Hello there!
Since we're looking for an equation to have a solution of x = -5, let's solve them from answer choice "A.)" to answer choice "D.)"
x + 10 = -5
x = -15
A.) is not correct.
Let's try B.)
-x^2 + 50 = 25
x^2 = -25
x = -5
Answer choice B.) is correct.
Let's continue looking for answer choices, just in case.
Let's look at answer choice C.)
2x = 10
x = 5
This answer is not correct.
Let's look at answer choice D.)
x < 0
This means x is less than 0, or a negative number.
This answer is not specifically correct.
Let's look at answer choice E.)
2x < 10
x < 5
This is less than 5, but does not specifically answer our chances.
Your answer is B.)
I hope this helps!
Answer:
Part 1 - A
Answer: 301.592895 m^3
Step-by-step explanation:
The formula for the volume of a cone is calculated the formula:
<u>V = πr^2h/3 </u>
In the question, we are given the value of the radius and height in meters through which we can calculate the volume.
r = 6
h = 8
and we know the value of π to be 22/7, or 3.14285714286.
By substituting these values in the formula, we can solve for volume of the cone:
V = π (6)^2 8 / 3
Volume = 301.592895 m^3
Hope this helps!
Answer:
542.50
Step-by-step explanation:
Given:
Least square regression equation :
y = 102.50 + 0.65x + residual
y = predicted fare
x = distance in miles
Intercept = 102.50
Slope = 0.65
Distance in miles, x = 500 miles
y = 102.50 + 0.65(500) + 115
y = 102.50 + 325 + 115
y = 427.5 + 115
y = 542.50

Answer:
Step-by-step explanation:
Given functions are:
We have to find:
(s.t)(x) => this means we have to multiply the two functions to get the result.
So,
Also we have to find
(s-t)(x) => we have to subtract function t from function s
Also we have to find,
(s+t)(-3) => first we have to find sum of both functions and then put -3 in place of x
Putting x = -3
Hence,
