Answer:
B
Step-by-step explanation:
2.5 + (-1.5) = 1.0
2.5 - 1.5 = 1.0
To determine the cost of the mail, we simply substitute the mass of the package to the given function. Mathematical functions are used to relate two variables, observing how changing one variable affects the other variable. For this case, the cost of a mail and the weight of the package are related by the function <span>y = 0.7x2 –2.5x + 3 where x represents the mass in units of pounds (lb) and y is the cost in units of dollars ($). We calculate cost as follows:
</span><span>y = 0.7x^2 –2.5x + 3
</span><span>y = 0.7(5)^2 –2.5(5)+ 3
y = 8 dollars
Therefore, the cost of mailing a 5 lb package would be 8 dollars.</span>
The approxiamte area of the segemnt would be 56.71 becuase if you use the radious of a a circle and then didvide by then it will give you 56.71
Slope intercept form is y=mx+b. So let's use the given equation and turn it into this form.
Move the -3x to the right side
Divide both sides by -5
This should be your answer, let me know if you need any clarifications, thanks!
Answer:
9.5%
Step-by-step explanation:
To find percentage, we need to find an equivalent number with denominator 100. Multiply both numerator & denominator by 100
38
/400
×
100/100
= (
38 × 100
/400
) ×
1
/100 = 9.5/100
Therefore, the answer is 9.5%
