Find the gradient of the line segment between the points (7,2) and (10,-5).
Give your answer in its simplest form.
Answers
Answer:
-7/3
Step-by-step explanation:
Give your answer in its simplest form.
Gradient is also known as slope and it is expressed as;
Slope = y2-y1/x2-x1
Given the coordinate point (7,2) and (10,-5).
Slope = -5-2/10-7
Slope = -7/3
Hence the gradient of the line segment between the points is -7/3

For exponential functions of the form f(x)=a^x, which of the following expressions is equal to [f(b)]^c?
Answers
The expression that is equal to exponential function [tex][f(b)]^c[/tex] is [tex]a^{bc}[/tex]
How to determine the equivalent expression?The equation of the exponential function is given as:
[tex]f(x) = a^x[/tex]
Substitute b for x
[tex]f(b) = a^b[/tex]
Take the exponent of both sides to the power of c
[tex][f(b)]^c = (a^b)^c[/tex]
Apply the law of indices
[tex][f(b)]^c = a^{bc}[/tex]
Hence, the expression that is equal to exponential function [tex][f(b)]^c[/tex] is [tex]a^{bc}[/tex]

b. 55
Step-by-step explanation:
x+90+y = 180 (Being angles of a traingle)
35+ 90+y = 180
125 + y = 180
y = 180-125
Therefore , y=55
Suppose that for a particular piece of machinery, the frequency distribution of monthly breakdowns is as follows: Number of Breakdowns Prob. 0 .50 1 .25 2 .10 3 .10 4 .05 The cost of a breakdown is $2,000, and the cost of a preventive maintenance program is $2,000 per month. If the preventive maintenance program is adopted, the probability of a machine breakdown is negligible. How much better off per month would the firm be if it adopted preventive maintenance
Answers
Answer:
$100 worse off
Step-by-step explanation:
Number of Breakdowns : 0, 1, 2, 3, 4
Prob.: 0.50, 0.25, 0.10, 0.10, 0.05
Cost of a breakdown = $2,000
cost of a preventive maintenance program is $2,000 per month
Expected probability of breakdown:
E(x) = Σ(X * p(x)) = (0*0.5) + (1*0.25) + (2*0.10) + (3*0.10) + (4*0.05) = 0.95
E(x) * cost of breakdown = (0.95 * 2000) = $1900
Hence, difference between breakdown and preventive maintenance
1900 - 2000 = - $100
$100 worse off

Find the value of x that will make L parallel to m
Answers
Answer:
x = 7
Step-by-step explanation:
If L is parallel to M, therefore:
7x - 7 = 4x + 14 (alternate interior angles are congruent)
7x - 7 - 4x = 4x + 14 - 4x (subtraction property of equality)
3x - 7 = 14
3x - 7 + 7 = 14 + 7 (addition property of equality)
3x = 21
Divide both sides by 3
x = 7

Translate the following phrase into an algebraic expression. Do not simplify. Use the variable name x or y to describe the unknown 4 divided by the sum of 4 and a number
Answers
Answer:
the algebraic expression for the phrase 4 divided by the sum of 4 and a number is [tex]\mathbf{\frac{4}{4+x}}[/tex]
Step-by-step explanation:
Translate the following phrase into an algebraic expression.
We will use x to describe the unknown.
The phrase is: 4 divided by the sum of 4 and a number
The sum of 4 and a number can be written as: 4+x
4 divided by the sum of 4 and a number can be written into algebraic expression as: [tex]\frac{4}{4+x}[/tex]
So, the algebraic expression for the phrase 4 divided by the sum of 4 and a number is [tex]\mathbf{\frac{4}{4+x}}[/tex]
