The mistake she made was saying it was a $25 discount when in the equation it said adding 25, and discount is subtraction so that is the mistake.
the new equation is 9x-25=88
Answer:
The answer is 11.
Step-by-step explanation:
You just plug in the numbers for each one! Hope this helps! Brainly if so!
First, we imagine a right triangle. Second, we are given that the building is 62 feet tall. Since the height of building is vertical straight - that means the height is opposite side of triangle. It also casts a shadow 21 meters long. Shadow should be the adjacent side because it casts on the ground and not on the air.
If we imagine the right triangle + the problem in our head, we'd get the triangle that the opposite side is 62 feet tall and the adjacent side is 21 meters long.
Use the tangent ratio to find the angle of sun shining.

Substitute adjacent = 21 and opposite = 62 in the ratio.

For this part, you might need a calculator or trigonometric table because some values cannot be exactly found.
From the equation, we should get 71.288 which we round the answer to nearest hundreth and the answer would be 71.29
Answer
A: Looking at the last two rows of the table of f(x), the slope is simply (3-0)/(1-0) = 3, while the slope of g(x) is the coefficient of the variable x, which is 7.
B. y-int is the y value when x = 0. f(x) has a y-int of 0, which g(x) is 2. The latter has a greater y-int.
Answer:
28 feet
Step-by-step explanation:
20 + 10 = 30 - 2 = 28 feet
The dolphin is 20 feet below the surface, goes down another 10 feet, so 30 feet below the surface, and raises two feet, so 28 feet below the surface.
