The length of major arc ACB with angle measure of 325° and diameter of 10 feet is (325/36)π

An equation is an expression that shows the relationship between two or more numbers and variables.

angle of arc ACB = 360° - 35° = 325°

The length of major arc ACB = (325/360) * π * 10 = (325/36)π

But in this we use d CAH cox there's adjacent and hypothenos here

Step-by-step explanation:

The first triangle

x²=62²-3.5²

x²=3844-12.25

x²=3831.75

The number of seconds it takes until the ball reaches max height is 2 seconds and the maximum height is 112 feet, and the number of seconds it takes until the ball hits the ground will be 6.9 seconds.

When a body is thrown in the air then the motion under the gravity is known as projectile motion.

A person standing close the the edge on the top of a 80 foot building throws a baseball vertically upward. the quadratic function

h(t) = -8t² + 32t + 80 models the ball's height above the ground, h(t), in feet, t seconds after it was thrown.

The number of second to reach at maximum height will be

We know that at maximum height, the rate will be zero. Then we have

       h'(t) = 0

-16t + 32 = 0

            t = 2 seconds

Then the maximum height will be

h(t) = -8(2)² + 32 x 2 + 80

h(t) = -32 + 64 +80

h(t) = -32 + 144

h(t) = 112 feet

Then the number of the seconds to reach at the ground will be

-8t² + 32t + 80 = -80

-8t² + 32t + 160 =0

t² - 4t - 20 = 0

Then t will be

[tex]\rm t = \dfrac{-(4) \pm \sqrt{(-4)^2 - 4 * 1 * -160}}{2*1}[/tex]

Then we have

t = 6.9 and -2.9

Answer:

A. $30.76

Step-by-step explanation:

First find the amount of tax applied to the bill.

Change 7% to a decimal by moving the decimal point two places left.

7% = 0.07

Multiply

25 x 0.07 = 1.75

Add the amount of tax to the total cost.

25 + 1.75 = 26.75

Now find the amount of the tip.

Change 15% to a decimal by moving the decimal two places left.

15% = 0.15

Multiply

26.75 x 0.15 = 4.0125

Add the amount of the tip back into the cost.

26.75 + 4.0125 = 30.7625

Round

30.7625 = 30.76

The probability that the number of free throws he makes exceeds 80 is approximately 0.5000.

The complete question is as below:-

A college basketball player makes 80% of his free throws. Over the course of the season, he will attempt 100 free throws. Assuming free throw attempts are independent, the probability that the number of free throws he makes exceeds 80 is approximate:____________.

A) 0.2000

B) 0.2266

C) 0.5000

D) 0.7734

Probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

Given that,

A college basketball player makes 80% of his free throws.

Over the course of the season, he will attempt 100 free throws.

Assuming free throw attempts are independent.

We have to determine,

The probability that the number of free throws he makes exceeds 80 is.

According to the question,

P(Make a Throw) = 80% = 0.80

number of free throws n = 100

Binomial distribution:

Mean: n x p = 0.80 x 100 = 80

Then, The standard deviation is determined by using the formula;

[tex]\sigma[/tex] = [tex]\sqrt{np(1-P)[/tex]

  = [tex]\sqrt{80\TIMES (1-0.80)[/tex]

  = [tex]\sqrt16[/tex]

  = 4

Therefore,

To calculate the probability that the number of free throws he makes exceeds 80 we would have to make the following calculation:

P ( x> 80) = 1 - P ( x < 80)

To calculate this value via a normal distribution approximation:

P ( [tex]Z < \dfrac{80-80}{4})[/tex] = 1-P(Z < 0 ) = 1 - 0.50 = 0.500

Hence, The probability that the number of free throws he makes exceeds 80 is approximately 0.5000.

Answer:

a = -2

p = 2

w = 3

Step-by-step explanation:

The degree of the polynomial is 6 as it has five turning points.

From inspection of the graph it appears that the curve touches
the x-axis at x = 1.  

Therefore, a factor is (x - 1) with multiplicity of 2:   (x - 1)²

The curve appears to cross the x-axis at x = 2.

Therefore, a factor is (x - 2), so p = 2

There appears to be a point of inflection at x = -1

Therefore, a factor is (x + 1)³, so w = 3

The y-intercept appears to be at (4, 0)

The product of the constants of the found factors is:  

⇒  1³ × (-1)² × (-2) = -2

Therefore, to find the value of a:

⇒ 4 = -2a

⇒ a = -2

Therefore, the polynomial function is:

f(x) = -2(x + 1)³ (x - 1)² (x - 2)

The distance of the tree from the house is: 45.99 feet

Angle of elevation is the angle the horizontal makes with the line of sight.

Analysis:

The tree lean towards a house meaning it does not lean on the house but a distance away from the house.

let the distance away from the house be d.

The line of sight intersects the top of the tree at a point.

The height of the point from the horizontal ground is 36 sin 87 = 36(0.998) = 35.92 feet

to find distance of the tree from the house, we use the angle of elevation which is 38  degrees. so that tan 38 = 35.92/d

d = 35.92/0.781  = 45.9 feet

In conclusion, the distance of the tree from the house is 45.9 feet

The coordinates of points C, E and G are respectively; C = (-0.75, 8.5),  E = (3.75, 7.5) and H= (7.5, 6)

The question stated that the line AB is divided into 7 equally spaced points that are tagged as C, D, E, F, G, H and I.

Note that the coordinates of A and B are  A(-3, 9) and B(9, 5) respectively and because they are known to be equally spaced, then it implies that point F is the midpoint of the line.

Thus (x, y) is said to be the coordinate of F. So;

x, y = (-3 + 9)/2, (9 + 5)/2

x, y = (6, 7)

Note also that H is the midpoint of FB. So,

H(x, y) = (6 + 9)/2, (5 + 7)/2

H(x, y) = (7.5, 6)

Since D is midpoint of A and F. therefore;

D(x, y) = (-3 + 6)/2, (9 + 7)/2

D(x, y) = (1.5, 8)

Since E is midpoint of F and D. So;

E(x, y) = (1.5 + 6)/2, (8 + 7)/2

E(x, y) = (3.75, 7.5)

C is midpoint of D and A. So;

C(x, y) = (-3 + 1.5)/2, (9 + 8)/2

C(x, y) = (-0.75, 8.5)

Therefore, we can say that the coordinates of points C, E and G are respectively; C = (-0.75, 8.5),  E = (3.75, 7.5) and H= (7.5, 6).
