Bro i need this <br><br> (x − 5)^2 = x^2 − 25

forsale [732]

Answer:

x=5

Step-by-step explanation:

x^2+25-10x = x^2-25

-x^2 -x^2

25-10x = -25

-25 -25

-10x = -50

x=5

lets check

(5-5)^2 = 5^2-25

0^2 = 25-25

0 = 0

Janelle has 5 hours to spend training for an upcoming race. She completes her training by running full speed the distance of the

VikaD [51]

Answer:

The distance cover by him walking back is 11.25 miles

Step-by-step explanation:

Given as :

Time for Janelle to spend on training = 5 hours

The running speed of Janelle = 9 mph

The walking back with 3 mph

Let The distance for running and walking is same i.e D miles

SO, Time = $\frac{Distance}{Speed}$

∴ 5 = $\frac{D}{9}$ + $\frac{D}{3}$

Or, 5 × 9 = D + 3 D

Or, 45 = 4 D

∴ D = $\frac{45}{4}$ = 11.25 miles

Hence The distance cover by him walking back is 11.25 miles Answer

The equation of a parabola is 1/32 (y−2)2=x−1 .

Andru [333]

The given equation of parabola is

$\frac{1}{32} (y-2)^2 = x-1$

Which can also be written as

$x = \frac{1}{32} (y-2)^2 +1$

Here vertex (h,k) is (1,2)

And value of a is

$a = \frac{1}{32}$

Formula of focus is

$(h+ \frac{1}{4a} , k)$

Substituting the values of h,k and a, we will get

$(1+ \frac{1}{4*(1/32) } , 2} = (1+ 8,2) = (9,2)$

Therefore the correct option is the last option .
