If y=x^2 and x=(-8) then y =...

Mathematics
1 answer:
lutik1710 [3]3 years ago

Answer:

-64

Step-by-step explanation:

If

y=x^2

and the x represents -8

Your answer will be -64

By saying that x=(-8)   all you have to do is plug in the negative 8 to the original equation of y=x^2. This would make it   y=(-8)^2

When you plug in negative 8 to the second power into the calculator your answer will be -64

I hope this helps king!

Well, start from 100% and work backwards.

It takes 5600 years to get to 50%
Another 5600 years to get to 25%
And a bit under another 5600 to get to 15% (another 5600 years would get it down to 12.5%)

Add the first two 550s to get 1120, and add about 5,000 and see which answer is closest.
In this case, D is closest at 15!w29

There are more exact ways of solving, but for a multiple choice this is faster and efficient nonetheless

Emma jogs 2 miles along the beach in 1 3 of an hour. If she travels at a constant rate, how far will she jog in an hour? 1. Use
Aliun [14]

Answer:

Step-by-step explanation:

Emma jogs 2 miles along the beach in 1/3 of an hour. At a constant rate, the distance that she jogs on 1 hour would be

Let x represent the number of mikes that she would jog in 1 hour.

If 2 miles = 1/3 of an hour, then

x = 1 hour

Cross multiplying, it becomes

x × 1/3 = 2 × 1

x/3 = 2

x = 3 × 2 = 6 miles

The equivalent rate with a denominator of 1 is 6/1 miles

PLSS help me with this question?
Xelga [282]

Answer:

Part a) By alternate interior angles

Part b) By vertical angles

Part c)  By AAA (Angle-Angle-Angle) Similarity Theorem

Part d) Triangles ABC and CDE are similar

Part e) b=\frac{2DE}{3}  or  b=\frac{15}{AC}

Step-by-step explanation:  

Part a)

we know that

If AB is parallel to DE

then

m<1=m<4 ------> by alternate interior angles

Part b)

we know that

m<5=m<6 -------> by vertical angles

Part c) we know that

The two triangles are similar by AAA (Angle-Angle-Angle) Similarity Theorem ------> The three corresponding angles are equal

so

m<1=m<4

m<5=m<6

m<3=m<2

Part d) we know that

If two figures are similar, then the ratio of its corresponding sides is equal and its corresponding angles are congruent

therefore

Triangles ABC and CDE are similar

Part e) Find the length side of b

Remember that

If two figures are similar, then the ratio of its corresponding sides is equal

so

\frac{AB}{DE}=\frac{BC}{DC}=\frac{AC}{CE}

substitute the values

\frac{3}{DE}=\frac{2}{b}=\frac{AC}{7.5}  

b=\frac{2DE}{3}

or

b=\frac{2*7.5}{AC}=\frac{15}{AC}
