Answer:
x^2 +2x -5
Step-by-step explanation:
f(x) = 2x+3
g(x) = x^2 -8
f(x)+g(x) = 2x+3+ x^2 -8
Combine like terms
= x^2 +2x -5
Answer:

<u>Image 1 Use:</u>
tan(angle) = opposite/adjacent
<u>Image 2 Use:</u>
cos(angle) = adjacent/hypotenuse
<u>Image 3 Use:</u>
a² + b² = c²
If you're given an angle and 1 side then you can use sin(), cos(), or tan() to solve for the other missing side.
If you're given two sides then you can use the pathagorean theorem, a² + b² = c², to solve for your missing side.
Answer:
15. a 7.9 miles
b. NO .
Step-by-step explanation:
From the table, on
Monday = 3 2/5
Wednesday = 4 1/2
Write the distance in improper fractions as;
Monday = 17/5
Wednesday = 9/2
Find the sum as
where the L.C.M is 10
Answer is 7.9 miles
b.
Distance covered on Thursday and Saturday will be
2 2/6 + 3 3/4
14/6 + 15/4 ------the L.C.M is 12
(28+45)/12
73/12
The distance 73/12 miles for Thursday + Saturday is less than that of Monday + Wednesday 79/10 miles. The answer is NO.
Answer:
Population: Adults in the United States
Sample: 2276 adults in the United States
33% is a statistic.
Step-by-step explanation:
The population consists of adults in the United States because that is the wider range, and the sample is 2276 of those adults.
The value 33% is an statistic due to the definitions of both words. A statistic is defined as a fact or piece of data obtained from a study of a large quantity of numerical data. While a parameter is a numerical or other measurable factor forming one of a set that defines a system or sets the conditions of its operation.
