I’ll assume the c is b. (1/2) x (5) x (2) x (2) is 10

Answer: 10

Concept:

Here, we need to understand the idea of evaluation.  

When encountering questions that gave you an expression with variables, then stated: "If x = a, y = b, z = c" (a, b, c are all constants), this means you should substitute the value given for each variable back to the expression.

Solve:

**Disclaimer** I assumed that the [1/2] in [<u>1/2</u>ac2] is a single term and [c2] in [1/2a<u>c2</u>] is b². If it was, then you may refer to my answer. If it was not, then you may tell me and I will redo it.

<u>Given information</u>

a = 5

b = 2

<u>Given expression</u>

(1/2) · a · b²

<u>Substitute values into the expression</u>

=(1/2) · (5) · (2)²

<u>Simplify exponents</u>

=(1/2) · (5) · (4)

<u>Simplify by multiplication</u>

=(2) · (5)

=10

Hope this helps!! :)

Please let me know if you have any questions

Select all points that are on the line through 0,5
Rus_ich [418]

Answer:

Options (1), (3), and (4)

Step-by-step explanation:

Since, slope of a line passing through two points (x_1,y_1) and (x_2,y_2) is given by,

m = \frac{y_2-y_1}{x_2-x_1}

Therefore, slope of a line passing through (0, 5) and (2, 8) will be,

m = \frac{8-5}{2-0} = 1.5

Equation of line passing through (x', y') and slope 'm' is,

y - y' = m(x - x')

Therefore, equation of a line passing through (0, 5) and slope = 1.5,

y - 5 = 1.5(x - 0)

y = 1.5x + 5

Since, all the points which lie on this line will satisfy this equation.

For (4, 11),

11 = 1.5(4) + 5

11 = 11

Point (4, 11) lies on this line.

Point (5, 10)

10 = 1.5(5) + 5

10 = 7.5 + 5

10 = 12.5

But 10 ≠ 12.5

Therefore, (5, 10) doesn't line on the line.

Point (6, 14)

14 = 1.5(6) + 5

14 = 14

True.

Therefore, (6, 14) lies on the line.

Point (30, 50)

50 = 1.5(30) + 5

50 = 50

True.

Therefore, (30, 50) lies on the line.

Point (40, 60)

60 = 1.5(40) + 5

60 = 65

But 60 ≠ 65

Therefore, (40, 60) doesn't lie on the line.

Options (1), (3) and (4) and the correct options.

The value 3.84 is 12% of what number?
xeze [42]
So percent means parts out of 100
so 12%=12/100=1.2/10=0.12/1=0.12

3.84 is 12% of what
'of' means multiply
'is' means = sign

therefor
3.84=0.12 times what
divide both sides by 0.12
32=what

th enumber is 32

Someone pls help me
Troyanec [42]

The slope greater than one would be the last image, because for every step in x, you get more than one y step.

The slope between 1 and 0 would be the second image

And the slope less than 0 would be the third image
