If a/b=b/c,then what is b²?​

Answers

Answer 1

Given:

The equation is

[tex]\dfrac{a}{b}=\dfrac{b}{c}[/tex]

To find:

The value of [tex]b^2[/tex].

Solution:

We have,

[tex]\dfrac{a}{b}=\dfrac{b}{c}[/tex]

On cross multiplication, we get

[tex]a\times c=b\times b[/tex]

[tex]ac=b^2[/tex]

[tex]b^2=ac[/tex]

Therefore, the value of [tex]b^2[/tex] is [tex]ac[/tex].

Evaluate the function.
f(x) = -2x2 + 8x – 10
Find f(-4)

Answers

Answer:

f(-4)=-2(-4)²+8(-4)-10=-2×16-32-10=-74

Step-by-step explanation:

Given

f(x) = - 2x² + 8x - 10

f(-4) = - 2 * (-4)² + 8 * ( -4 ) - 10

= - 32 - 32 - 10

= - 74

Answers

Answer:

A

Step-by-step explanation:

Assuming the dilatation is centred at the origin, then each coordinate of the original point is multiplied by the scale factor 2, that is

D(- 4, 6 ) → D'(2(- 4), 2(6) ) → D'(- 8, 12 )

E(4, 2 ) → E'(2(4), 2(2) ) → E'(8, 4 )

F(- 2, - 2 ) → F'(2(- 2), 2(- 2) ) → F'(- 4, - 4 )

Thus the image coordinates are

D'(- 8, 12 ), E'(8, 4 ), F'(- 4, - 4 ) → A

1.4 pounds of almonds, 0.8 pound of cashews, and 2.6 pounds of peanuts. How much does Mila spend in all

Answers

Answer:

WHAT WOULD THIS BEEEEEEE!!

Answers

Answer:

c) 30

Step-by-step explanation:

since the lines are parallel, 75° = 2x + 15°

this is because when two parallels lines are intersected by the same line, all respective angles are equal. Also, opposite angles on a line are equal too.

So now that u have 75 = 2x + 15, just solve for x by simplifying:

75 = 2x + 15

60 = 2x

30 = x

so the answer is c) 30
