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.)

PROVING A THEOREM In Exercises 7-9, write a two-column proof for the property. (See Example 3.) 7. Reflexive Property of Segment Congruence 8. Transitive Property of Angle Congruence 9. Transitive Property of Segment Congruence
The two-column proof are properties written with reason statements.
How to write two column proofs ?Two column proof is always written in two columns. This proof is consist of two parts, first one is the statement part which contain the exact statement of theorem and second part is reason part which consist of reason for that particular statement or equation. Both the parts are written in different columns, thus the proof is called as two-column proof.
In the given question , two-column proofs are as below :
for part 7 - Reflexive Property of Segment Congruence
To prove: (AB)' ≅ (AB)'
Proof :
Statements Reasons
segment AB Given
AB = |(AB)'| Definition of segment length
(AB)' = (AB)' Reflexive property
(AB)' ≅ (AB)' Definition of congruent segments
for part 8 - Transitive Property of Angle Congruence
To prove: ∠A ≅ ∠C
Proof :
Statements Reasons
∠A ≅ ∠B Given
∠B ≅ ∠C Given
m∠A = m∠B Definition of congruent angle
m∠B = m∠C Definition of congruent angle
m∠A = m∠C Definition of Transitive property
∠A ≅ ∠C Congruence property

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°
HURRY HELP!!!!!!!!!
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.

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.
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°.

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.
