Answers
Answer:
Step-by-step explanation:
y=mx+b
m=(y2-y1)/((x2-x1)
m=(12-7.5)/(120-30)
m=0.05
y=0.05x+b, using point (30,7.5)
7.5=0.05(30)+b
7.5=1.5+b

Determine whether the following statements are true and give an explanation or counterexample. If f is not one-to-one on the interval [a, b], then the are of the surface generated when the graph of f on [a, b] is revolved about the x-axis is not defined.
Answers
Answer:
Step-by-step explanation:
The missing equation is:
[tex]S = \int ^b_a 2 \pi f(y) \sqrt{1 + f' (y)^2 } \ dy[/tex]
Suppose f = nonnegative function whose first derivative is within (a,b) and it is continuous, Then the area of the surface generated is revolved about the x-axis:
The area of the surface revolution is:
[tex]S = \int ^b_a 2 \pi f(x) \sqrt{1 + f' (x)^2 } \ dx[/tex]
So; if [tex]x = g(y)[/tex] for [tex]y \ \varepsilon \ [c,d][/tex]
Then; substituting a with c and b with d; f(x) also with g(y) and dx with dy;
Then;
[tex]S = \int ^d_c 2 \pi g(y) \sqrt{1 + g' (y)^2 } \ dy[/tex]
SInce;
[tex]g(y) \ne f(y)[/tex]; Then the statement is false.
Provided that the semicircle [tex]y = \sqrt{1-x^2}[/tex] isn't on [tex][-1,1][/tex] interval.
Then, the solid generated by the revolution about the x-axis is a sphere.
However, the surface is well defined and the statement is false.

22
Step-by-step explanation:
Using the expression to determine the value of c
121 = (c/2)²
find c
121 = c²/4
c² = 121 * 4
c = √121*4
c = √484
c = 22

A restaurant has 23 tables. Some of the tables seat 4 persons and the rest seat two persons. In all, 76 persons can be seated at once. How many tables of each kind are there?
Answers
Answer:
15 tables with 4 seats and 8 tables with 2 seats.
Step-by-step explanation:
x = 4 seated tables
y = 2 seated tables
x + y = 23
4x + 2y = 76
Multiply first equation by -2 to cancel y's:
-2x - 2y = -46
4x + 2y = 76
2x = 30
x = 30 / 2
x = 15
And we said 23 tables so:
23 - 15 = 8
x = 15
y = 8
Sixteen is divided by the sum of the number q and 1. The result is four. What is the number.
Answers
Answer:
The number is 3.
Step-by-step explanation:
Ok, so here we're solving for a variable. The equation would be:
16 ÷ (q + 1) = 4
We can rewrite this as:
4(q + 1) = 16
First, you need to isolate q + 1. To do that, you to the inverse of the operation. IN this case, division is the inverse of multiplication. So:
4(q + 1) = 16
÷4 ÷4
q + 1 = 4
Alright, now we isolate q. The inverse of addition is subtraction, so we do this:
q + 1 = 4
- 1 - 1
q = 3
Now for our check:
16 ÷ (q + 1) = 4
16 ÷ (3 + 1) = 4
16 ÷ 4 = 4
4 = 4
q = 3

503 inches (rounded to the nearest whole number)
Step-by-step explanation:
First, we must calculate the wheel's circumference, or in other words, the distance around the wheel. We can do this by using the below equation:
[tex]C=\pi d[/tex] when [tex]d[/tex] is the diameter
Because we know that the wheel's diameter is 16 inches, we can plug it into the equation:
[tex]C=\pi (16)\\C=16\pi[/tex]
Now, because we know that the wheel makes 10 revolutions, we calculate the distance it travelled by multiplying the circumference by 10.
[tex]16\pi *10\\= 160\pi[/tex]
[tex]= 503[/tex] inches when rounded to a whole number
Therefore, the wheel travelled approximately 503 inches.
