Answer:

At least two of the lateral faces are congruent.

Step-by-step explanation:

Because the words "at least" are used this means that at a minimum 2 of the faces are congruent. Because the base is in the shape of a triangle, this will definitely be true.

hope this helps:)

Answer:

I believe that B is the correct answer!

Step-by-step explanation:

The (x+5) can cancel

Then in the numerator (x^2-25) can be factored into (x-5)(x+5) through difference of squares.

Then in the denominator the (x-5)^2 can be stretched out to (x-5)(x-5)

Lastly the (x-5) on the top and bottom will cancel resulting in result B

I hope this helped!

According to the Americans with Disabilities Act, a ramp can rise no more than 1 ft for every 12 ft of horizontal distance. What

taurus [48]

Answer:

A. 4.8°

Step-by-step explanation:

We have that,

The horizontal distance for the ramp = 12 feet.

Maximum height of the ramp = 1 feet.

So, we get that the value of the angle 'x' made by the ramp with the ground is given by,

$\tan x=\frac{perpendicular}{base}$

i.e. $\tan x=\frac{1}{12}$

i.e. $\tan x=0.0833$

i.e. $x=\arctan 0.0833$

i.e. x = 4.8°

Thus, the maximum angle made by the ramp with the ground is 4.8°.

Paralell to y=4x-6 through (12,10)

stiks02 [169]

ANSWER

The line that is parallel to $y=4x-6$ through $(12,10)$ is $y=2x-14$ .

EXPLANATION

The equation that is parallel to the line $y=4x-6$ has a slope that is equal to the slope of this line.

By comparing this equation to the general slope intercept form,

$y=mx+c$ ,this line has slope $m=2$ .

Hence the line parallel to this line also has slope $m=2$ .

Let $y=mx+b$ be the equation of the line parallel to the line

$y=4x-6$

We can substitute $m=2$ to obtain;

$y=2x+b$

If the line passes through the point $(12,10)$ ,then this point must satisfy its equation.

We substitute $x=12$ and $y=10$ to obtain;

$10=2(12)+b$

We this equation for $b$ .

$\Rightarrow 10=24+b$

$\Rightarrow 10-24=b$

$\Rightarrow -14=b$

We substitute this value of $b=-14$ in to $y=2x+b$ to get;

$y=2x+-14$ .

Hence the equation of the line that is parallel to $y=4x-6$ through $(12,10)$ is $y=2x-14$ .

A triangle has an area of 64 square feet. If the height of the triangle is 8 feet more than its base, x, what are its height and

Nitella [24]

Answer:

8 feet

Step-by-step explanation:

Given data

Area= 64 square feet

Base= x feet

Height= x+8 feet

The expression for the area

A= 1/2b*h

substitute

64= 1/2*x*(x+8)

64= 1/2*x^2+8x

64= (x^2+8x)/2

cross multiply

64*2= x^2+8x

128= x^2+8x

rearrange

x^2+8x-128= 0

using the quadratic formula

a=1

b=8

c=-128

x= -b±√b^2-4ac/2a

x= -1±√8^2-4*1*-128/2*1

simplifying

x= 8

x=-16

Hence the height of the base is

h= 8 feet
