Answer:

Sketch the graph of y=7x

Reflect the graph across the y-axis to show the function y=7^-x

Stretch the graph vertically by a factor of 3 to show the function y=3x7^-x

Shift the graph up 2 units to show the function y=3x7^-x +2

two similar containers have base areas 26cm² and 324cm² respectively. Calculate the capacity of the larger container correct to
Setler79 [48]

Answer:

351.9 cm³

Step-by-step explanation:

The ratio of the areas of two similar solids is equal to the square of the ratio of the lengths.

A₂ / A₁ = (s₂ / s₁)²

The ratio of the volumes of two similar solids is equal to the cube of the ratio of the lengths.

V₂ / V₁ = (s₂ / s₁)³

Therefore, we can say:

V₂ / V₁ = (A₂ / A₁)^(3/2)

Plugging in values:

V / 8 cm³ = (324 cm² / 26 cm²)^(3/2)

V = 351.9 cm³

How many terms are there in a geometric series if the first term is 2, the common ratio is 4, and the sum of the series is 2,730
Furkat [3]

Answer:

n = 6

Step-by-step explanation:

Givens

r = 4

a = 2

Sum = 2730

Equation

Sum = a(1 - r^n)/(1 - r)

Solution

2730 = 2 (1 - 4^n) / (1 - 4)      Reduce the denominator

2730 = 2(1 - 4^n)/-3                Multiply both sides by -3

2730*-3 = 2(1 - 4^n)                Simplify the left

-8190 = 2(1 - 4^n)                    Divide by 2

-8190/2 = 1 - 4^n                     Simplify

-4095 = 1 - 4^n                         Subtract 1 from both sides.

-4096 =  - 4^n                            Divide by - 1

4096 = 4^n                                This looks like n is fairly large. You could use logs. Try n = 6.

4^6 does equal 4096              So your answer is 6.

=========================

Let's try it with logs. Ignore this if you don't know how to do this.

log(4096) = log(4)^n

log(4096) = n*log(4)                    Divide by log 4

log(4096)/log(4) = n

3.6124 / 0.6021  = n

n = 6

========================

The hint is very helpful. Make sure you can follow it through

What is the measure of
Arturiano [62]

Answer:

Step-by-step explanation:

As BA = BC, this is an isosceles triangle and the angles adjacent the equal length legs are also identical.

∠C = ∠A = 56°

B = 180 - 2(56) = 68°
