Simplifying this would be: 8x + 4
Answer:
when x= -4, y= 2
when x= 6, y =7
Step-by-step explanation:
We have the x values, so we can plug them in and solve. for the first problem, it becomes y =1/4 (-4)^2 -2
first we do the exponent
y= 1/4 (16) - 2
Then the multiplication
y= 4-2
then subtraction
y=2
For the second problem, it becomes y= 1/4 (6)^2 -2 We follow the same steps
y = 1/4 (36) - 2
y= 9-2
y= 7
Answer:
The angle is .
Step-by-step explanation:
The building is 35 feet tall, and the rope is 400 feet long.Applying the trigonometric function, we have;
Sin θ =
The height of the building represents the opposite side, while the length of the rope represents the hypotenuse. Thus;
Sin θ =
Sin θ = 0.0875
θ = 0.0875
=
The angle made by the rope with respect to the ground is approximately .
Answer:
Without tax the shoes would cost £55.9.
Step-by-step explanation:
To get this you take the £86 and multiply it by 0.65 because with the 35% sale you are paying for 65% of the item. You get this number by subtracting 35 from 100 and convert it into a decimal.
