Answer:

see below

Step-by-step explanation:

Because two sides are congruent, the triangle in the diagram is isosceles which means that angle c = angle e because of the Base Angles Theorem. We know that angle c = 63 degrees because we see that it's vertical to a 63 degree angle, and vertical angles. Since angle c = angle e, angle e = 63 degrees. Since angles e and b form a linear pair, they are supplementary, meaning that they add up to 180 degrees which means that angle b = 180 - 63 = 117 degrees. To find angle d, we notice that d and c are alternate interior angles, and since these angles are congruent in parallel lines, angle d = 63 degrees as well. To find angle a, we know that the sum of angles in a triangle is 180 degrees so angle a = 180 - 63 - 63 = 54 degrees.

What is the length of LM if L(3,4) and M(1,-2)? Round to the nearest tenth.

kari74 [83]

Answer:

We conclude that the length of LM if L(3,4) and M(1,-2) will be:

$d = 6.3$

Hence, option D is correct.

Step-by-step explanation:

Given

L(3,4)

M(1,-2)

Determining the length of LM

(x₁, y₁) = (3, 4)

(x₂, y₂) = (1, -2)

The length of the distance between (x₁, y₁) and (x₂, y₂) can be determined using the formula

$d=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}$

substituting (x₁, y₁) = (3, 4) and (x₂, y₂) = (1, -2)

$=\sqrt{\left(1-3\right)^2+\left(-2-4\right)^2}$

$=\sqrt{2^2+6^2}$

$=\sqrt{4+36}$

$=\sqrt{40}$

$=\sqrt{4\times 10}$

$=\sqrt{2^2\times \:10}$

$=2\sqrt{10}$

$=6.3$

Therefore, we conclude that the length of LM if L(3,4) and M(1,-2) will be:

$d = 6.3$

Hence, option D is correct.

H(n)=-2n^2+4; find h(4)

IceJOKER [234]

Answer: h(4) = 36

Step-by-step explanation:

All you have to do is plug in 4 to the equation.

So, h(4) = 2(4)^2+4

=2(16)+4

=32+4

=36

Which function has the smallest minimum? (5 points)

Andrej [43]

f(x) has the smallest minimum. The minimum value of f(x) is -3

The largest sin(x) can get is 1.
This applies to sin(2x-pi) as well. So f(x) is as small as -5*(1)+2 = -5+2 = -3.
You can see this each time the red curve bottoms out at y = -3.

The smallest that g(x) can get is y = -2 as shown at the vertex (3,-2)

The smallest that h(x) can get is y = 3 as shown by the point (1,3)

See the attachment for a visual comparison of the three functions.
