Answer:
$405.60
Step-by-step explanation:
40x13=520
520x.22= 114.4
520-114.4=405.60
As with the other 2, the scale is 2 and since there is 2 points between it, it is 4 higher than 13 which means the answer is 17
The numeric value of the expression d² + 3a + 6 + a when a = 2 and d = 5 is of 39.
<h3>How to find the numeric value of an expression?</h3>
The numeric value of a function is found replacing each instance of a variable by the value of the input for which we want to find the numeric value.
For this problem, the expression is given by:
d² + 3a + 6 + a
We want to find the numeric value when a = 2 and d = 5, hence:
5² + 3(2) + 6 + 2 = 25 + 6 + 6 + 2 = 39.

b=9/4
y=(-1/4)x+(9/4)
Answer:
C and D are unchanged, but E increases.
Step-by-step explanation:
Given equation of circle
x^2+y^2+Cx+Dy+E=0
But we know that general equation of circle is with center at (h,k)
x^2 + y^2 -2hx -2ky + (h^2 + k^2 – r^2) = 0
Comparing both equations we get,
C = -2hx
D = -2ky
As in the given question we are not changing the coordinates of center so C and D will remain unchanged.
It also gives us
E = (h^2 + k^2 – r^2)
Decreasing r means that a lesser quantity will be subtracted from h^2 + k^2 which will increase the value of E.
