Let A be a 4 x 5 matrix and Let B be a 4 x 4 matrix. Suppose you were asked to multiply matrix A times matrix B. When multiplied the resulting solution of multiplying matrix A times matrix B will be a 4x 4 matrix.
a. True
b. False
Answer:
b. false
Step-by-step explanation:
when multiplying matrixes the number of columns of the first matrix must be equal as the number of rows of the second matrix, and since here matrix A has 4 columns but matrix B has 5 rows they can't be multiplied

Answer: 15:13

What were the total expenses of the Estrada family last month?
Pie charts are used to show the relationship between data in a circle. The total expenses of the Estrada family last month are: $2287.5
Given that:
[tex]Clothing = \$366[/tex]
From the Pie chart, 13% of the total expenses were spent on clothing.
This means that
[tex]13\% \times Total = Clothing[/tex]
So, we have:
[tex]13\% \times Total = \$366[/tex]
Divide both sides by 13%
[tex]Total = \$366 \div 16\%[/tex]
[tex]Total = \$2287.5[/tex]
Hence, the total expenses are: $2287.5

========================================================
Explanation:
Let's say we had a circle with radius 5
It's area would be
A = pi*r^2
A = pi*5^2
A = 25pi
Now let's increase this by a factor of 4. We'll multiply the area by 4
new area = 4*(old area) = 4*(25pi) = 100pi
Now, we'll use this area value to find what the radius must be
A = pi*r^2
100pi = pi*r^2
100 = r^2
r^2 = 100
r = sqrt(100)
r = 10
The old radius r = 5 jumps to r = 10 so that the area quadruples.
We see that the radius has doubled. This must also mean the perimeter around the circle, aka circumference, must also have doubled.
C = 2*pi*r = 2*pi*5 = 10pi = old circumference
C = 2*pi*r = 2*pi*10 = 20pi = new circumference
This is directly because r has been doubled
-------------
Here's one way to think of why this works:
Consider a square of side lengths 3. It's area is 3*3 = 9.
If we double the sides, then we have a 6 by 6 square of area 6*6 = 36.
Note the jump from 9 to 36 is "times 4". This multiplier 4 is from each side doubling and we have 2*2 = 4.
If you were to triple each side, then the area multiplier would be 3*3 = 9
Multiplying each side by k leads to an area multiplier of k^2.

B. f(x) has two real zeros at -4 and -2 because the
graph of the function has intercepts at (-4,0) and (0,
-2).
C. f(x) has no real zeros because the graph of the

or x >
A
Answer:
x ≤ 11/6 or x > 11/3
Step-by-step explanation:
6x - 2 ≤ 9 or 4 + 3x > 15
6x ≤ 11 or 3x > 11
x ≤ 11/6 or x > 11/3
The given inequality is simplified as x≤11/6 or x>4.
What are inequalities?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
Given that, 6x-2≤9 or 4+3x>15.
Here, 6x-2≤9
Add 2 on both the sides of an inequality, we get
6x≤11
Divide 6 on both the sides of an inequality, we get
x≤11/6
Now, 4+3x>15
Subtract 4 on both the sides of an inequality, we get
3x>12
Divide 3 on both the sides of an inequality, we get
x>4
So, x≤11/6 or x>4
Therefore, the given inequality is simplified as x≤11/6 or x>4.

for f(x) evaluate each of the following:
a. f(0)
b. f(6)
show all your work
Answer:
Step-by-step explanation:
a)
f(0) is just the function f(x) evaluated at 0, meaning we need to plug in 0 to the function.
What piece of this function should we plug 0 in? Well, because 0 is less than 5, plug it into the first piece.
so f(0) = 0 + 4 = 5
b)
By similar reasoning:
f(6) = 8
because 5 <= 6 < 7

find the distance between the two points rounding to the nearest tenth (4,0) and (0,9)
Answer:
[tex]\boxed {\boxed {\sf 9.8}}[/tex]
Step-by-step explanation:
We are asked to find the distance between two points. We will calculate the distance using the following formula;
[tex]d= \sqrt {(x_2-x_1)^2+(y_2-y_1)^2[/tex]
In this formula, (x₁ , y₁) and (x₂ , y₂) are the 2 points. We are given the points (4,0) and (0,9). If we match the value and the corresponding variable, we see that:
x₁= 4 y₁= 0 x₂= 0 y₂= 9Substitute the values into the formula.
[tex]{d= \sqrt {(0-4)^2+(9-0)^2[/tex]
Solve inside the parentheses.
(0-4)= -4 (9-0)= 9[tex]d=\sqrt{(-4)^2+ (9)^2[/tex]
Solve the exponents. Remember that squaring a number is the same as multiplying it by itself.
(-4)²= -4*-4= 16 (9)²= 9*9= 81[tex]d= \sqrt{(16)+(81)[/tex]
Add.
[tex]d= \sqrt{97[/tex]
Take the square root of the number.
[tex]d=9.848857802[/tex]
Round to the nearest tenth. The 4 in the hundredth place tells us to leave the 8 in the tenth place.
[tex]d\approx 9.8[/tex]
The distance between the two points (4,0) and (0,9) is approximately 9.8
Two angles are supplementary. The measure of the larger angle is 36 more than the measure of the smaller angle. Find their measures.
the answers are 72° and 108° but I need help showing my work
x = smaller angle
x+36 = larger angle, since its 36 degrees more than the smaller angle
The two angles x and x+36 must add to 180 if they are to be supplementary (aka form a straight line)
So this means we can say the following:
(smaller)+(larger) = 180
(x) + (x+36) = 180
2x+36 = 180
2x = 180-36
2x = 144
x = 144/2
x = 72 is the smaller angle
x+36 = 72+36 = 108 is the larger angle
As a check:
smaller+larger = 72+108 = 180
which shows they are supplementary and it confirms our answers
Step-by-step explanation:
let the smaller angle be x
then the measure of larger angle will be x+36
x+x+36=180°(being supplementary angle)
2x+36=180°
2x=180°-36
2x=144°
x=144°/2
x=72°
now,
the larger angle x+36 = 72+36=108°
