Screen measures 30 cm wide n 22 cm high what is the diagonal measure of the screen

1 answer:

8 0

I think you'd use the pythagoran theorem for this (a squared + b squared = c squared). So 30 squared plus 22 squared equals the diagonal measure squared. This is 900 + 484 = c squared. That's 1384. The square root of that is 37.

Two factors of –48 have a difference of 19. The factor with a greater absolute value is positive. What is the sum of the factors

statuscvo [17]

Answer:

Step-by-step explanation:

Two factors of -48... that means two numbers which multiplied together give a result of -48, like -6 and 8 for example.

The difference of those two factors is -19. There not that many possible factors for -48, so if we list them we'll be able to spot a pair with a difference of 19.

A first list of factors for -48 is: -1 and 48, -2 and 24, -3 and 16, -4 and 12, -6 and 8.

We can create another list by inverting the signs: 1 and -48, 2 and -24, 3 and -16, 4 and -12, 6 and -8.

The question says the difference of the two factors is 19... can you spot in each list a pair of factors having a difference of 19? I see -3 and 16 and also 3 and -16.

The question also say the one of the greatest absolute value is positive... so that means it's a pair with +16, not -16.

The pair of factors we're looking for is then -3 and 16. They are factors of -18, they have a difference of 19, and the one with the greatest absolute value is positive.

The sum of -3 and 16 is 13.

Sliva [168]

Answer:

Step-by-step explanation:

steps are below

step 1

y^3-8y^2+19y=12 equation

step 2

y^3-8y2+19y(-12)=12(-12) minus 12 from both sides

y^3-8y^2+19y-12=0

step 3

(y-1)(y-3)(y-4)=0 add brackets

step 4

(y-1)(y-3)(y-4)=0 factor

step 5

y-1=0 or y−3=0 or y-4=0 set them equal

Answer:

y=1 or y=3 or y=4

What is the value of y circle the correct answer 62y = 434 1. Y=7 2. Y=5

MrRa [10]

When we solve for y, we want to isolate y by itself. To do so in this equation, we can divide both sides of the equation by 62...

y = 434/62 = 7
