the slope is 2 over 3 because you ride 2 up and 3 to the right to get to the next dot and the y intercept is 3 because that's where the line intercepts the y axis.

Answer:

10 seconds.

Step-by-step explanation:

The velocity at which they are approaching each other = 59 + 41 = 1000 km per second.

Velocity = distance  / time

So time =  distance / velocity

= 1000 / 100

= 10 seconds.

10 seconds long does it take for them to collide.

Velocity exists as the measurement of the amount of distance an object covers in a given amount of time. Here's a term equation that describes the connection between distance, velocity, and time: Velocity equals distance traveled divided by the time it brings to get there.

The velocity at which they exist approaching each other = 59 + 41

= 1000 km per second.

Velocity = distance / time

So, time = distance / velocity

= 1000 / 100

= 10 seconds.

Therefore, 10 seconds long does it take for them to collide.

Answer: Undefined

Step-by-step explanation: Since there is no change in x, and it is a horizontal line, that means that the denominator is zero. Dividing anything with the denominator being 0 will always be undefined (Not to be confused with the numerator, which is just dividing by 0, thus giving you 0.) That means that our answer will be undefined.

Answer: x=40

Step-by-step explanation:

The solution to log (25x) = 3 is 40. This is calculated by using log rules.

A function that has log terms is said to be a logarithmic function.

Some of the rules for solving log functions are as follows:

Given that,

log (25x) =3

Using basic form [tex]log_b(m)=n[/tex] ⇒ [tex]m=b^n[/tex]

Here base b=10, m=25x and n=3

Then,

log (25x) =3

⇒ [tex]25x = 10^3[/tex]

⇒ 25x = 1000

⇒ x = 1000/25

∴ x = 40.

Hence the solution of the given function is 40.

Step-by-step explanation:

6 donuts. He repacked 6 donuts into each box .

Mr. Terence had 18 boxes containing 36 donuts each, that means:

Total donuts = n° boxes*n° donuts

Total donuts = 18*36 = 648

He had in total 648 donuts.

He sold 162 donuts and repacked the rest into 81 boxes. Then:

Rest donuts = Total donuts - sold donuts

Rest donuts = 648 - 162 = 486

The rest donuts are 486 donuts.

He repacked the rest into 81 boxes, then:

n° donuts (each box) = Rest donuts/n° boxes

n° donuts (each box) = 486/81 = 6

The number of donuts that he put in each box is 6 donuts.

For the first answer (A)

The area of the base is the area of the 8 by 4 rectangle, minus the missing 2 by 2 square in the top-right.  This is 8*4-2*2=32-4=28 square centimeters.

For the second answer (B)

The volume of the prism is the base area multiplied by the height, or 28*10=280 cubic centimeters.

Answer:

Area = 28 cm² and Volume = 280 cm³

Step-by-step explanation:

A. Area of the base of the prism = Area of rectangle with dimensions 4 × 8 cm. minus area of a rectangle with dimensions 2×2 cm.

Area = 4 × 8 - 2 × 2

       = 32 - 4 = 28 cm²

B. Volume of the given prism = Volume of full prism with dimensions 10 × 4 × 8 cm. minus volume of small prism (missing) having dimensions 2×2×10 cm.

Volume = 10 × 4 × 8 - 2 × 2 × 10

             = 320 - 40

            = 280 cm³

Area = 28 cm² and Volume = 280 cm³

Answer:

D

Step-by-step explanation:

We need to understand the meaning of slope. The slope means the rate of change of y with every unit change of x.

In our case, it will be rate of change of sales increase (%) with respect to unit change of discount(%).

The formula for slope is the change in y divided by change in x.

From the 2 points given, we can say that slope is:

[tex]\frac{62-32}{20-10}=\frac{30}{10}=\frac{3}{1}[/tex]

This means "as discount increases 1%, sales increase by 3%". Option D is right.

Last option: 63

Step-by-step explanation:

You need to observe and analize the triangle XWZ provided in the image attached.

You can observe that the lenght of the side XW of the triangle XWZ is congruent to the lenght of the side ZW. This means that the lenght of the side XW and the lenght of the side ZW are equal.

Therefore, if the measure of the angle ∠X is 63, then the measure of the angle ∠YZW is 63:

[tex]m\angle YZW=m\angle X[/tex]

[tex]m\angle YZW=63[/tex]

Step-by-step explanation:

It's 32, just follow the row when g=13.

