Answer:
89.0
Step-by-step explanation:
One way to round a number is to add half the place value you're rounding to, then truncate at the desired place value.
Here, we want to round to a tenth (0.1), so we first add half that value:
88.98 + 0.05 = 89.03
Now, we throw away all digits after the tenths place.
89.0 . . . . our rounded value

You have 2 cups of ketchup. You need 2 Tbsp to make one serving of barbecue sauce. How many servings can you make?
Here we need to perform a change of units to see how many servings can we make. We will see that we can make 48 servings.
Change of units:
We know that we have 2 cups of ketchup and we need 2 tbsp to make a serving, so to see the total number of servings that we can make, we need to see how many teaspoons we have in 2 cups.
We can use the relation:
1 cup = 48 teaspoons.
Then:
2 cups = 2*(48 teaspoons) = 96 teaspoons.
And we need 2 per serving, then we can make a total of:
96/2 = 48 servings.

Given cos x=12/13 and sinx=5/13. What is ratio for tan x ?
Answer:
5/12
Step-by-step explanation:
tan(x)=sin(x)/cos(x)
So by substitution we have
tan(x)=(5/13)/(12/13)
Multiplying numerator and denominator by 13 gives
tan(x)=5/12

The unit circle with center at the origin is a relation but not a function.
a. Find the two functions which are semicircles of the unit circle, and determine
their domains and ranges?
b. Are these functions onto functions? Justify.
c. Find the two functions which are lie in one of the semicircle in part a, and
determine their domains and ranges?
d. Are these functions one to one correspondence functions? Justify.
Step-by-step explanation:
the formula of the "relation" is
x² + y² = r²
this is for circle with its center at the origin.
now that gives us
y² = r² - x²
y = ±sqrt(r² - x²)
a. this ± of the square root gives us the 2 functions.
y = sqrt(r² - x²)
y = - sqrt(r² - x²)
as it is a circle, the ranges and domains are the same.
domain is the allowed number interval for x, and range is the number interval for y (the function results).
both are
-r <= x <= r
outside of that range the square root argument becomes negative, and that is undefined for R (the set of real numbers).
b. if we want to see it that way, we can say that
f(x) = r² - x²
g(x) = sqrt(x)
and so
sqrt(r² - x²) = g(f(x))
a function into function.
c. let's pick the "positive" semicircle
y = g(f(x)) = + sqrt(r² - x²)
f(x) = r² - x²
the domain is all x (-infinity < x < +infinity)
the range is (-infinity < y <= r²), as negative and positive larger x will turn f(x) negative. the functional results cannot get bigger than r² (for x=0).
g(x) = +sqrt(x)
the domain is all positive x incl. 0 (0 <= x < +infinity), as sqrt is not defined for negative values. at least not in R.
the range is also all possible positive values incl. 0
(0 <= y < +infinity).
d.
A one-to-one correspondence function is a function between the elements of the two sets of domain and range, where each element of one set is paired with exactly one element of the other set, and each element of the other set is paired with exactly one element of the first set.
that means, every x value creates exactly one y value, and no y value occurs more than once.
this is no true for
f(x) = r² - x²
because for -r <= x <= r we get the same y for -x and +x.
it is true for
g(x) = sqrt(x), as no 2 different numbers have the same square root.

Answer:
1. 80 or D
2. 18 or A
Step-by-step explanation:
well if a triangle is 400 square inches that mean the area is 400 and we know that the formula for area of a triangle is 1/2bh. we can do 400 = 10h/2 and now we solve for h. so times by 2 to get 800 = 10h and divide by 10 to get 80 inches. now substitute 80 in the equation and you get 400. so the answer is true.
for the second one the area of a trapezoid is (b_1+b_2)/2 • h so we substitute again to get 342 = 38h/2. now we can times by 2 to get 684 and divide by 38 to get 18. or you can do 19h = 342 and get 18.
now if you substitute the 18 in the equation you end up with 342. so the answer is true

Dave's family went to the beach. They got to the beach at 1:45 P.M. and swam in the ocean
for 1 hour and 13 minutes. Then they built sand castles for 35 minutes and played volleyball
for 1 hour and 35 minutes before heading home. What time was it when Dave's family left
the beach?
Answer:
5:08 PM
Step-by-step explanation:
1:45 plus 1 hour and 13 minutes equals 2:58. 35 minutes added to 2:58 equals 3:33. Finally 3:33 PM added to 1 hour and 35 minutes equals 5:08 PM.

Which of the following is a common multiple of 4 and 10?
A 100
B 104
C 90

Answer:
A) 100
Step-by-step explanation:
When looking for a common you can move up the times tables of each number until you find a matching pair. 10x10=100 and 4x25=100. By looking for common answers through the times tables you can more easily find a common multiple.

Answer:
f(x) | 5 | - 1 | - 3 | - 1 | 5 |
Step-by-step explanation:
So first you'll say "-2" into function
Replace x with negative 2
f(x) =2(-2) ^2 - 3
8 - 3 = 5
Secondly place "- 1" into function
Replace x with negative 1
f(x) = 2(-1)^2 - 3
2 - 3 = - 1
Thirdly place "0" into function
Replace x with 0
f(x) = 2(0)^2-3
0 - 3 = - 3
Then place "1" into function
Replace x with 1
f(x) = 2(1)^2 - 3
2 - 3 = - 1
Lastly place "2" into function
Replace x with 2
f(x) = 2(2)^2 - 3
8 - 3 = 5
