First: The student rotated the figure 90° clockwise.
Second: The student reflected across the x-axis.
Answer: Option C. <span>The student rotated the figure 90° clockwise rather than 90° counterclockwise.</span>
In order to get the answer to this problem, first we have to find out how many pounds does one case of pancake mix have. We know that one box has 1.3 pounds of pancake mix. We also know that one case has 12 boxes. So first, we multiply 1.3 to 12. The answer we will get is 15.6. One case of pancake mix has a total of 15.6 pounds of pancake mix. Now we also know there are 7.5 cases that George bought. So in order to get the total pounds George bought, we multiply 15.6 to 7.5. So all in all, George bought 117 pounds of Pancake Mix.
Answer:
D) 7.7 cm
Step-by-step explanation:
L/W=11cm/10cm=x/7cm
cross multiply to find x
10x=77
divide 10 by both sides
x=7.7
Answer: t = 6 s
Step-by-step explanation:
When Rose hit the water, the height of the jump is 0, so: h(t) = 0.
Resolving it, we have:
-16t² + 16t + 480 = 0
To simplify the second degree equation, divided it by 16:
-t² + t + 30 = 0
Now, solve the equation using Bhaskara:
Δ = 1² - 4. (-1) . 30
Δ = 1 + 120
Δ = 121
t = 
t₁ = 
= - 5
t₂ = 
= 6
Since time can be negative, it took t = 6s for Rose to hit the water.
Answer:
The approximate growth rate of the savings account is 2.5%
Step-by-step explanation:
Given the the function S(x) = 5, 000 * (1.025) ^ (0.7x)
From the function, we can see that part: (1.025). It presents for the growth factor or rate with the formula as:
(1 + r) where r is rate
So we have:
(1 + r) = 1.025
<=> r = 1.025 -1
<=> r = 0.025
In pecentage, we have the rare: 0.025 *100% = 2.5%
So the approximate growth rate of the savings account is 2.5%
