After a storm, a 36-foot tall tree is now leaning
towards a house, making an 87° angle with the
ground. If the angle of elevation from the base of
the house to the top of the tree is 38°, how far is the
tree from the house?
The distance of the tree from the house is: 45.99 feet
What is angle of elevation?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

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)

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) = -8t^2 + 32t + 80 models the ball's height above the ground, h(t), in feet, t seconds after it was thrown.
How do I efficiently determine...
-- how many seconds it takes until the ball reaches max height
-- the maximum height
-- how many seconds it takes until the ball hits the ground
without graphing?
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.
What is a projectile motion?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

A college basketball player is known to make 80% of his free throws. Over the course of the season, he will attempt 100 free throws. Assuming free-throw attempts are independent, what is the probability that the number of free throws he makes exceeds 80
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
What is probability?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.

Jason and his friend went to a restaurant for dinner. The food that they ordered cost $25. A 7% sales tax was applied to the total.
After the sales tax was applied, Jason paid a 15% tip on the total bill. How much did Jason pay at the restaurant?
OA. $30.76
OB. $28.75
OC. $30.50
OD. $26.75
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

Select the correct answer from each drop-down menu. Segment AB has seven equally spaced points on it. Starting at A and moving left to right, the points are C, D, E, F, G, H, and I. In the diagram, is divided into equal parts. The coordinates of point A are (-3, 9), and the coordinates of point B are (9, 5). The coordinates of point C are . The coordinates of point E are . The coordinates of point H are .
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)
What is the Coordinates of the Line Segment about?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).
