Step-by-step explanation:

1. to make up the equations of lines PQ and RS:

(PQ)  [tex]\frac{x-0}{2} =\frac{y+9}{1}; \ \frac{x}{2}=\frac{y+9}{1};[/tex]

(RS)  [tex]\frac{x-1}{-2}=\frac{y-4}{1}; \ \frac{x-1}{-2}=\frac{y-4}{1};[/tex]

2. to write the pointed verctors of PQ and RS:

for PQ it is p=(2;1); for RS it is r=(-2;1).

3. according to the pointed vectors it is clear, the given lines are not perpendicular [2*(-2)+1*1≠0].

Step-by-step explanation:

Given is the quadratic equation

It has the maximum height at its vertex, x-coordinate of which is calculated by the formula:

Calculating the highest point:

9:16 -> 3:8

How?

Divide each side by 2 (the GCF).

10:12 -> 5:6

How?

Divide each side by 2 (the GCF).

20:16 -> 5:4

How?

Divide each side by 4 (the GCF).

24:36 -> 2:3

How?

Divide each side by 12 (the GCF).

Answer:

9: 16 for 9 to 16; is the simplest form for 9/16 cuz nothing can go into 9 and 16

5 : 6 for 10 to 12; cuz 10 divided by 2 is 5 and 12 divided by 2 is 6!

5: 4 for 20 to 16; cuz 20 divded by 4 is 5 and 16 divded by 4 is 4

lastly is 2:3 for 24 to 36; why? well it's ciz 24 divided by 12 is 2 and 36 divedde by 12 is 3

hope this helps and pls don't delate my answer!

Answer:

The right answer is A

Step-by-step explanation:

The value of the exponential equation is y = 3ˣ and the graph is plotted

When you raise a quotient to a power you raise both the numerator and the denominator to the power. When you raise a number to a zero power you'll always get 1. Negative exponents are the reciprocals of the positive exponents.

The different Laws of exponents are:

mᵃ×mᵇ = mᵃ⁺ᵇ

mᵃ / mᵇ = mᵃ⁻ᵇ

( mᵃ )ᵇ = mᵃᵇ

mᵃ / nᵃ = ( m / n )ᵃ

m⁰ = 1

m⁻ᵃ = ( 1 / mᵃ )

Given data ,

Let the exponential equation be represented as A

Now , the value of A is

y = 3ˣ   be equation (1)

Now , the y intercept of the equation is when x = 0

So , when x = 0

y = 3⁰

y = 1

Now , when y₁ = 3^1.2

The value of y₁ = 3.7

Therefore , the y intercept of the equation is 1 and the graph is plotted

Hence , the exponential equation is y = 3ˣ

Answer:

B must travel at the rate of 10 miles per hour.

The speed at which B should travel is 10 mph

What is Speed?

Speed is defined as the rate of change of position of an object in any direction. Speed is measured as the ratio of distance to the time in which the distance was covered. Speed is a scalar quantity as it has only direction and no magnitude

Speed = Distance / Time

Given data ,

Let the distance between A and B be D = 150 miles

Now , the equation will be

The speed of A = 20 mph

Let the speed of B be = B

The time required T = 5 hours

From the equation , Distance = Speed x Time

Substituting the values in the equation , we get

150 = ( A x T ) + ( B x T )

20 x 5 + ( B x 5 ) = 150

On simplifying the equation , we get

100 + 5B = 150

Subtracting 50 on both sides of the equation , we get

5B = 50

Divide by 5 on both sides of the equation , we get

B = 10 mph

Therefore , the value of B is 10 mph

Hence , the speed of B is 10 mph

Answer:

Mick can run farther in less time if that's the question

Step-by-step explanation:

Mick's speed is faster.

Speed is the ratio of distance and time.

It shows how fast an object is moving at a given time.

We have,

Carlos can run 5 miles in 45 minutes.

45 minutes = 45/60 = 0.75 hours

Speed.

= 5/0.75

= 6.66 miles per hour.

Kelly can run 10 miles in 80 minutes.

80 minutes = 1.33 hours

Speed.

= 10/1.33

= 7.5 miles per hour.

Mick can run 30 miles in 170 minutes

170 minutes = 2.8 hours

Speed.

= 30/2.8

= 10.7 miles per hour

Thus,

Mick's speed is faster.
