9. Evaluate the ceiling function for the given value.
A. f(x) = ⌈x⌉; x = −7.4

B. g(x) = ceiling (x, 0.50);
x = 21.27

Answers

Given:

A. f(x) = ⌈x⌉; x = −7.4

B. g(x) = ceiling (x, 0.50); x = 21.27

To find:

The values of ceiling function for the given value.

Solution:

We have,

f(x) = ⌈x⌉; x = −7.4

Here, f(x) is a ceiling function, so we need to find the nearest next integer value because if m < x ≤ n, then ⌈x⌉ = n, where m and n are integers.

Now,

f(-7.4) = ⌈-7.4⌉

f(-7.4) = -7

Therefore, the value of f(x) is -7 at x=-7.4.

g(x) = ceiling (x, 0.50); x = 21.27

Here, g(x) is a ceiling function with 0.50, so we need to find the nearest next multiple of 0.50 because if m < x ≤ n, then ⌈x⌉ = n, where, m and n are multiples of 0.50.

Now,

g(21.27) = ceiling (21.27, 0.50)

g(21.27) = 21.50

Therefore, the value of g(x) is 21.50 at x=21.27.

Write the power of 10 to multiply the divisor by to make it a whole number. Then, write the equivalent problem and find the quotient.

16.65 divided by 0.37
i need halp wit this and also i brainly keeps deleting meh questions

Answers

Answer:

Step-by-step explanation:

The equivalent problem is 16.65×10²/0.37×10² and the quotient is 45.

What is a quotient?

In arithmetic, a quotient is a quantity produced by the division of two numbers. The quotient has widespread use throughout mathematics, and is commonly referred to as the integer part of a division, or as a fraction or a ratio.

Given that, 16.65 divided by 0.37.

Now, multiply both numerator and denominator by 10², we get

16.65×10²/0.37×10²

= 1665/37

= 45

Therefore, the quotient is 45.

Find the slope and y-intercept of the following graph.

Answers

The slope is 2/3 (4/6) and the y-intercept is 3

Answer:

y-intercept: 3

slope: 2/3

Step-by-step explanation:

The y-intercept is the point that crosses the y-axis. In this case the y-intercept is 3.

When figuring out the slope, there are some methods. I am going to be using the rise over run method. Start at one point and go up and over untill it hits another point on a graph. Start at (-3,1). Go up 4. Go over 6. You will land on the point (3,5). Your answer will be 4/6. Simplify 4/6 and then you will get 2/3.
