Find the square root of 25x^2-40xy+16y^2​

Answers

The square root of [tex]25x^2-40xy+16y^2[/tex] is 5x - 4y.

Given that,

The quadratic equation is [tex]25x^2-40xy+16y^2[/tex].We need to find out the square root.

Based on the above information, the calculation is as follows:

[tex]= 25x^2-40xy+16y^2\\\\= (5x)^2 - (2\times 5x \times 4y) + (4y)^2\\\\= (5x - 4y)^2\\\\= \sqrt{ (5x - 4y)^2}[/tex]

= 5x - 4y

Therefore we can conclude that the square root of [tex]25x^2-40xy+16y^2[/tex] is 5x - 4y.

Tuition for one year at Tarleton University is about $14,500. McKenzie wants to attend this university and will save money each month for the next 4 years. Her father will give her $6300 for her first year of tuition, and she received a $3,000 Grant. What is the amount of money McKenzie must save per month to have enough money to pay for her first year of tuition?​

Answers

Answer:

5200

Step-by-step explanation:

You know that she needs 14,500 for her first year

she has a total of 3000+6300 so far

To find out how much she needs just take the difference

14500-(3000+6300)=5200

What does a=? b=? Angle B=?

Answers

Answer:

If you were solving the right triangle, it would be:

m∠A = 46°

m∠B = 44°

m∠C = 90°

AB = 32

BC ≈ 23

AC ≈ 24

Step-by-step explanation:

To solve this right triangle, you can use trigonometric ratios to solve for the sides. To find the angle measures:

m∠A = 46° (given)

m∠B = x

m∠C = 90° (given)

180 - (46 + 90) = x

180 - 136 = x

44 = x

m∠B = 44°

To find the side measures, you can use tangent, sine, cosine, and the Pythagorean Theorem.

Recall that:

tangent = opposite side/adjacent side

sine = opposite side/hypotenuse

cosine = adjacent side/hypotenuse

So:

sin46 = BC/32

BC = 32 (sin46)

BC ≈ 23

tan46 = BC/AC

AC = BC/tan46

AC = (23.01887361...) (tan46)

AC ≈ 24

how to change .75 to a percentage NOW

Answers

Answer:

Move the decimal place over to the left two spaces

.75--> 7.5--> 75%

and reverse

75%--> 7.5--> .75

Step-by-step explanation:

brainliest plz

Answer:

75%  

Step-by-step explanation:

"Percent" means "per 100" or "over 100". So, to convert 0.75 to percent we rewrite 0.75 in terms of "per 100" or over 100.

Multiply 0.75 by 100/100. Since 100/100 = 1, we are only multiplying by 1 and not changing the value of our number.

0.75      100        75

-------- x --------  = -------- which equals to 75%

1             100        100

write in slope-intercept form 5x-3y=-9

step by step explanation too, please.

Answers

Answer:

y = (5/3)x +3

Step-by-step explanation:

slope intercept form

Y = mx +b form

so we need to solve the given equation for y

1.  5x-3y =-9

2 . 5x -3y +3y = -9 +3y (adding both sides 3y)

3. 5x = -9 +3y

4. 5x +9 = -9 +9 + 3y (adding 9 to bot sides)

5. 5x +9 = 3y

6. (5/3)x + 9/3 = (3y)/3 ( divide both sides by 3 to get y  alone)

so, the final answer will be

y = (5/3)x +3
