Since ΔCDE is isosceles with base angles D and E equal then sides

CE = CD , hence

16x - 27 = 4x + 9 ( subtract 4x from both sides )

12x - 27 = 9 ( add 27 to both sides )

12x = 36 ( divide both sides by 12 )

x = 3

substitute x = 3 into the expressions for the sides

CD = (4 × 3 ) + 9 = 12 + 9 = 21

DE = (7 × 3 ) - 5 = 21 - 5 = 16

CE = (16 × 3 ) - 27 = 48 - 27 = 21

note that CE = CD

A quantity with an initial value of 600 decays exponentially at a rate of
Snowcat [4.5K]

Answer:

The value of the quantity after 87 months will be of 599.64.

Step-by-step explanation:

A quantity with an initial value of 600 decays exponentially at a rate of 0.05% every 6 years.

This means that the quantity, after t periods of 6 years, is given by:

Q(t) = 600(1 - 0.0005)^{t}

What is the value of the quantity after 87 months, to the nearest hundredth?

6 years = 6*12 = 72 months

So 87 months is 87/72 = 1.2083 periods of 6 years. So we have to find Q(1.2083).

Q(t) = 600(1 - 0.0005)^{t}

Q(1.2083) = 600(1 - 0.0005)^{1.2083} = 599.64

The value of the quantity after 87 months will be of 599.64.

If p(x) = 3x – 2and n (x) = 2x – 5, what is the value of (n/p) (1)?
Liula [17]

Answer:

-3

Step-by-step explanation:

We want (n/p)(1).  We can obtain this by finding n(1) and p(1) and then dividing as indicated:

p(1) = 3(1) - 2 = 1

n(1) = 2(1) - 5 = -3

Then   (n/p) (1) = -3/1, or just -3
