Answer:

-2

Step-by-step explanation:

Using y=mx+c

ax+2y=10

Put y as subject of formula

2y= 10-ax

2y= -ax+10

using point (3,2)

2y= -ax+10

2(3)= -a(2)+10

6= -2a+10

Put a as subject of formula

-2a=10-6

-2a=4

a= 4/-2

a= -2

Answer:

24% of 33.50 = 80.40
67% of 87.99 = 58.96 (rounded up from 58.9533)
6% of 8.75 = 0.53 (rounded up from 0.525)

Step-by-step explanation:

to find the persentage of a number, you can first devide the whole number by 100, then multiply by the persentage ur figuring out, heres an example

for 24% of 33.50. we first devide 33.50 by 100

<em>33.50 / 100 = 3.35</em>

then multiply by 24

<em>3.35 * 24 = 80.40</em>

note if there are three numbers before the decimal point, and ur working with cash, always round up t the nearest hundredth

Prove : Cos^4A+sin^4A=1/4(3+cos4A)
Talja [164]

Answer:

1 = (sin^2 A + cos^2 A)^2 = sin^4 A + cos^4 A + 2 sin^2 A cos^2 A

so

sin^4 A + cos^4 A

= 1 - 1/2 sin^2 2A

= 1 - 1/4 (1- cos 4A)

= 1/4 (3+cos 4A)

Step-by-step explanation:

hope I helped

The area, A, of a circle is given by A = π r2, where r is the radius of the circle. Round all values to the nearest whole number
Artemon [7]

Answer:

A =363 cm^2

Step-by-step explanation:

A = π r^2

r = 11.3

Rounding to the nearest whole number

r =11

pi = 3.14

Rounding to the nearest whole number

pi = 3

A = 3 * 11^2

A = 3 *121

A =363 cm^2
