Water boils at 100LaTeX: ^\circ∘ Celsius or 212LaTeX: ^\circ∘ Fahrenheit. Water freezes at 0LaTeX: ^\circ∘ Celsius or 32LaTeX: ^
Lubov Fominskaja [6]

Answer:

F = 1.8C +32

F = 86^{\circ}F

Step-by-step explanation:

Represent Celsius with C and Fahrenheit with F.

So, we have:

(C_1,F_1) = (100,212)

(C_2,F_2) = (0,32)

Solving (a): Represent as a linear equation

First, we calculate the slope:

m = \frac{F_2 - F_1}{C_2 - C_1}

This gives:

m = \frac{32 - 212}{0 - 100}

m = \frac{-180}{- 100}

m = 1.8

The linear equation is then calculated using:

F - F_1 = m(C -C_1)

Where

(C_1,F_1) = (100,212)

m = 1.8

F - 212 = 1.8(C -100)

F - 212 = 1.8C -180

Make F the subject

F = 1.8C -180+212

F = 1.8C +32

Solving (b): The value of F when C = 30

Substitute 30 for C in F = 1.8C +32

F = 1.8 * 30 + 32

F = 54 + 32

F = 86

An online furniture store sells chairs for $150 each and tables for $400 each. Every day, the store can ship no more than 30 pie
ivolga24 [154]

Answer:

minimum of 13 chairs must be sold to reach a target of $6500

and a max of 20 chairs can be solved.

Step-by-step explanation:

Given that:

Price of chair = $150

Price of table = $400

Let the number of chairs be denoted by c and tables by t,

According to given condition:

t + c = 30 ----------- eq1

t(150) + c(400) = 6500 ------ eq2

Given that:

10 tables were sold so:

t = 10

Putting in eq1

c = 20 (max)

As the minimum target is $6500 so from eq2

10(150) + 400c = 6500

400c = 6500 - 1500

400c = 5000

c = 5000/400

c = 12.5

by rounding off

c = 13

So a minimum of 13 chairs must be sold to reach a target of $6500

i hope it will help you!

F(x) = -2x²-2x+10, find f(2)
beks73 [17]

Answer:

f(2) = -2

Step-by-step explanation:

Substitute 2 everywhere you see an x so f(2) = -2(2^{2}) - 2(2) + 10 so

f(2) = -2(4) - 4 + 10, so f(2) = -8-4+10, f(2) = -12+10, f(2) = -2
