Answer:
a = 3
Step-by-step explanation:
Evaluating the given function at the point, we have ...
f(-1) = a(-1)^2 +1 = 4
a +1 = 4
a = 3
The value of 'a' is 3.
Answer:
Step-by-step explanation:
First view 2x-5y<15 as the equation 2x - 5y = 15. Find the x- and y-intercepts and plot them:
x-intercept: let y = 0 and find x: x = 15/2. Plot (0, 15/2).
y-intercept: Let x = 0 and find y: y = -3. Plot (0, -3).
Draw a dashed line through these two points. Shade the area BELOW this line.
If the exterior sides of adjacent angles are opposite rays, then the angles are supplementary.
Supplementary angles are two angles whose sum is 180 degrees.
Answer:
6.09 * 10 ^-3
Step-by-step explanation:
We want one non zero digit to the left of the decimal
Move the decimal 3 places to the right
6.09
The exponent is 3 and it is negative since we move to the right
6.09 * 10 ^-3
