C: If you are interested in upward motion, Friction is not going to be the answer. What will the rocket rub against to make it go up?

D: Centripetal Force has to do with circular motion, The rocket generally is not thought of as going in a circle. Not D.

Answer: B. A chemical reaction can be directed so the energy will force an upward motion.

The original value of the piece of equipment is 700000

The resale value is given as:

V=700,000e^(-0.02t)

The original value is when t = 0.

So, we have:

V=700,000e^(-0.02 *0)

Evaluate the product

V=700,000e^0

This gives

V=700,000 * 1

Evaluate

V=700000

Hence, the original value of the piece of equipment is 700000

Answer:  A rose bush, r, cost $8; one pot of ivy, i, cost $6;

Step-by-step explanation:

[tex]\left \{ {{5r + 3i =58} \atop {5r+10i=100}} \right.[/tex]

We combine them by minus, we get:

    5r + 3i = 58

-    5r + 10i = 100

           - 7i = - 42

               i = 6

We plug in i = 6 to the first equation, we get:

     5r + 3(6) = 58

        5r + 18 = 58

                5r = 40

                  r = 8

The cost of one rose bush is $8 and the cost of one pot of ivy is $6.

Here are the equations to represent the scenario:

Micaela: 5r + 3i = 58

Chelsea: 5r + 10i = 100

Let's solve the system of equations to find the cost of one rose bush (r) and one pot of ivy (i).

Subtracting the first equation from the second equation, we get:

7i = 42

Dividing both sides by 7 we get:

i = 6

The rose bushes will be:

5r + 3i = 58

5r + 18 = 58

5r = 58 - 18

5r = 40.

r = 8

This means that the cost of one rose bush is $8 and the cost of one pot of ivy is $6.

the transformation from f(x) to g(x) is (c) the graph of g(x) is horizontal compression of the graph f(x) by a factor of 1/3 and a reflection across the x-axis.

The functions are given as:

f(x) =x^3

g(x) = -(3x)^3

The minus sign in g(x) = -(3x)^3 implies that the function f(x) is reflected across the x-axis

The 3 in g(x) = -(3x)^3 implies that the function f(x) is stretched horizontally by 1/3

Answer:

  2448 ft²

Step-by-step explanation:

The surface area of the triangular prism is the sum of the areas of the triangular bases and the lateral area of the rectangular faces.

The two right triangle bases together form a rectangle that is 24 ft wide and 18 ft tall. The total base area is ...

  A = (24 ft)(18 ft) = 432 ft²

The rectangular faces of the prism are each 28 ft wide and have a total width of 18 +24 +30 = 72 ft. Their total area is ...

  LA = (28 ft)(72 ft) = 2016 ft²

The sum of the base area and lateral area is ...

  total area = (432 ft²) +(2016 ft²) = 2448 ft²

The surface area of the triangular prism is 2448 ft².

__

Additional comment

The area formula for the triangular base is ...

  A = 1/2bh . . . . . . area of one triangle with base b and height h

Then the area of the two congruent triangular bases is ...

  A = 2(1/2bh) = bh

This is the formula we used above. It skips the work of dividing by 2, then multiplying by 2 again.

The exact values of the remaining trigonometric functions are sin(x) = -7/25 and tan(x)= -7/24

The function is given as:

cos(x) = 24/25, tan(x) < 0

The sine function is calculated using:

sin^2(x) + cos^2(x) = 1

So, we have:

sin^2(x) + (24/25)^2 = 1

Collect like terms

sin^2(x) = -(24/25)^2 + 1

Evaluate the squares

sin^2(x) = -576/625 + 1

Take the LCM

sin^2(x) = (625-576)/625

Evaluate

sin^2(x) = 49/625

Take the square roots

sin(x) = -7/25 --- sin(x) is negative because tan(x) < 0

The tangent function is calculated using:

tan(x) = sin(x)/cos(x)

This gives

tan(x) = (-7/25) / (24/25)

Evaluate

tan(x)= -7/24

Hence, the exact values of the remaining trigonometric functions are sin(x) = -7/25 and tan(x)= -7/24
