What you should do in this case is to see the terms that are repeated in the expression.
We have then that the terms are a and b.
Making a common factor we have:
a * b (a * b -7) +10
Answer:
The equivalent expression is:
a * b (a * b -7) +10
Regardless of how the sphere<span> is cut, it will form a circle</span>
Answer:
y = -1/4x - 6
Step-by-step explanation:
Write the equation in the form y = mx + b. First find the slope (m), then find the y-intercept (b). Leave the y and the x as they are.
I gave the slope-intercept form. :) Hope it helps!
Answer:
6.875° C
the mean of a set of data is calculated using
mean =
For the first 7 days the mean is 8 and the count = 7
8 = ( cross- multiply )
sum = 8 × 7 = 56
Add on the temperature on the 8 th day to the sum and divide by 8 for mean
sum = 56 - 1 = 55
mean = = 6.875° C
2nd question
Height of marble from the ground
An independent variable is the variable in an experiment that you change to see if it has an effect on the dependent variable. In this case, Jack wanted to see whether the position of the marble on the ramp (which would be the height) has an effect on the kinetic and potential energy of the marble, then the height would be the independent because it is what is being changed.
The dependent would be the kinetic and potential energy and the constant would be the type of marble.
