Answer:

Step-by-step explanation:

Question 4

we have two sides and an angle so we should use law of cosines to solve for c

[tex]7=\sqrt{5^2+c^2-2*5*c*cos(35)}\\\\49=25+c^2-10*c*cos(35)\\25=c^2-8.19152044289c\\c^2-8.19152044289-25=0\\[/tex]

(using the quadratic formula)

c=10.48131

To solve for b use the law of cosines again

[tex]5=\sqrt{7^2+10.48131^2-2*7*10.48131*cos(B)\\[/tex]

B=24.1858343432

2. Write an equation of the line that passes through (-2,3) and is parallel to the line y=2x-1.

Answers

Hello there! :)

Parallel lines have identical slopes.

So if one line has a slope of 2, then the line parallel o it would have the same slope.

Now, use the Point-Slope form:

y-y1=m(x-x1)

y-3=2(x-(-2)

y-3=2x+4

y=2x+4+3

y=2x+7

Therefore, the equation of the line is: y=2x+7

Hope this helps!

Two computers just scanned for viruses at the same time. Computer A runs a virus scan every 3.75 days. Computer B runs a virus scan every 4.5 days. How long will it be until both computers runs a virus scan at the same time again?

Answers

Answer:

Step-by-step explanation:

List out multiples for both 3.75 and 4.5

3.75+3.75=7.5

7.5+3.75=11.25

11.25+3.75=15

15+3.75=18.75

18.75+3.75=22.5

4.5+4.5=9

9+4.5=13.5

13.5+4.5=18

18+4.5=22.5

At 22.5 days will both computers scan at the same time

If computer A runs a virus scan every 3.75 days. Computer B runs a virus scan every 4.5 days. It takes 22.5 days to be until both computers to run a virus scan at the same time again

What is an arithmetic operation?

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.

It is given that, two computers just scanned for viruses at the same time. Computer A runs a virus scan every 3.75 days. Computer B runs a virus scan every 4.5 days.

We have to add the multiples of 3.75 days for computer A as,

3.75+3.75=7.5

7.5+3.75=11.25

11.25+3.75=15

15+3.75=18.75

18.75+3.75=22.5

For computer B

4.5+4.5=9

9+4.5=13.5

13.5+4.5=18

18+4.5=22.5

22.5 is the common multiple for both cases,

Thus, if computer A runs a virus scan every 3.75 days. Computer B runs a virus scan every 4.5 days. It takes 22.5 days to be until both computers to run a virus scan at the same time again.

Hi! So in equations similar to this, you will need to use PEMDAS.

P - Parenthesis

E - Exponents

M - Multiplication

D - Division

A - Addition

S - Subtraction

Now that you know this, reevaluate your equation.

7-2x8+1

Firstly, you must multiply -2 and 8. Leaving you with -16.

7-16+1

Next, subtract 16 from 7.

-9 + 1

Finally, add -9 and 1.

-8

Your final answer is -8.

A) Translation

Step-by-step explanation:

Since the triangle didn't turn at all it isn't rotation.

Since the triangle wasn't flipped over a line it isn't reflection.

Since the size of the triangle wasn't changed it isn't dilation.

Answers

Answer:

Step-by-step explanation:

uhh no explanation cuz logic

The 3rd power of the term 5y without exponents is 125.y.y.y

What is power of any number?

If a is any positive number and n is its power , then aⁿ means a is multiplied by itself n times

The given term is 5y,

To find the third power of 5y,

The cube of 5y = (5y)³

To write the 3rd power without exponents,

Simplify the term (5y)³.

(5y)³ = 5y x 5y x 5y

       = 125 y.y.y

The required 3rd power of 5y without exponents is 125.y.y.y.

2 to the 5 = 2x2x2x2x2 = 32

8 x 32 = 256 (all the solutions are factors of 2048).

2 to the 8 = 2x2x2x2x2x2x2x2 = 256 again

256 / 256 = 1
