Answer:
what graph?...........
A rock is thrown from the top of a ladder. The function
h(t) = –16t2 + 120t + 10 gives the height of the rock t seconds after it is
thrown a certain number of feet.
What is the height of the rock at 5 seconds?
Answer:
h'(t)=88
Step-by-step explanation:
h'(t)=d/dt (-16t x 2 + 120t + 10
h'(t)=d/dt (-32t + 120t + 10)
h'(t)=d/dt (88t + 10)
h'(t)=d/dt (88t) + d/dt (10)
h'(t)=88 + 0
what is 457.894 to 2 deimal places
Answer:
228.947
Step-by-step explanation:
Answer:
457.894
Step-by-step explanation:
"What is 457.894 rounded to 2 decimal places?" is the same as asking, "What is 457.894 rounded to two decimal points?" or "How to round 457.894 to two decimal places."
The main point is that you want to round 457.894 to two digits or places after the decimal point. Thus, we want to eliminate the last digit in 457.894. To eliminate the last digit in 457.894, we use the following Two Decimal Places Rules to get the answer:
Two Decimal Places Rule #1: If the last digit in 457.894 is less than 5, then remove the last digit.
Two Decimal Places Rule #2: If the last digit in 457.894 is 5 or more and the second to the last digit in 457.894 is less than 9, then remove the last digit and add 1 to the second to the last digit.
Two Decimal Places Rule #3: If the last digit in 457.894 is 5 or more and the second to the last digit in 457.894 is 9, and the third to the last digit is less than 9, then remove the last digit, make the second to last digit 0, and add 1 to the number to the third to the last digit.
Two Decimal Places Rule #4: If the last digit in 457.894 is 5 or more and the second to the last digit is 9, and the third to the last digit is 9, then add 1 to the number on the left side of the decimal point and make the right side of the decimal point 00.
When rounding 457.894 to two decimal places we use Two Decimal Places Rule #1. Therefore, the answer to "What is 457.894 rounded to 2 decimal places?" is:
457.89A farmer has 280 acres of land on which he plans to plant two different crops, crop A and crop B. For each acre of crop A he plants, his expenses are $25, and for each acre of crop B, his expenses are $30. The farmer has a limit of $10,000 for the expenses of planting the 280 acres. If a represents the acres of crop A and b represents the acre of crop B that the farmer plants, which of these represent the limits of a and b?

Emma goes miniature golfing. She pays $7.50 for an admission ticket and $6.25 for each round she golfs. The total amount Emma pays for admission and the number of rounds she golfs is $26.25. Which equation can be used to determine the number of rounds, x, that Emma golfs?
Answer:
The equation that can be used to determine the number of rounds that Emma golfs is:
x=(c-7.50)/6.25
Step-by-step explanation:
From the information given, the total amount Emma pays to go miniature golfing is equal to the price of the admission ticket plus the result of multiplying the price per round of golf for the number of rounds and according to this, the equation would be:
c=7.50+6.25x, where:
c is the total cost for Emma to go miniature golfing
x is the number of rounds
Now, you can solve for x to determine the equation that can be used to find the number of rounds that Emma golfs:
x=(c-7.50)/6.25
You can replace c with 26.25:
x=(26.25-7.50)/6.25
x=18.75/6.25
x=3

kilometers to the mountain's peak. How tall is the mountain?
Answer:
4.3068
Step-by-step explanation:

Answer:
= 4.39km
Step-by-step explanation:
Camp distance = 1.48Km
Distance travelled afterwards = 2.91km
Mountain Height = total distance travelled
So total distance = 1.48 + 2.91
= 4.39km -----------> final answer

Two sides of a triangle have lengths 8 and 16. Which expression describes the length of the third side?
greater than 8 and at most 24
at least 8 and at most 24
at least 8 and less than 24
greater than 8 and less than 24
Answer:
Based on the given description above, the correct answer would be the second statement. If two lengths of two sides of a triangle are 9 and 15, therefore, the length of the third side must be greater than or equal to 6 and at most 24. Hope this answer helps.
