Answer:
(3.5, 17)
Step-by-step explanation:
It would be nice to see the whole graph, so we can see where the functions cross.
Without that information, we can still eliminate unreasonable choices.
A) the quadratic at y=3.5 is well above the exponential
B) the most likely choice (3.5, 17)
C) at x=-8, the quadratic is above the exponential
D) neither graph goes anywhere near y = -8
If the quotient is positive, we know that the two integers are either both positive or both negative.
If the quotient is negative, we know that one integer is positive and the other is negative.
If the quotient is zero, then we are dividing 0 by some non-zero integer.
Answer: Relative error = 50%
Step-by-step explanation:
Relative error Re = Absolute error/True value × 100%
True value = 2 scoops
Measured(used) value = 3 scoops
Absolute error Ae = measured(used) value - True value
= 3 scoops - 2 scoops
Ae = 1 scoop
Re = 1/2 × 100%
Re = 50%
Answer:
8
Step-by-step explanation:
77+50=127
180-127=53
7x-3=53
7x=53+3
7x=56
x=56/7
x=8

Modeling as a right triangleThis situation can be modeled by the following right triangle. The hypotenuse is 100 meters and the height is 42 meters. <span>We are asked to find the angle of elevation, which is the angle on the left.
</span>Determining the appropriate trigonometric ratio
We are given the side opposite to the missing angle and the hypotenuse <span>The appropriate trigonometric ratio is therefore the SINE.
</span>
<span>
Forming an equation and solving</span>
Denoting the missing angle by θ, we obtain the equation

<span>
</span>Solving the equation, we get

Evaluating this result in the calculator and rounding to the nearest tenth, we get θ =

degrees.
