The table represents an exponential function.

Mathematics
1 answer:
Mama L [17]2 years ago
3 0

Answer:

Step-by-step explanation:

All we are doing here is solving for the b in

y=a(b)^x, which is the standard form for an exponential function.

Use the first 2 coordinate pairs to solve for b: (1, 6) and (2, 4):

6=a(b)^1 so

a=\frac{6}{b} and use that when you write the next equation using the next coordinate pair:

4=\frac{6}{b}(b)^2 which simplifies to

4 = 6b so

b=\frac{2}{3}, the second choice there. Another way of saying multiplicative rate is the rate of decay or the rate of growth. Same thing. This is decay since 2/3 is greater than 0 but less than 1.

The legs of a right triangle are 12 cm and 16 cm. What is the length of the hypotenuse? 15 cm 17 cm 20 cm 28 cm
GalinKa [24]
Answer: 20 cm

To solve this, use the Pythagorean Theorem, a² + b² = c², where a and b are the legs of the right triangle, and c is the hypotenuse of the right triangle.
**The Pythagorean Theorem only works for right triangles.**

Substitute in the values.
a² +  b² = c²
12² + 16² = c²

Solve for c, the hypotenuse.
12² + 16² = c²               
144 + 256 = c²
400 = c²
c = √400
c = 20

Use the given x and y values to write a direct variation<br> equation.<br> x = 2, y = 30
exis [7]

Answer:

y = 15x

Step-by-step explanation:

Given x and y are in direct variation then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition x = 2, y = 30, then

30 = 2k ( divide both sides by 2 )

15 = k

y = 15x ← equation of variation
