=$11.50
^^hope it helps :) sorry if the answer is wrong

Answer 2

Answer:

Answer: 11.50

Step-by-step explanation:

6$ to get in+ rides=$

11(rides)*.50(price of rides)=5.50

5.50+6=$11.50

42 = -7 (z - 3)

z = ?

Answers

Answer:

The answer to your question is z = -3

Step-by-step explanation:

Expand 42 = -7(z - 3)

42 = -7z + 21

Simplify 7z = -42 + 21

7z = -21

Clear z z = $(-21)/(7)$

z = -3

42=-7z+21
42-21=-7z
21/-7=-7z/-7
-3=z

Multiplies to -0.72 and adds to 0.6

Answers

Multiplies to -0.72 = - 0.6 * (1.2).

Adds to 0.6 =

-0.6 + (1.2) = 1.2 - 0.6 = 0.6.

Hence the two numbers are -0.6 and 1.2.

Can anyone show me the steps and answer?

Answers

Answer:

(-∞, 3) ∪ (3, 4) ∪ (4, ∞)

Step-by-step explanation:

Steps:

1. Read and understand the question. Here, you're being asked for the domain of a rational function, one with a 2nd-degree polynomial in the denominator. The domain is the set of x-values for which the function is defined.

2. Understand that the function will be undefined when the denominator is zero, so to answer the question, you must find the values of x that make the denominator zero.

3. Use any of the methods you have been taught to determine the zeros of the denominator polynomial. For this one, it is convenient to factor it:

x² -7x +12 = (x -3)(x -4)

The values of x that make this zero are 3 and 4, so these values are excluded from the domain.

4. Write an expression in interval notation that includes all real numbers except 3 and 4. That is, you want to translate this to interval notation:

(-∞ < x < 3) ∪ (3 < x < 4) ∪ (4 < x < ∞)

Using what you know about interval notation, you write it as ...

(-∞, 3) ∪ (3, 4) ∪ (4, ∞)

Solve the differential equation using the method of undetermined coefficients a) 4y"- 4y'-3y= cos2x

Answers

First: the homogeneous solutions: the characteristic equation is4r^2 - 4r - 3 = 0which has roots r = 3/2, -1/2 hence the homogeneous solution isy = c1.exp(-x/2) + c2.exp(3x/2)

next you need the general form for the guess for yp and that isyp = A1cos(2x) + A2sin(2x)
Now substitute that into the equation and solve for A1, A2.

on monday a company stock close at a price of $30.80 per share on tuseday it increased by $1.20 per share on wenseday it fell by 6.25% on thursday it fell by another 4% and friday it increased by 2.5% what is the net change in the stock price from monday to friday

Answers

Tuesday:
30.80 + 1.20 = 32.00

Falling by 6.25% means it ends up being 93.75% of what it used to be (100% - 6.25% = 93.75%)

Wednesday:
32.00 * 0.9375 = 30

Thursday:
30 * 0.96 = 28.8

Friday:
28.8 * 1.025 = 29.52

Net change means you subtract to get the difference.

Net change = Final - initial
= 29.52 - 30.80
= -1.28

The stock fell $1.28

Hope this helps!
