Answer:

see below

Step-by-step explanation:

1.)

(0, 4)

(1, 7)

$\frac{7-4}{1-0} = 3$

y = 3x + b

(4) = 3(0) + b

b = 4

y = 3x + 4

Rate of change: 3 initial value: 4

2.)

(0, -5)

(1, -3)

$\frac{-3-(-5)}{1-0} = 2$

y = 2x + b

(-5) = 2(0) + b

b = -5

Rate of change: 2 initial value: -5

Solve each equation for 0° < x < 360°.

Ipatiy [6.2K]

Answer:

Hence value for x is 0 degree

Step-by-step explanation:

Given:

x limits are (0 to 360) degrees and

Cos(x+45)+cos(x-45)=Sqrt(2)

To Find:

value for X

Solution:

Given equation cos(x+45)+ cos(x-45)

Is similar to cos(A+B) +cos(A-B)=2cosA*cosB

Now comparing with general formula we get ,

A=x and B=45

Hence given equation becomes as ,

$2cosA*cosB=Sqrt(2)$

$2Cosx*cos45=Sqrt(2)$

$cosx=Sqrt(2)/(2*cos45)..........cos45=1/$ $\sqrt{2}$

$Cosx=Sqrt(2)/Sqrt(2)$

$cosx=1$

x= 0

Hence value for x is 0 degree

Write 60 as the product of two factors

Ilya [14]

Use a factor tree to express 60 as a product of prime factors. So the prime factorization of 60 is 2 × 2 × 3 × 5, which can be written as 2 2 × 3 × 5.

Klara downloaded 264 pictures from her cell phone to her computer. These pictures took up 528 megabytes of space on her computer

Feliz [49]

70, because 528 divides by 264 is 2, which means each picture is 2 megabytes, so therefore 35x2 = 70
