Answer:
a. 754cm³ (3 s.f.)
b. 415cm² (3 s.f.)
Step-by-step explanation:
Formulas (for easier reference):
Volume of cone: [tex]\pi[/tex]r²[tex]\frac{h}{3}[/tex]
Volume of hemisphere: [tex]\frac{2}{3}[/tex][tex]\pi[/tex]r³
Surface area of cone without base: [tex]\pi[/tex]rl
Surface area of hemisphere without base: 2[tex]\pi[/tex]r²
We can just apply the formulas for the question:
Volume of toy = ([tex]\pi[/tex] × 6² × [tex]\frac{8}{3}[/tex]) + ([tex]\frac{2}{3}[/tex] × [tex]\pi[/tex] 6³)
= 96[tex]\pi[/tex] + 144[tex]\pi[/tex]
= 240[tex]\pi[/tex]
= 754cm³ (3 s.f.)
Surface area of toy = ([tex]\pi[/tex] × 6 × 10) + (2 × [tex]\pi[/tex] × 6²)
= 60[tex]\pi[/tex] + 72[tex]\pi[/tex]
= 132[tex]\pi[/tex]
= 415cm² (3 s.f.)

Answer:
x = 4
Step-by-step explanation:
3x - 4y = 36
5x + 2y = 8 ( multiply all by two )
3x - 4y = 36
10x + 4y = 16

A discount sports store has been open for 17 years. For this time period, the store’s annual revenue, R (in millions of dollars), can be modeled by the function
(picture) where t represents the number of years since the store opened. Determine the number of years the store was in business when the revenue amount reached $8.2 million.
9514 1404 393
Answer:
10 years
Step-by-step explanation:
We want to find the value of t when R = 8.2. Equivalently, we want to find t when ...
0.001(-t^3 +16t^2 +900t -1400) -8.2 = 0
A graphing calculator is useful for finding real solutions to this equation. The attachment shows the store was in business 10 years when revenue reached 8.2 million.

Answer: [tex]-p^2-(q+r)^2[/tex]
Work Shown:
I'm assuming your teacher wants you to factor as much as possible.
[tex]-p^2-q^2-r^2-2qr\\\\-p^2-q^2-2qr-r^2\\\\-p^2-(q^2+2qr+r^2)\\\\-p^2-(q+r)^2\\\\[/tex]
In the last step, I used the rule that [tex](a+b)^2 = a^2+2ab+b^2[/tex]
We cannot factor any further. If the first term was [tex]p^2[/tex] instead of [tex]-p^2[/tex], then we could use the difference of squares factoring rule.

The difference between the x is 3 and this is the run
The difference between the y is 7 and this is the rise.
The slope is rise over run so we have:
7/3

If WXY is equilateral and WZY is
isosceles, find each missing measure.
Answer:
m∠1 = 60°
m∠2 = m∠4 = 39°
m∠3 = m∠5 = 21°
Step-by-step explanation:
ΔWXY is a equilateral angle,
Therefore, all angles of the the triangle are equal in measure.
m∠W + m∠X + m∠Y = 180°
3m∠W = 180°
m∠W = 60°
Since, ΔWZY is an isosceles triangle,
m∠3 = m∠5
m∠3 + m∠Z + m∠5 = 180°
m∠3 + 138° + m∠3 = 180°
2m∠3 = 180 - 138
m∠3 = 21°
Therefore, m∠3 = m∠5 = 21°
Since, m∠2 + m∠3 = 60°
m∠2 = 60 - 21
= 39°
Since, m∠4 + m∠5 = 60°
m∠4 = 60 - 21
= 39°
m∠1 = 60°
how to solve for x???
Answer:
50 degrees
Step-by-step explanation:
Since this is an isosceles triangle, and the measurements on the left and right are the same, that means that both angle measurements on the bottom are the same.
180 - 80 = 100
100/2 = 50
An airplane is descending to a runaway. At an altitude of 15.2 miles, its horizontal distance to the runway is 60 miles. Find the angle of descent.
Answer-
The angle of descent is 14.2
The measure of the angle of the descent will be 14.22°.
What is a right-angle triangle?It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.
Trigonometric functions examine the interaction between the dimensions and angles of a triangular form.
A plane is sliding to a runaway. At a height of 15.2 miles, its level distance to the runway is 60 miles.
The tangent of angle θ is the ratio of the height to the base of the right-angle triangle.
The measure of the angle of the descent will be given as,
tan θ = 15.2 / 60
tan θ = 0.2533
θ = tan⁻¹ 0.2533
θ = 14.22°
The measure of the angle of the descent will be 14.22°.

A candle burns down at the rate of 0.5 inches per hour. The original height of the candle was 8 inches.
Part A: Write a list of 6 ordered pairs to show the height of the candle in inches (y) as a function of time in hours (x) from the first hour after it started burning. For example, the point (0, 8) would represent a height of 8 inches after 0 hours. Explain how you obtained the ordered pairs. (5 points)
Part B: Is this relation a function? Justify your answer using the list of ordered pairs you created in Part A. (2 points)
Part C: If the rate at which the candle burned was 0.4 inches per hour instead of 0.5 inches per hour, would the relation be a function? Explain your answer using input and output values. (3 points)
Answer:
A: (1, 8.5)(2, 8)(3, 7.5)(4, 7)(5, 6.5)(6, 6) B: Yes C: Yes Step-by-step explanation: A: I obtained the ordered pairs by subtracting .5 inches from 9 inches for each second. B: Yes because for every input there is only one output. For example after 2 seconds, the candle is 8 inches.
