base=x

leg=3x-2

3x-2+3x-2+x=45

7x-4=45

7x=49

x=7

leg=3x+2=3(7)-2=19

10^12 in standard number is 1000000000000

<h3>How to convert the number?</h3>

The number is given as:

$10^{12$

Expand the expression

$10^{12} = 10 * 10 * 10 * 10 *10 * 10 * 10 * 10*10 * 10 * 10 * 10$

Evaluate the product

$10^{12} = 1000000000000$

Hence, 10^12 in standard number is 1000000000000

Find the equation of a circle in standard form that is tangent to the line x = -3 at (-3, 5) and also tangent to the line x = 9.

Sedaia [141]

Answer:

(x -3)² +(y -5)² = 36

Step-by-step explanation:

The center is on the vertical line halfway between the given vertical lines, so is at x=3. It is also on the horizontal line through the point (-3, 5), so is at y=5. The center is 9-3=6 from either tangent line, so this is the radius.

For center (h, k) and radius r, the circle's equation is ...

(x -h)² +(y -k)² = r²

For (h, k) = (3, 5) and r=6, the equation is ...

(x -3)² +(y -5)² = 36 . . . . . . . . does not match any choice written here

Kawika is a woodworker, and he carves a block in the shape of a rectangular prism. What is the total surface area of the block

slavikrds [6]

Surface Area of a Right Traingular Prism is = bh + L(S1 + S2 + h)

from the question given

h = 5,

S1 = 12 = b

S2 = 13

L =10

= bh + L(S1 + S2 + h)

= 12(5) + 10(12 + 13 + 5)

= 60 + 10(30)

=60 + 300

=360

From the shape

The Triangle side Area = 1/2 X B X H

=1/2 X12 X 5 = 30

we have two faces of the triangle = 2x 30 = 60

For the Top side = 10 X 13 = 130

for the base/floor = 12 x 10 = 120

for the back end side = 5 x 10 = 50

Total = 60 + 130 + 120 +50

=360
