A circle has a diameter with endpoints at (18, -13) and (4, -3).

NO FAKE ANSWERS PLEASE IM BEGGING YOU 40 POINTS!!!!!! PLEEASEEEE HELP!!!!!!!!!!!!!! I already solved half of it pls help on part

Vikki [24]

Answer:

Part 1

Given equation:

C(t) = -0.30 (t – 12)² + 40

For t = 0

C(t) = -0.30 (0 - 12)² + 40

C(t) = -0.30 (-12)² + 40

C(t) = -3.2

For t = 12 (noon)

C(t) = -0.30 (12 - 12)² + 40

C(t) = -0.30 (0)² + 40

C(t) = 40

For 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) = -3.2

Part 2

attached below

Part 3

C(t) = –0.30(t – 12)² + 40

F(t)=9/5C(t)+32

Substituting 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 + 104

5, 6 and 7, should be simplish

good luck, i hope this helps :)

Answer:

Answer:B AND E ARE CORRECT

Answer:B AND E ARE CORRECTStep-by-step explanation:

WE'RE SIMPLY COMPARING TWO SIMILAR SIDES OF THE FIQURES. NOTE: the pattern must be the same I mean if we start with the larger figure being on top then that is how the rest comparisons should follow. I hope this will help!

Janie and Jasmine are playing three games at an arcade. Each of the games requires either 2, 3, or 4 tokens. The girls plan to p

Brrunno [24]

Answer:

m+2n+2p=16 tokens or m+2(n+p)= 16 tokens

Step-by-step explanation:

First, we must understand how many tokens they have.

Janie played the 3-token game four times, so she used 12 tokens (3n x 4 = 12). Jasmine played the 4-token game five times, so she used 20 tokens (4p x 5 = 20).

Added up, the girls have 32 tokens (12+20 = 32 tokens (t)).

In order to play a round of the three games, 9 tokens are required (m+n+p = 9 / 2+3+4 = 9) by each girl. (32t-18t=14) 14 tokens are left after taking a ride in every game each. 14 left divided by 2 will leave 7 more tokens for each girl. You can split these 7 tokens into an n+p = 7 tokens

Thus,

Each girl can ride as follows:

m+2n+2p=16 tokens or m+2(n+p)= 16 tokens

What is the value of x

kodGreya [7K]

Answer:

3.92 approximately 4

Step-by-step explanation:

let us first find angle at F

40⁰+50⁰+F= 180 (sum of angles in a triangle)

90⁰+F= 180⁰

F= 180⁰-90⁰

F = 90⁰

using sine rule

3/sin 50 = x/sin 90

3/0.7660= x/ 1

0.7660x=3

x= 3/0.7660

x= 3.92 approximately 4
