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

Answer:

Choice a. [tex]35[/tex]

Step-by-step explanation:

Note that [tex]i=(1,0)[/tex] and [tex]j=(0,1)[/tex], so

[tex]C=2A-B=2(6i-8j)-(-16i+5j)=12i-16j+16i-5j=28i-21j=(28,-21)[/tex]

Now the magnitude of a vector [tex](x,y)[/tex] is [tex]\sqrt{x^2+y^2}[/tex], thus the magnitude of [tex]C[/tex] is

[tex]\sqrt{28^2+(-21)^2}=\sqrt{784+441}=\sqrt{1225}=35[/tex]

Answer:

[tex]x = \frac{2}{65} [/tex]

Step-by-step explanation:

[tex]19 = - 4 + \frac{2}{5x} + 10[/tex]

[tex]19 = 6 + \frac{2}{5x} [/tex]

[tex] - \frac{2}{5x} = 6 - 19[/tex]

[tex] - \frac{2}{5x} = - 13[/tex]

[tex]2 = 65x[/tex]

[tex]x = \frac{2}{65} [/tex]

Answer:

It is 9n - 7p + 5q

Step-by-step explanation:

Perimeter formular:

[tex]perimeter = (side + side + side)[/tex]

substitute:

[tex]p = \{(7n - 2p) + (2n + 4q) + (q - 5p) \} \\ [/tex]

group like terms together:

[tex] = (7n + 2n) + ( - 2p - 5p) + (4q + q) \\ = 9n - 7p + 5q[/tex]

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:

Substitute the values into the formula.

[tex]{d= \sqrt {(0-4)^2+(9-0)^2[/tex]

Solve inside the parentheses.

[tex]d=\sqrt{(-4)^2+ (9)^2[/tex]

Solve the exponents. Remember that squaring a number is the same as multiplying it by itself.

[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

Answer: Yes it is.

Answer:

answer must be 9

Step-by-step explanation:

6/2×3

3×3

9 ans

Answer: 9

Step-by-step explanation:

( 6/2) = 3

( 1+2) = 3

3*3=9

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°

Answer:

its very blury im sooooo sorry

Step-by-step explanation:

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.

Answer:

I agree with the student's answer. "x" cannot be -2 because then it would make -20 which is not equal to 20:

5(-2)(2) = ?

-10 x 2 = ?

? = -20

-20 ≠ 20

Step-by-step explanation:

Justificaiton:

5(x)(2) = 20

10(x) = 20

10/10(x) = 20/10

x = 2

Second Justification:

5(x)(2) = 20

5/5(x)(2) = 20/5

2x = 4

2x/2 = 4/2

x = 2
