Answer:

(x, y ) → (x + 4, y - 1 )

Step-by-step explanation:

Consider the coordinates of K and K'

K (- 3, 5 ) , K' (1, 4 )

x- direction : - 3 → 1 is + 4 units to the right

y- direction : 5 → 4 is - 1 units down

translation rule is (x, y ) → (x + 4, y - 1 )

38. What is the surface area of a conical grain storage tank that has a height of 62 meters and a diameter of 24 meters? Round t
svetoff [14.1K]
1. The surface area of a cone S is S= \pi  r^{2}+  \pi rl, where r is the radius of the base and l is the slant height.

2. The slant height l is found as follows:

l^{2}= OC^{2}+ OB^{2}
l^{2}= 12^{2}+ 62^{2}=144+3844=3988

l= \sqrt{3988}=63.15

3. 

A=\pi r^{2}+ \pi rl=3.14(12)^{2}+3.14*12*63.15

= 452.16+2379.492 =2831.652 ( m^{2} )

 = 452.16+2379.492 =2831.652 ( m^{2} )

4. The answer is C

Create a question with this scenario you could ask that could be answered only by graphing or using logarithm.
Vesnalui [34]

Answer:

After how many years is the fish population 100?

x=3.97 years

Step-by-step explanation:

The fish population increases by a factor of 1.5 each year. We have the equation that represents this situation

f (x) = 20 (1.5) ^ x

Where x represents the number of years elapsed f(x) represents the amount of fish.

Given this situation, the following question could be posed

After how many years is the fish population 100?

So we do f (x) = 100 and solve for the variable x

100 = 20 (1.5) ^ x\\\\\frac{100}{20} = (1.5)^x\\\\ 5= (1.5)^x\\\\log_{1.5}(5) = log_{1.5}(1.5)^x\\\\log_{1.5}(5) = x\\\\x =log_{1.5}(5)\\\\x=3.97\ years

Observe the solution in the attached graph

X = 1
y = -4
xy = (1)(-4) = -4

answer
C) -4


double check:
y - 4  = 4x + 3y = -(9-x)
-4 - 4 = 4(1) + 3(-4) = -(9 - 1)
    - 8 =   -8              = -8
