Answers

Answer:

y = 3/4*4ˣ

Step-by-step explanation:

The function is:

y = abˣ

Substitute the values from the given points and solve for b:

48 = ab³768 = ab⁵

Divide the second equation by the first one:

768/48 = ab⁵/ab³b² = 16b = 4

Find a using the first equation:

48 = a*4³a = 48/64a = 3/4

The function is:

y = 3/4*4ˣ

Answer:

AB = 51

BC = 50

AC = 42

PQ = 42

QR = 42

PR = 59

Step-by-step explanation:

Perimeter of ∆ ABC = Perimeter of ∆ PQR

3x + 9 + 3x + 8 + 3x = 3x + 3x + 4x + 3

9x + 17 = 10x + 3

17 - 3 = 10x - 9x

14 = x

.: x = 14

AB = 3x +9 = 3×14+9 = 42+9 = 51

BC = 3x +8 = 3×14+8 = 42+8 = 50

AC = 3x = 3×14 = 42

PQ = 3x = 3×14 = 42

QR = 3x = 3×14 = 42

PR = 4x +3 = 4×14+3 = 56+3 = 59

Answers

Answer: (x,y) -> (x,-y)

Step-by-step explanation:

If you take any point, for example (-1,1) from the blue shape, you have to multiply the y value by -1 to get to (-1,-1) for the red shape. You can test it out with any point on the two figures.

Also, by looking at it, you can see that it is a reflection over the x axis and a reflection over the x axis always just multiplies the y value by -1.

Answers

Answer:

slope =[tex]-\frac{2}{3}[/tex]

Step-by-step explanation:

Use the slope formula [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex] to find the slope, or [tex]m[/tex]. The [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of one point, and the [tex]x_2[/tex] and [tex]y_2[/tex] represent the x and y values of another point. So, substitute the x and y values of the points (14, -18) and (5, -12) into the formula and solve:

[tex]m = \frac{(-12)-(-18)}{(5)-(14)}\\m = \frac{-12+18}{5-14}\\m = \frac{6}{-9} \\m = -\frac{2}{3}[/tex]

Thus, the slope is [tex]-\frac{2}{3}[/tex].

Answers

Answer:

752 ft

Step-by-step explanation:

Assuming t represents time, and the time we are trying to find is how high the rockets go after 1.5 seconds, we must take the equation and put 1.5 in wherever t occurs, this looks like:

-16(1.5)²+64(1.5)+80

Step-by-step explanation:

The speed of the train is 320 miles per hour.

What is speed?

Speed is the ratio of the given distance and time.

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

The formula is Distance / Time.

We can find the distance or time when the required values is given using this formula.

We have,

The speed of the TGV train can be calculated using the formula:

Speed = distance/time

where distance is given in miles and time is given in hours.

In this case,

The distance traveled by train is 800 miles, and the time taken to travel this distance is 2.5 hours.

Substituting these values into the formula, we get:

Speed = 800 miles / 2.5 hours

Simplifying the expression on the right-hand side, we get.

Speed = 320 miles per hour

Therefore,

The speed is 320 miles per hour.

Quadrilateral MNPQ is shown.

Trapezoid M N P Q is divided into 4 triangles by N Q and M P, which intersect at point R inside the trapezoid. N P is parallel to M Q and M N is congruent to Q P. Angle N M P is 30 degrees and angle P M Q is 32 degrees. Segment Q R equals 4.1.

If MP = 5.9, what is RN?

(Round your answer to the nearest tenth. Write NA if there is not enough information given.)

Answers

Answer:4.1

Step-by-step explanation:

In the Quadrilateral MNPQ, if MP = 5.9, then RN = 1.8.

What is a trapezoid?

An open, flat object with four straight sides and one set of parallel sides is referred to as a trapezoid or trapezium. A trapezium's non-parallel sides are referred to as the legs, while its parallel sides are referred to as the bases.

Given:

Quadrilateral MNPQ is shown.

Trapezoid MNPQ is divided into 4 triangles by NQ and MP.

MQ is parallel to NP.

That means, MQ and NP always at the equal distance.

MN ≅ QP

So,

MP = QN

Now,

QN = QR + RN and QR = 4.1:

MP = QN

5.9 = 4.1 + RN

Then RN = 5.9 - 4.1 = 1.8

Therefore, the value of RN is 1.8.
