Fireworks are set off from a hill 80 feet above the Mississippi. The outer
shells will fall after exploding at its maximum height. The firework's height
about the surface of the river is given by the function h(t) = -16t^2 + 64t +
80. What is the height of the rocket after 1.5 seconds?

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

solving this, we get:

-24²+96+80

576+96+80

Your answer:

what’s the equation for this table?

Answers

Answer:

y=2.5x-3

Step-by-step explanation:

first, we find the y-intercept, which is the number with a zero in the x

That would be -3

next, we find the slope

to do this, we have to take two numbers on the y side next to each other and subtract.

For this example we will use 7 and 2

7-2=5

And just to be positive, we will also do 12 and 7

12-7=5

Okay, now that we know that the number is growing by 5 every time, we know that it is now 5/2 because y is growing by 5 and x is growing by 2

Now, we make the x side grow by only 1, so to do this, we will divide both sides by two.

Now we have 5/1 or just 5

Finally, to put that into the right format, we do y=5x-3

You're Welcome

What is exponential decay?

During exponential decay, a quantity falls slowly at first before rapidly decreasing. The exponential decay formula is used to calculate population decline and can also be used to calculate half-life.

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

We have a graph shown in the picture.

As we know from the definition of exponential decay, a quantity falls slowly at first before rapidly decreasing.

From the graph given, graph fourth represents the exponential decay.

The equations 3x-2y=-14 and 3x+y=-11 are plotted on the same set of axes. what are the coordinates of a point that's common to both equations? how do you know?​

Answers

Answer:

14

Step-by-step explanation:

Answer:

(-4, 1)

Step-by-step explanation:

Solve it as a system of equations:

[tex]3x-2y=-14\\3x+y=-11[/tex]

subtract the two equations

[tex]-3y = -3[/tex]

divide both sides by -3

[tex]y=1[/tex]

Plug this into the equation 3x + y = -11 to solve for x

[tex]3x + 1 = -11\\[/tex]

subtract 1 from both sides

[tex]3x = -12[/tex]

divide both sides by 3

[tex]x = -4[/tex]

So the answer is (-4, 1)

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

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.

In triangle ABC, the measure of C is 90°,
AC=24, and BC=10. What is the value of sin
A?

Answers

Answer:

Sin A = 0.38462

Step-by-step explanation:

From the trigonometric function,

Sin A = [tex]\frac{Opposite}{Hypotenuse}[/tex]  ................... 1

So that, applying the Pythagoras theorem to determine the value of hypotenuse,

[tex]/Hyp/^{2}[/tex] = [tex]/Opp/^{2}[/tex] + [tex]/Adj/^{2}[/tex]

            = [tex]24^{2}[/tex] + [tex]10^{2}[/tex]

            = 576 + 100

[tex]/Hyp/^{2}[/tex] = 676

Hyp = [tex]\sqrt{676}[/tex]

       = 26

The hypotenuse of the triangle is 26.

Thus, from equation 1;

Sin A = [tex]\frac{10}{26}[/tex]

Sin A = 0.38462

So let's put this question into one equation.

x - 16 = 4 if x = 20

Well, this is a true statement. If we were to replace x with 20. We would see that the equation makes sense.

20 - 16 = 4

20 minus 16 does indeed equal 4.
