1. What is the value of x in the figure?
irinina [24]

Answer:

x=6\sqrt{5}\\ \\y=3\sqrt{5}\\ \\z=6

Step-by-step explanation:

The height of the right triangle drawn to the hypotenuse is geometric mean of two segments of hypotenuse, so

z^2=12\cdot 3\\ \\z^2=36\\ \\z=6

By the Pythagorean theorem,

x^2=12^2+z^2\\ \\x^2=144+6^2\\ \\x^2=144+36\\ \\x^2=180\\ \\x=6\sqrt{5}

and

y^2=z^2+3^2\\ \\y^2=6^2+9\\ \\y^2=36+9\\ \\y^2=45\\ \\y=3\sqrt{5}

fenix001 [56]
f(x) = a(x+5)^2-1

2 = a(-2+5)^2-1 \\ 9a = 3 \\ a = 3

f(x) = 3(x+5)^2-1

-HELP ANSWER-
Doss [256]

Answer:

First point: (1,0)

Second Point: (2,1)

Third Point:  (3,2)

Fourth Point: (8,7)

Step-by-step explanation:

For the first two points, you have to plot the two pairs of coordinates that are given.  After this, you have to plug the x values into the equation to get the missing y values.

For example: The third point

X= 3

Y= X - 1

Y= 3 - 1

Y=2

So this means that the third coordinate is (3,2)

Ishaan is 3 times as old as Christopher and is also 14 years older than Christopher/10088809/d7a108ae?utm_source=registration
Irina-Kira [14]
X = Ishaan
y = Christopher

3y = x
x = y + 14 Put the first equation into the second.
3y = y + 14
2y = 14
y = 7

Christopher is 7
Ishaan is 21
