Answer:
Step-by-step explanation:
Find the rows in the table where f(x) shows the same value as g(x). Those rows are ...
x = -1, f(x) = 1, g(x) = 1
x = 1, f(x) = -7, g(x) = -7
The values of x are what is of interest. They are -1 and 1.
Answer:
135
Step-by-step explanation:
(7+3)^2 + (8-1) * 5
Parentheses first
(10)^2 + (7) * 5
Exponents next
100 + 7*5
Multiply
100 + 35
Add
135
12 -2x < 16
First, subtract 12 from both sides.
-2x < 16 - 12
-2x < 4
Divide both sides by -2
x > -2 (you switch the < sign with > when divided by a negative).
Because it is not greater than/less than or equal to, it is an open circle at -2. Any number that is greater than -2 means it's shaded to the right, the answer's B.
Answer:
602.9 cm²
Step-by-step explanation:
==>Given:
A hemisphere with radius of 8cm
π = 3.14
==>Required:
Total surface area of hemisphere
==>Solution:
The total surface area of the hemisphere (TSA) = Curved surface area of hemisphere (CSA)+ base area (BA)
If surface area of a sphere is given as 4πr², therefore, the area of a hemisphere would be ½ of 4πr² = 2πr²
CSA = 2πr²
Base area (BA) = area of circle = πr²
Thus, TSA = 2πr2 + πr2 = 3πr2
TSA of hemisphere = 3 × 3.14 × 8²
TSA = 3 × 3.14 × 64
TSA = 602.88
TSA of hemisphere = 602.9 cm² (approximated to 1 decimal place)
Answer:
1. D
2. E
3. B
4. C
5. A
5. F
Step-by-step explanation:
The <u>median</u> can be found at the line inside of the box, the <u>heaviest</u> weight would be found at the right end of the line, and the <u>smallest </u>weight would be found at the left, the <u>interquartile range</u> is the difference of one end of the box to the other, and the<u> range</u> is the difference of the largest number of the entire diagram, from the smallest number.
Hope this helps you!
