Mamont248 [21]

Answer:

a = 16

b = \frac{3}{4}

Step-by-step explanation:

Length of the design 16 inches is represented by the point (0, 16) and length of 12 inches by (1, 12).

That means these points lie on the graph of the function 'f' represented by,

f(x) = a(b)ˣ

For the point (0, 16),

f(0) = a(b)⁰

16 = a(1)

a = 16

For another point (1, 12),

f(1) = a(b)¹

12 = ab

12 = 16(b) [Since a = 16]

b = \frac{12}{16}

b = \frac{3}{4}

Therefore, values of a and b are 16 and \frac{3}{4} respectively.

line segment connecting the vertices of a hyperbola is called the ________ ________, and the midpoint of the line segment is the
Lesechka [4]

line segment connecting the vertices of a hyperbola is called the <u>transverse axis</u> and the midpoint of the line segment is the <u>center</u> of the hyperbola.

What is transverse axis and center of hyperbola ?

The transverse axis is a line segment that passes through the center of the hyperbola and has vertices as its endpoints. The foci lie on the line that contains the transverse axis. The conjugate axis is perpendicular to the transverse axis and has the co-vertices as its endpoints.

And The center of a hyperbola is the midpoint of both the transverse and conjugate axes, where they intersect. Every hyperbola also has two asymptotes that pass through its center. As a hyperbola recedes from the center, its branches approach these asymptotes.

Learn more about the transverse axis and center of hyperbola here:

The formula for the surface area of a cube is A equal 6 s to the power of 2 comma where s is the side length. Cube X has a side
cricket20 [7]

Answer:

Surface area of Cube Y is 3 times greater than the surface area of cube X

Step-by-step explanation:

Surface area of a cube,A = 6s²

Where,

s = side length

Cube X has a side length of 1,

Surface area of cube, X = 6s²

= 6 * 1²

= 6 * 1

= 6

cube Y has a side length of 2

Surface area of cube, Y = 6s²

= 6 * 2²

= 6 * 4

= 24

How much greater is the surface area of cube Y than cube X?

Surface area of Cube Y is 3 times greater than the surface area of cube X

An electrician has 4.1 meters of wire how many strips 7/10 meter can he cut
spin [16.1K]
Turn 7/10 into decimal. (0.7)

Keep adding by 0.7 until you get the number closest to 4.1

3.5 is the closest, if we add another 0.7, we get 4.2.

So, he can get 5 sections of 0.7m