Answer: We want to know f( g (13) ), here g(13) is just a number, so you are evaluating f in a number, first we need to know the value of g(13). Looking in the diagram you can see that g(13) = 16.

So f(g(13)) = f(16)

Also, looking in the diagram you can see that f(16) = 32

So, f ( g (32) ) = 32

Answer:

x = 4

Step-by-step explanation:

Using the 90-60-30 theorem, the hypotenuse is equal to 2a, so a = 4 sqrt(2). The shortest leg is therefore 4 sqrt(2). Using this, to find x, plug it into the smaller triangle. The hypotenuse of the smaller triangle is therefore 4 sqrt(2). Using the 45-45-90 theorem, 4 sqrt(2) = x sqrt(2), so x = 4. This is because there are two sqrt(2)'s', so taking that out of the equation leaves x = 4.

Hope this helps!

Answer:

The direction of 5c + 4d is approximately 19.0° clockwise with

the positive part of x-axis

Step-by-step explanation:

* Lets talk about the direction of a vector

- If the vector is (x , y), then  

# Its magnitude is √(x² + y²)

# Its direction is tan^-1 (y/x)

- The direction is the angle between the positive part of x-axis and  

  the vector

* Lets solve the problem

∵ c = (2.4 , 0.45) and d = (7 , -4)

- To find 5c + 4d , multiply the two coordinates of c by 5 and the two

  coordinates of d by 4

# Multiply c by 5

∴ 5c = [5(2.4) , 5(0.45)]

∴ 5c = (12 , 2.25)

# Multiply d by 4

∴ 4d = [4(7) , 4(-4)]

∴ 4d = (28 , -16)

- Lets add 5c and 4d

∴ 5c + 4d = (12 , 2.25) + (28 , -16)  

∴ 5c + 4d = [(12 + 28) , (2.25 + -16)]

∴ 5c + 4d = (40 , -13.75)

- The vector is in the 4th quadrant because the x-coordinate is

 positive and the y-coordinate is negative

* Find the direction of 5c + 4d

∵ The direction is tan^-1 (y/x)

∴ The direction is tan^-1 (-13.75/40) = -18.97°

* The direction of 5c + 4d is approximately 19.0° clockwise with

 the positive part of x-axis

Answer:

Step-by-step explanation:

What do we know about that prism?

It's a rectangular prism with a square base.

Height: y (from question)

base length: x (from question)

base width: x (from question, since it's a square base).

Total volume: 150 cu inches

The question lacks a relationship between x and y the "is __ times", but we can see from the answer choices that they all show a constant relationship:

y = 1.5 x  

The volume of a prism is obtained by  multiplying the lengths of its 3 dimensions: V = length * width * height.  In our case, we then have

150 = x * x *  y

then we replace y by its x-expressed equivalent:

150 = x * x * (1.5x) = 1.5x³

then we isolate x³ by dividing each side by 1.5

x³ = 100, we do the cubic root on each side

x = 4.64

So, answer is D. x = 4.6 and y = 6.9

If you you 4.64 * 4.64 * 6.96 = you get 149.8, which is very close to 150.

The answer would be D) $180,000 in bank A, $240,000 in bank B, $240,000 in bank C.

Step-by-step explanation:

You can immediately eliminate A, B and C because the question clearly states that the limit per bank is $250,000.

Answer:

D. $180,000 in bank A, $240,000 in bank B, $240,000 in bank C

Step-by-step explanation:

She needs to deposit less than $250,000 in each bank in order to be able to have that sum of money insured, in this case she could deposit it this way:

$250,000

$250,000

$160,000

But that could be too risky and too on the verge of not being accepted, you she just takes $10,000 out of every $250,000 deposits to make them $240,00, and add it to the $160,000 deposit, so she is left with three deposits of:

$240,000

$240,000

$180,000

And with this she makes sure all of her deposits are insured by staying below the $250,000 limit.

Step-by-step explanation:

Area of the shaded region = area of the circle-area of the minor segment.

The area of the minor segment is calculated as follows.

Area= Area of sector - area of the triangle bound by the radii.

=∅/360πr²-1/2r²sin∅, where r is the radius of the circle and ∅ the obtuse angle bound by the radii.

=130/360×π×11.1²-1/2×11.1²sin130

=93.43m²

Area of the whole circle =πr²

=π×11.1²

=387.08m²

Area of the shaded region

=387.08m²-93.43m²

=293.65m²

≅293.7m² to the nearest tenth.
