As the figure shows Elton runs 500 m to point b first then he turns 100 degrees and runs another 350 m to point c how far is the

Alex777 [14]

Answer:

658.24 m

Step-by-step explanation:

Let A be the point from where Elton started. Connect points A and C, you get triangle ABC with AB=500 m, BC=350 m and m∠B=100°. Use the cosine rule to determine the length of the segment AC:

$AC^2=AB^2+BC^2-2\cdot AB\cdot BC\cdot \cos \angle B,\\ \\AC^2=500^2+350^2-2\cdot 500\cdot 350\cdot \cos 100^{\circ},\\ \\AC^2=250000+122500-350000\cdot (-0.174),\\ \\AC^2\approx 433276.8622,\\ \\ AC\approx 658.24\ m.$

Find the surface area of the pyramid .The surface of the pyramid is _ in2 (Type a whole number .)

garik1379 [7]

Given the figure of a square pyramid

The area pf the base =area of the square of side 14 in =

$14\cdot14=196in^2$

the area of the sides = 4 times the area of a triangle of a base of 14 in and a height of 12 in

so, the area of the sides =

$4\cdot\frac{1}{2}\cdot\text{base}\cdot\text{height}=4\cdot\frac{1}{2}\cdot14\cdot12=336in^2$

So, the surface area of the pyramid =

$196+336=532in^2$

So, the answer will be A = 532 in^2

As a town gets smaller, the population of its high school decreases by 4% each year. The senior class has 320 students now. In

Mice21 [21]

Answer:

c(n) = 320·0.96^n
28 years

Step-by-step explanation:

Each year, the class size is multiplied by 1 - 4% = 96% = 0.96. After n years, it has been multiplied by that number n times. Repeated multiplication is signified using an exponent.

Class size (c) can be modeled by ...

c(n) = 320·0.96^n

You want to find n such that c(n) = 100. Put in that value and solve.

100 = 320·0.96^n

100/320 = 0.96^n . . . . . . . divide by 320

log(100/320) = n·log(0.96) . . . . . . . take logs

log(100/320)/log(0.96) = n ≈ 28.4932

In about 28 years, the class will have 100 students.
