Answer:

21.5

Step-by-step explanation:

x is the radius of the circle.

If we draw a line from the circle's center to either end of the horizontal line, that line will also be a radius, so it will have length x. This forms a right triangle with side lengths 10 and 19 and hypotenuse x.

Using Pythagorean Theorem:

c² = a² + b²

x² = 10² + 19²

x² = 461

x ≈ 21.5

ozzi

hmmm units rates are just a matter of one above the other.

in this case is points/week.

9/15 points/weeks, we can just divide 9 ÷ 15 = 0.6, or 3/5.

so 0.6 points/weeks.

MODELING REAL LIFE A baseball is thrown up in the air. The table shows the heights $y$ (in feet) of the baseball after $x$ secon

nikklg [1K]

The equation for the path of the ball can be measured using a regression model calculator which produced the quadratic model ;

y(x) = - 16x² + 36x + 4
Height at x = 1.7 = 18.89 feets

The table given :

Time, x : __0.5 ___ 1 ____ 1.5 ____ 2

Height, y _ 18 ____22 ___ 24 ____ 12

Using technology such as a quadratic regression calculator or excel ;

The quadratic regression model obtained is :

y(x) = - 16x² + 36x + 4

The height after, 1.7 seconds, x = 1.7 can be calculated thus :

Put x = 1.7 in the equation :

y(1.7) = - 16(1.7)² + 36(1.7) + 4
y = 18.89 feets

Therefore, the height of the baseball after 1.7 seconds will be 18.89 feets.

Correct Option is D. Lines 72-75 ("Consider . . . happiness")

In lines 72-75, Wollstonecraft provides evidence that society’s leaders grant freedoms that privilege men. She argues that while society’s leaders believe they “are acting in the manner best calculated to promote [women’s] happiness,” their decisions don’t allow women to “contend for their freedom.”

Choices A, B, and C do not provide the best evidence that society’s leaders grant freedoms that privilege men over women.

<h3>The lines from passage are - </h3>

Passage 2 -

"Contending for the rights of woman, my main argument is built on this simple principle, that if she be not prepared by education to become the companion of man, she will stop the progress of 45 knowledge and virtue; for truth must be common to all, or it will be inefficacious with respect to its influence on general practice.

the local state university has a ratio of 5 professors to every 86 students there are 9460 students at State University what is

Phoenix [80]

As a ratio, 5:86 represents students to teachers

We can set up the equation as 5/86=x/9460

Multiply 9460 to both sides

5x9460/86=x

47300/86=x

x=550

There are 550 professors

Oduvanchick [21]

ANSWER

Find out the expression gives the percent of survey participants who chose swimming.

To proof

As given

75 girls at a summer camp were asked to complete a survey about their favorite outdoor activity.

27 girls chose swimming

32 girls chose hiking.

FORMULA

$Percentage = \frac{Part\times100}{whole}$

total girls = 75

girls chose swimming = 27

put in the formula

$= \frac{27\times100}{75}$

= 36%

36% of survey participants who chose swimming

Hence proved
