Parabolas in geometry. i need help please

Mathematics
1 answer:
natali 33 [55]3 years ago
7 0

Answer:

OPtion B

Step by step explanation:

Lets plug in a random value for x.

Lets say 5 is x

-8(-5-5)=(y+1)^2

5-5 = 0

-8(0) = 0

0 = (y+1)^2

Square root of both sides

0 = y+1

subtract one from both sides

-1 = y

that means the x is 5 and the y is -1. Option B illustrates exactly that!

Which expression is equivalent to -1/4 x + 1/2?
Anna71 [15]
The expression is given by:

-\frac{1}{4}x+ \frac{1}{2}

So we need to find an equivalent equation for this problem. Then, we will apply some mathematical rules:

Extracting the common factor 1/4, then:

\frac{1}{4}(-x+2})

Or extracting the common factor -1/4, then:

-\frac{1}{4}(x-2})

So, comparing these solutions with the answers about, there is no any answer that matches.

Find the value of y round your answer to the nearest tenth cos y y=8/13
Iteru [2.4K]

8/13 = 0.6153

y = cos-1(0.6153)

y = 52.0

I'm not totally sure if this is what you mean or if this is.

y = cos(8/13) = 0.9999 which to the nearest tenth is 1.0
