Answer:

The area of the triangle is 28 square units

Step-by-step explanation:

First we have to calculate the length of the base of the triangle and the length of the height

To calculate the base we have to subtract point (-1 , 2) from point (7 , 2)

(7 , 2) - (-1 , 2) = ((7 - (-1)) , (2 - 2)) = (8 , 0)

because it has no component in y this means that the length of the base is 8

b = 8

To calculate the height we have to subtract point (-1 , 2) from point (-1 , 9)

(-1 , 9) - (-1 , 2) = (((-1) - (-1)) , (9 - 2)) = (0 , 7)

because it has no component in x this means that the length of the base is 7

h = 7

To calculate the area of a triangle we have to multiply the base by the height and then divide it by 2

a = (b * h)/2

a = (8 * 7)/2

a = 56/2

a = 28

The area of the triangle is 28 square units

At a construction job for a mansion there are 37 painters. Of these painters, 67.6% of them paint the interior of the mansion. H

Inessa05 [86]

This is a relatively easy question to answer. You want to find 67.6% OF 37 mean you need to multiply. 37*0.676≈25. There should be 25 painters painting the interior.

Find the inverse of the function y = 2x^2 + 2.

kupik [55]

Answer:

its the last one.

Step-by-step explanation:

easy way to do inverse functions:

write out equation :

y = 2 $x^{2}$ + 2

Switch the x and y:

x = 2 $y^{2}$ + 2

Solve for y :

x = 2 $y^{2}$ + 2

subtract 2 both sides

x - 2 = 2 $y^{2}$

Divide both sides by 2

$\frac{x}{2}$ - $\frac{2}{2}$ = $y^{2}$

reduce fraction and square root both sides

saw5 [17]

for the equation is, x = -4 - 5i

The solution will be, x = -4 + 5i

for the equation is, x = 4 + 5i

The solution will be, x = 4 - 5i

for the equation is, x = 5 - 4i

The solution will be, x = 5 - 4i

<h3>Quadratic equation defind as:</h3>

Any equation in algebra that can be written in proper format as where x stands for an unknown, where a, b, and c stand for known numbers, and where a 0

<h3>According to the given information:</h3>

If (a + bi) is a complex number and a quadratic equation has one solution,

The second solution to the equation will be the conjugate of the first.

Consequently, the alternative solution will take the form of (a - bi).

for the equation is, x = -4 - 5i

The solution will be, x = -4 + 5i

for the equation is, x = 4 + 5i

The solution will be, x = 4 - 5i

for the equation is, x = 5 - 4i

The solution will be, x = 5 - 4i

FINAL ROUND!! Could someone please help answer this thanks so much, please no spam, will give brainliest (homework help)

Genrish500 [490]

Answer:

a is less than or equal to 7

Step-by-step explanation:

This is the case because we can treat the less than or equal to sign as an equal sign. The only time it changes is when we divide by a negative, but we do not do that in this problem. First, you subtract 7 from both sides. That leaves us with a 4a on one side and a 28 on the other. Then, you divide both sides by four to get a is less than or equal to 7. I hope this helps!
