An angle is bisected, forming two new angles. If the original angle had a measure of 14 degrees, what is the measure of each new angle?
Hello I think the answer would be 7
An angle bisector, bisects an angle into two equal small angles
14 divided by 2 is 7
Hope this helps :)
The measure of each new angle will be 7°.
Since we are given the information that the original angle had a measure of 14 degrees, then when the angle is bisected, forming two new angles, we have to divide the original angle by 2. This will be:
= 14°/2
= 7°
Therefore, the measure of each new angle will be 7°.

The function f is defined by f(x) = 2x²-1.
Find f (2x).
Answer: [tex]f(2x)=8x^2-1[/tex]
Step-by-step explanation:
All that is required here is to substitute x = 2x into the right side in the same way that is done for a numeric value.
[tex]f(2x) = 2(2x)^2-1\\f(2x) = 2(4)x^2-1\\f(2x) = 8x^2-1\\[/tex]
(a) Find a simplified form of the difference quotient and (b) complete the following table.
f(x) = - 4x + 7
Answer:
a) -4
b)
x h [f(x+h) - f(x)] / h
3 2 -4
3 1 -4
3 0.1 -4
3 0.01 -4
Step-by-step explanation:
a) The difference quotient is:
[f(x+h) - f(x)] / h
Our function is -4x + 7, then:
f(x+h) = -4(x+h) + 7 = -4x -4h + 7
f(x) = -4x + 7
f(x+h) - f(x) = -4x -4h + 7 - (-4x + 7 )= -4x -4h + 7 +4x - 7 = -4h
Finally:
[f(x+h) - f(x)] / h = -4h/h = -4
b)
First point in the table:
x = 3
h = 2
f(x+h) = -4(3+2) + 7 = -13
f(x) = -4(3) + 7 = -5
f(x+h) - f(x) = -13 -(-5) = -8
[f(x+h) - f(x)] / h = -8 / 2 = -4
Second point in the table:
x = 3
h = 1
f(x+h) = -4(3+1) + 7 = -9
f(x) = -4(3) + 7 = -5
f(x+h) - f(x) = -9 -(-5) = -4
[f(x+h) - f(x)] / h = -4 / 1 = -4
Third point in the table:
x = 3
h = 0.1
f(x+h) = -4(3+0.1) + 7 = -5.4
f(x) = -4(3) + 7 = -5
f(x+h) - f(x) = -5.4 -(-5) = -0.4
[f(x+h) - f(x)] / h = -0.4 / 0.1 = -4
Fourth point in the table:
x = 3
h = 0.01
f(x+h) = -4(3+0.01) + 7 = -5.04
f(x) = -4(3) + 7 = -5
f(x+h) - f(x) = -5.04 -(-5) = -0.04
[f(x+h) - f(x)] / h = -0.04 / 0.01 = -4

necessary, round your answer to 2 decimal places.

Abigail has $30.00 to buy groceries.she needs to buy some apples,some bananas, and 3 pounds of potatoes.Fuji apples are $1.79 a pound ,bananas are$0.36 each, and potatoes are 2.99 for a 3 lb bag. If a represents the number of pounds of apples Abigail buys b represents the number of bananas she buys,which expression represents the amount of change she receives after her purchases?
Answer:
An expression represents the amount of change she receives after her purchases is y=-1.79a-0.36b+27.01
Step-by-step explanation:
Let a represents the number of pounds of apples
Let b represents the number of bananas
Cost of 1 pound apple = $1.79
So, Cost of a pounds apples = 1.79 a
Cost of 1 banana = $0.36
Cost of b bananas = 0.36b
Cost of 3 lb bag of potato i.e. 3 pounds of potato = $2.99
So, Total cost = 1.79a+0.36b+2.99
Abigail has $30.00 to buy groceries
Let y be the change received by her
So, Change received by her:
y = 30-( 1.79a+0.36b+2.99)
y= 30-1.79a-0.36b-2.99
y=-1.79a-0.36b+27.01
Hence expression represents the amount of change she receives after her purchases is y=-1.79a-0.36b+27.01
