Bob is trying to calculate the area of a triangle with a base of 5 meters and a height of 7 meters. He mistakenly switches the h

ehidna [41]

Answer:

see below

Step-by-step explanation:

A = 1/2 b*h

A = 1/2 (5*7)

We can use the commutative property of multiplication which states

a*b = b*a

A = 1/2 (7*5)

This will not affect the answer because 5*7 = 7*5

For problems 1, 2, and 3, use the function g(x) = sin(6x) .

Fantom [35]

Step-by-step explanation:

1. Amplitude = 1. g(x) = 1 sin(6x). The coefficient 1 is the amplitude. The range of the function is $-1 \le g(x) \le 1$ or, in interval notation, [-1, 1]

2. The period is $\frac{2\pi}{6}=\frac{\pi}{3}$ .

x-intercepts (at the beginning, middle, and end of the period) $0,\,\frac{\pi}{6},\,\frac{\pi}{3}$

Maximum (1/4 of way through period) $\left(\frac{\pi}{12},\,1 \right)$

Minimum (3/4 of way through period) $\left( \frac{\pi}{4}, \, -1 \right)$

A certain forest covers an area of 2100 km². Suppose that each year this area decreases by 3.5%. What will the area be after 5 y

Blizzard [7]

Answer:

$\large\boxed{\sf \ \ \ 1757 \ km^2 \ \ \ }$

Step-by-step explanation:

Hello,

<em>I would recommend that you checked the answers I have already provided as this is the same method for all these questions, and maybe try to solve this one before you check the solution.</em>

<u>At the beginning the area is 2100</u>

<u>After one year</u> the area will be

2100*(1-3.5%)=2100*0.965

<u>After n years</u> the area will be

$2100\cdot0.965^n$

So after 5 years the area will be

$2100\cdot0.965^5=1757.34027...$

So rounded to the nearest square kilometer is 1757

Hope this helps

A boat uses two pontoons to float. Each pontoon consists of a cylinder with a hemisphere at each end, as shown. Find the total v

zubka84 [21]

Answer:

$Total \approx 20ft^3$

Step-by-step explanation:

Given

$h = 12ft$ --- height of the cylinder

$d =1ft$ --- the diameter of the hemispheres at both end and the cylinder

See attachment for pontoon

Required

Determine the volume

First, calculate the radius (r)

$r = \frac{1}{2} * d$

$r = \frac{1}{2} * 1ft$

$r = 0.5ft$

Next, the volume of the cylinder

$V_1 = \pi r^2h$

$V_1 = 3.14 * 0.5^2 * 12$

$V_1 = 9.42ft^3$

Two hemispheres make up a sphere. So, we simply calculate the volume of a sphere.

$V_2 = \frac{4}{3}\pi r^3$

$V_2 = \frac{4}{3} * 3.14* 0.5^3$

$V_2 = 0.52ft^3$

So, the volume of 1 pontoon is:

$V_3 = V_1 + V_2$

$V_3 = 9.42ft^3 + 0.52ft^3$

$V_3 = 9.94ft^3$

The volume of both is:

$Total = 2 * V_3$

$Total = 2 * 9.94ft^3$

$Total = 19.88ft^3$

$Total \approx 20ft^3$
