Answer: Choice D (aka 4th option)

C ' (-8, 1)

D ' (-6, 5)

E ' (-2, 4)

===========================================================

Explanation:

The x axis reflection rule is $(x,y) \to (x,-y)$

x stays the same while y flips in sign (positive to negative, or vice versa).

A point like C(-8, -1) will reflect to C ' (-8, 1)
The point D(-6, -5) reflects to D ' (-6, 5)
Lastly, the point E(-2, -4) reflects to E ' (-2, 4)

All of this points to Choice D as the final answer.

Answer:

last option is correct

Step-by-step explanation:

use formula of reflection over x axis .

The coordinates of C , D , E are (-8 , -1) , (-6 , -5) , (-2 , -4) respectively.

formula :

(x , y) = (x -y)

C(-8 , -1) = C'(-8 , 1)

D(-6 , -5) = D'(-6 , 5)

E(-2 , -4) = E'(-2 , 4)

A 10-pound block of ice melts at a rate of 3% per hour. Find the weight of the block of ice after 1 day.

mylen [45]

Answer:

The weight of the block of ice after 1 day is of 4.81 pounds.

Step-by-step explanation:

Equation for exponential decay:

The equation that models an amount after t hours, subject to exponential decay, is given by:

$A(t) = A(0)(1 - r)^t$

In which A(0) is the initial amount and r is the decay rate, as a decimal.

A 10-pound block of ice melts at a rate of 3% per hour.

This means that $A(0) = 10, r = 0.03$

$A(t) = A(0)(1 - r)^t$

$A(t) = 10(1 - 0.03)^t$

$A(t) = 10(0.97)^t$

Find the weight of the block of ice after 1 day.

One day has 24 hours, so this is A(24).

$A(24) = 10(0.97)^{24} = 4.81$

The weight of the block of ice after 1 day is of 4.81 pounds.

6's - 10 equal 2 + 3 S Plus s

Lorico [155]

6s - 10 = 2 + 3s + s

6s - 10 = 2 + 4s
6s - 4s = 2 + 10
2s = 12

s = 6

Is there more wood in a 60-foot-high tree trunk with a radius of 2.2 feet or in a 50-foot-high tree trunk with a radius of 2.6

Sladkaya [172]

Answer:

V₂=1061.85 ft³

Step-by-step explanation:

To determine where more wood is found, just find the volume of each log and see which one has the largest volume

knowing that the volume of a straight cylinder is

V=πR²h, where R=radius and h=height

$V_{1}=\pi (2.2)^{2}60= 912.31ft^{3}\\V_{2}=\pi (2.6)^{2}50= 1061.85ft^{3}$

As we can observe

V₂>V₁
