I can Multiply a 4x4 matrix by a 4x3 matrix. The resulting matrix will be a?

If Angle 1 and Angle 2 are complementary angles and if the measure of Angle 1 is 20° more than the measure of Angle 2, determine

Ratling [72]

A) Ang 1 + Ang 2 = 90
B) Ang 1 = Ang 2 + 20
B) Ang 1 -Ang 2 = 20 then adding this to equation A produces
2 Ang1= 110
Ang 1 = 55 degrees
Ang 2 =35 degrees

Problem 7

Time is always an independent variable because time marches on doing its own thing without depending on external forces, or other people/things. Instead, other variables depend on time. In this case, the distance d depends on the independent variable t for time.

If the time goes up by 1 hour, then the distance variable goes up by 3 miles. In short, that tells us his speed is 3 mph.

Answer: Choice A) independent = time; dependent = distance

=================================

Problem 8

Everywhere you see an x, replace it with 9. Then use PEMDAS to simplify

f(x) = 5x - 9

f(9) = 5(9) - 9 ... x replaced with 9

f(9) = 45 - 9

f(9) = 36

Answer: 36

Someone please help me with this math problem?

Answer:

The length of the shortest side of the triangle is 10 units.

Step-by-step explanation:

Let a be the shortest side of the isosceles triangle and b be the two congruent sides.

The congruent sides b are each one unit longer than the shortest side. Hence:

$b=a+1$

The perimeter of the isosceles triangle is given by:

$\displaystyle P_{\Delta}=b+b+a=2b+a$

This is equivalent to the perimeter of a square whose side lengths are two units shorter than the shortest side of the triangle. Let the side length of the square be s. Hence:

$s=a-2$
