Answer:

13x13x5

Step-by-step explanation:

We can write 845 as

845 = 13 x 13 x 5

because

845 = (13x13) x5 = 169 x5 = 845

so the expression is

13 x 13 x 5

3-5 = 4a - 7(1 - 5a)

Semmy [17]

Answer:

a = 5/39

Step-by-step explanation:

We assume you want to solve the equation for "a".

-2 = 4a -7 +35a . . . . simplify

5 = 39a . . . . . . . . . . add 7

5/39 = a . . . . . . . . . divide by the coefficient of a

If f(x)=4x-1 and g(x)=x^2+7 ,find G(f(x))

frutty [35]

Answer:

$g(f(x))=(4x-1)^2+7=16\,x^2-8x+8$

Step-by-step explanation:

Given:

$f(x)=4x-1\\and \\g(x)=x^2+7$

Then the composition of functions:

$g(f(x))=g(4x-1)=(4x-1)^2+7= (16\,x^2-8x+1)+7=16\,x^2-8x+8$

where we have written the final functional expression in its standard form.

6. Two points in the plane, ????(19,4) and ????(19,−6), represent the endpoints of the diameter of a circle.

dusya [7]

Answer:

Radius = 5

center is (19,-1)

$(x-19)^2(y+1)^2= 25$

Step-by-step explanation:

Two points in the plane, (19,4) and (19,−6), represent the endpoints of the diameter of a circle.

Distance between the points is calculated using formula

$d=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}$

$=\sqrt{\left(19-19\right)^2+\left(-6-4\right)^2}=10$

diameter = 10

radius = diameter divide by 2

Radius = 5

midpoint is the center of the circle

$\left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)$

$\left(\frac{19+19}{2},\:\frac{-6+4}{2}\right)$

(19,-1)

Equation of the circle

$(x-h)^2(y-k)^2= r^2$

h,k is the center and r is the radius

h=19 and k=-1 , r=5

$(x-19)^2(y+1)^2= 25$

the equation f=v+at represents the final velocity of an object f, with an initial velocity,v, and an acceleration rate a,over ti

vfiekz [6]

F=v+at
f-v=at
(f-v)/t =a
the first choice is correct :)
