Answer:

y = -x + 11

Step-by-step explanation:

The slope of the line y = -x + 4 is -1.

So the slope of our line is also -1 ( because they are parallel).

First use the point-slope form of the equation of a line:

y - y1 = m(x - x1) where m is the slope and (x1, y1) is a point on the line.

Here m = -1 and (x1, y1) = (6, 5).

So we have:

y - 5 = -1(x - 6)

y - 5 = -x + 6

y = -x + 11  <------ Slope intercept form.

Answer:

Undefined, it can be 20 cm, 22 cm or any value.A triangle has no limitations for any of each three sides.

Step-by-step explanation:

How it works? The triangles have no limits on their sides, but by their angles. Each triangle sums 180 degrees at the inner angles. If you don't have specific values for the angles it is not necessary to get some values for the third side. It could be 1, 2, .... or even 1000.

Answer:

Option (4)

Step-by-step explanation:

m(∠PZR) = [tex]\frac{2}{3}\pi[/tex]

Radius of the circle = 8

Since, length of an arc = [tex]\frac{\theta}{2\pi }(2\pi r)[/tex]

Here, θ = Central angle in radians

From the given formula,

m(arc PR) = [tex]\frac{\frac{2}{3}\pi}{2\pi }(2\pi \times 8)[/tex]

                = [tex]\frac{2}{6}(16\pi )[/tex]

                = [tex]\frac{16}{3}\pi[/tex]

Therefore, Option (4) will be the correct option.

Answer: 1. 18600000000 2. 645000

Step-by-step explanation:

62000000 x 300 = 18600000000

The area of Rhode Island is 1500. The area of Alaska land is a little more than 430.

1500 x 430 = 645000.

(I not sure if 645000 is the correct number, but that’s what I got).

Answer: RI 18,823.14

Step-by-step explanation:

I guess that we want to find the 12.6% of Rl 149,390

First, we assume that Rl 149,390 is the 100%

Then we can write an equation like:

Rl 149,390 = 100%

Then if the amount X is the 12.6%, we also have the equation:

X = 12.6%

Then we have the two equations:

X = 12.6%

Rl 149,390 = 100%

If we take the quotient between these two equations we get:

(X/Rl 149,390) = (12.6%/100%)

Solving this for X we get:

X =  (12.6%/100%)*(Rl 149,390) = RI 18,823.14

Step-by-step explanation:

Answer:

[tex]8\frac{6}{7}[/tex] as an improper fraction is [tex]\frac{62}{7\\}[/tex]

[tex]8\frac{6}{7}[/tex] in simplest form is [tex]8 \frac{6}{7\\}[/tex]

Step-by-step explanation:

To find the improper fraction of 8 6/7 is:

Multiply the denominator of the fraction by the whole number, 8. This gives you 56. Now, add the 56 with the numerator of the fraction. This gives you 62 as a sum. So, the improper fraction is 62/7.

You cannot simplify 8 6/7 because it is in simplest form.
