Answer:
x^2+4x+4
Step-by-step explanation:
f(x)=x^2-2x, g(x) =6x+4
(f+g)(x)=f(x)+g(x)
(f+g)(x)=x^2+4x+4
dilation by a scale factor of 2, then a reflection over the x-axis
dilation by a scale factor of 1/2, then a rotation of 180° about the origin
dilation by a scale factor of 1/2. then a reflection over the x-axis
Answer:
C : dilation by a scale factor of 1/2, then a rotation of 180° about the origin
Step-by-step explanation:
Which type of function will most closely match the data?
A) decreasing linear function
B) increasing linear function
C) exponential decay function
D) exponential growth function
Answer:
D) Exponential Growth Function
Step-by-step explanation:
This is because in a linear equation, there is a constant 'slope' of how something increases like a specific amount but in this equation, the growth is by a specific percentage which allows for a difference in the amount each year. For example, a linear function would be if it increased by four dollars every year, so 2, 4, 6, 8,etc. But a exponential function would be like if it increased by for percent each year, so 2, 2.16, 2.25, 2.34, etc.
Answer:
D) exponential growth function
Step-by-step explanation:
Answer:
1/4
Step-by-step explanation:
the numerator is 12 because there are 12 possible outcomes. The numerator is 3 because there are 3 numbers in this set that are greater than 9. You get 3/12 which then simplifies to 1/4
Answer:
(-.05 + .09 - .04 - .08 + x)/5 = -.01
(-.08 + x)/5 = -.01
-.08 + x = -.05
x = .03
The change in the barometric pressure on Friday is .03.
67, 57, 52, 51, 64, 58, 67, 58, 55, 59
Answer:
Step-by-step explanation:
First, we'll arrange the number sequence from lowest to highest - 0,50,50,51,52,55,57,57,58,58,58,58,59,60,62,63,64,66,67,67.
Second, we'll find the median Q2 - (58+58) / 2 = 58
Third, we'll take the middle numbers before the median as our lower quartile Q1 - (52+55) / 2 = 53.5
Fourth, we'll take the middle numbers after the median as our upper quartile Q3 - (62+63) / 2 = 62.5
