Answer:

BE = 266 2/3

PE = 233 1/3

Step-by-step explanation:

Part A: The figure has 3 triangles, all similar. In order of shortest-to-longest side lengths, they are ...

ΔBPE ~ ΔBCG ~ ΔGRE

Part B: They can be declared similar by the AA postulate. For BPE and BCG, the angles at B are vertical angles, so are congruent. The angles at C and G are alternate interior angles, so are congruent.

For triangles BPE and GRE, angle E is congruent to itself, The angles at R and P are corresponding angles, so are congruent.

(Remember, GRPC is a parallelogram, so any line in the figure is a transversal crossing parallel lines.)

Part C:

From parts A and B, we know ΔBPE ~ ΔBCG. Corresponding sides are proportional:

BP/BC = BE/BG = PE/CG

200/300 = BE/400 = PE/350

BE = (400)(2/3) = 266 2/3

PE = (350)(2/3) = 233 1/3

F(x)=5500(1.65) at what percent are the bacteria growing each hour

kodGreya [7K]

So exponenetial growth or decay

it goes like this
f(t)=P(1+r)^t
r=rate of decay or grouth
if r>0 then it is grouth by r
if r<0 then it is decay
i
P=initial amount
so
given
f(x)=5500(1.65)^t
f(x)=5500(1+0.65)^t
0.65>0 so it is growing by 65%

A boat is approaching a cliff known to be 40m tall. The angle of elevation is 30°. How far away is the boat from the cliff?

allochka39001 [22]

Answer:

x = 40 * $\sqrt{3}$ meters

Step-by-step explanation:

You have a 30-60-90 right triangle in this situation.

the height of this triangle is 40 meters

the opposite angle is 30 degrees.

use the tangent.

let x = distance between boat and cliff

tan 30 = 40/x

1/root (3) = 40/x

x = 40 * $\sqrt{3}$ meters

The function f(x) is graphed on the coordinate plane. What is f(−4) ?

elena-14-01-66 [18.8K]

For this type of problem, plug the -4 into the graph for x. So where is the line at x = -4??
y = 4 where x = -4.
That's the same as saying: "what is the y-value when x = -4?)
f(-4) = y = 4
