Answer:
Part 1
Given equation:
C(t) = -0.30 (t – 12)² + 40For t = 0
C(t) = -0.30 (0 - 12)² + 40 C(t) = -0.30 (-12)² + 40 C(t) = -3.2For t = 12 (noon)
C(t) = -0.30 (12 - 12)² + 40 C(t) = -0.30 (0)² + 40 C(t) = 40For t = 24 (midnight)
C(t) = -0.30 (24 - 12)² + 40 C(t) = -0.30 (12)² + 40 C(t) = -0.30 × 144 + 40 C(t) = - 43.2 + 40 C(t) = -3.2Part 2
attached below
Part 3
C(t) = –0.30(t – 12)² + 40 F(t)=9/5C(t)+32Substituting the values:
F(t)=9/5{–0.30 (t – 12)² + 40}+32 F(t) = -0.54 (t – 12)² + 72 + 32 F(t) = -0.54 (t – 12)² + 1045, 6 and 7, should be simplish
good luck, i hope this helps :)
Answer:
problems 4,5,6,7 (make sure you add °C to the answers given in step one above) *note, these answers given in both answers could be used for any of the deserts chosen, they all have the same formula given.
Step-by-step explanation:
4) box 12
(12,40)
f(12)= 9/5 (40)+ 32
f(12)= 72 +32
f(12)= 104 ° F
box 24
(24, -3.2)
f(24)= 9/5 (-3.2) +32
f(24) = -5.76 +32
f(24)= 26.24 °F
5.
substitute the given C(t) equation into the conversion formula
F(t)= 9/5C(t)+32.
We know from the information given that C(t)=−0.30(t−12)^2 +32
to solve:
F(t)= 9/5[−0.30(t−12)^2+40]+32
F(t)=1.8(−0.3t^2+7.2t−3.2)+32
F(t)=−0.54t^2+12.96t−5.76+32
F(t)=−0.54t^2+12.96t+26.24
6.
on the graph plot the three points (0,-0.32), (12,104), (24,-0.32)
It draw the lines to connect the bottom two points to 12, 104, It should look like upside down V but curved softer like the graph in answer number 2.
7. The changes made to the graph of C(t) to transform it to F(t) was changing the noon temperature (plot point) from 40° C to 104° F. It increased the steepness of the graph.

A chef cooked vegetables for 22 customers. The chef cooked 1/3 pound of potatoes and
1/4 pound of green beans for
each customer.
How many pounds of vegetables did the chef cook for these customers all together?
Answer:
The chef cooked 1/3 pound of potatoes and
1/4 pound of green beans for
each customer.
so. Sum of all vegetables for one customer = 1/3 pound of potatoes + 1/4 pound of green beans
= 1/3 + 1/4 pound
= 7/12 pound
so. Sum of all vegetables for 22 customer = (7/12 pound ) 22
= 22/12 pound
= 11/6 pound

what is the surface area of this design?
Answer:
197 in
Explanation:
6.4x5=32
9x5=45
5×5=25x4=100
5×4×0.5=10×2=20
32+45+100+20=197
Answer:
197 inches squared
Step-by-step explanation:
Break down the sides,
Side 1, (front) 5*5=25
Side 2, (slanted compound shape) break down compound into triangle and square: 5*5=25, 4*5/2=10
Side 3, (slanted compound shape) break down compound into triangle and square: 5*5=25, 4*5/2=10
Side 4, (top slanted) 6.4*5=32
Side 5, (Bottom) 5*5=25
Side 6, (Back) 9*5=45
Add all together, 25+25+10+25+10+32+25+45=197

juan drove 126 miles in 3 hours. If he continued at the same rate, how long would it take to travel 336 miles?
Answer:
8 hours
Step-by-step explanation:
First you divide 126 by 3 to get the Miles Per Hour, you should get 42 Miles Per Hour, then, just divide 336 by 42 to get the numbers of hours he will have to drive, (which is 8)
Answer:
8 hours
Step-by-step explanation:
126 miles - 3 hours
336 miles - x hours
Cross multiply
126x = 336 x 3
126x = 1008
Divide both sides by 126
x = 1008/126
x = 8

ABC and is a straight line
Work out the length of AC
Give your answer to 1 decimal place
Answer:
19.2
Step-by-step explanation:
I hope it helps you.....
Answer:
AC ≈ 19.2 cm
Step-by-step explanation:
Using Pythagoras' identity in Δ BCD to find BC
BC² + BD² = DC² , that is
BC² + 12.6² = 19.3²
BC² + 158.76 = 372.49 ( subtract 158.76 from both sides )
BC² = 213.73 ( take the square root of both sides )
BC = [tex]\sqrt{213.73}[/tex] ≈ 14.62
Using the tangent ratio in Δ ABD to find AB
tan20° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{AB}{BD}[/tex] = [tex]\frac{AB}{12.6}[/tex] ( multiply both sides by 12.6 )
12.6 × tan20° = AB , then
AB ≈ 4.59
Then
AC = AB + BC = 14.62 + 4.59 ≈ 19.2 cm ( to 1 dec. place )

The diagram shows triangle ABC.
Which statement would prove that triangle ABC is a right triangle?
a. The slope of segment AB and the slope of segment BC = 1
b. The slope of segment AB and the slope of segment BC = -1
c. The slope of segment AB is 1 and the slope of segment BC is -1
d. The distance from A to B is equal to the distance from B to C
The statement where it proved that triangle ABC is a right triangle should be option b. The slope of segment AB and the slope of segment BC = -1
Right triangle:We know that in the right triangle both the legs should be perpendicular to each other also the product of slopes of perpendicular should be - 1.
So based on this, we can say that the slope of segment AB and the slope of segment BC is equivalent to -1
Therefore, the option b is correct.
