A tree cast a 16 foot long shadow on level ground a forestry student uses a clinometer to determine the sun is that a 70° angle of elevation what is the height of the tree to the nearest whole foot
Answer:
15foot
Step-by-step explanation:
The set up will give a right angled triangle.
The length of the shadow will be the hypotenuse = 16foot
The height of the tree will be the opposite = x
The angle of elevation = 70°
Using the SOH CAH TOA trig identity
Sin theta = opposite/hypotenuse
Sin 70 = x/16
x=16sin70
x = 15.04feet
Hence the height of the tree to the nearest whole foot is 15foot

Ronin kicks a ball over the gate of the first floor balcony. The function h(t)=-36t^2+288t+9 can be used to model the height of the ball where t is the time in seconds after the ball kicked and h(t) is the height in feet 1. Find the time in Devon which the ball reaches it maximum height
Answer: 4 seconds
Step-by-step explanation:
Given: The function [tex]h(t)=-36t^2+288t+9[/tex] can be used to model the height of the ball where t is the time in seconds after the ball kicked and h(t) is the height in feet.
Differentiate the given function with respect to t , we get
[tex]h'(t)=-36(2)t+288=-72t+288[/tex]
Put h'(t)=0
[tex]\Rightarrow\ -72t+288=0\Rightarrow\ t=\dfrac{288}{72}\\\\\Rightarrow\ t=4[/tex]
Also, [tex]h''(t)=-72<0[/tex]
By second derivative test, h(t) is maximum at t=4.
Hence, the time in Devon which the ball reaches it maximum height = 4 seconds

Answer:
The volume of the cone = 101 cubic inches.
Step-by-step explanation:
Given
Radius of the cone = r = 4 in
Height h of the cone = h = 6 in
To determine
The volume in cubic inches rounded to the nearest whole number.
Using the formula to determine the volume of the cone
V = πr²h/3
substitute r = 4, h = 6, and π = 3.142 in the formula
V = (3.142) (4)²(6) / 3
V = (3.142) (4)² (2)
V = (3.142) (16) (2)
V = (3.142) (32)
V = 100.544
V ≈ 101 cubuc inches (rounded to the nearest whole number)
Therefore, the volume of the cone = 101 cubic inches.

Solve x2 + 6x = -6. If exact roots cannot be found, state the consecutive
integers between which the roots are located.
x²+6x＝-6 ‖+6
x²+6x+6＝0
x1＝-(6/2)+√((6/2)²-6)＝ -3+√(3) or ≈ -1.267
x2＝-(6/2)+√((6/2)²-6)＝ -3-√(3) or ≈ -4.732
The roots of the quadratic equation, x² + 6x = - 6 are between - 2 and - 1,
and 1 and 2.
What is a quadratic equaton?A quadratic equation is an algebraic expression in the form of variables and constants.
A quadratic equation has two roots as its degree is two.
Given, x² + 6x = - 6.
We know in ax² + bx + c = 0, x = ± √(b² - ac)/2a.
∴ x² + 6x + 6 = 0.
x = ± √(36 - 24)/2×1.
x = ± √(12)/2.
x = ± (2√3)/2.
x = ± √3.
We know √3 is between 1 and 2 and - √3 is between - 2 and - 1.

Variable:
Equation:
Solution:
Answer:
Step-by-step explanation:
1.
(im gonna use x as a variable for all of these problems)
first to find how much each square foot costs subtract 80 from the total first
287 - 80 = 207
then divide $207 between 60 square feet
207 / 60 = $3.45
so each square foot is $3.45
our equation to find the cost would be
y = 3.45x + 80
2.
first lets find out how much the scarves are
5 x 12 = $60
then subtract that from the total
125 - 60 = $65
for 5 sister to each have 2 pairs of socks that means theres 10 pairs of socks
divide ypur rmaining money by the 10 pairs
65 / 10 = $6.50
so each pair of socks is $6.50
3.
first lets make an equation for the ymca costs
y = 15x + 20
then plug in 185 for y
185 = 15x + 20
solve for x
165 = 15x
11 = x

A dressmaker needs to cut 12-inch pieces of ribbon from rolls of ribbon that are 6 feet in length. How many 12-inch pieces can the dressmaker cut from 10 of these rolls of ribbon?
Before you try that problem, answer the question below.
How many \textbf{inches}inches of ribbon does the dressmaker have, in total?
Answer:
60
Step-by-step explanation:
because 12 inches is one foot so there’s 6 feet per 6 feet of ribbon and there’s 10 of these ribbons so 6 times 10 is 60
The 12-inch pieces the dressmaker can cut from 10 of these rolls of ribbon will be 60 strips .
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
It is given that the dressmaker has 720 inches of ribbon.
dressmaker needs to cut 12-inch pieces of ribbon from rolls of ribbon that are 6 feet in length.
The amount of rolls she has = 10 rolls
so,
6(strips per roll) x 10(amount of rolls) = 60 strips
