Answer:
He can run 137.5 ft
Step-by-step explanation:
We can use a proportion to solve
55 ft x ft
--------------- = -----------------
10 seconds 25 seconds
55 *25 = x*10
1375 = 10x
Divide each side by 10
1375/10 = 10x/10
137.5 = x
He can run 137.5 ft
Answer:
C. 62.8 units
Step-by-step explanation:
Use distance formula or Pythagorean theorem.
Pythagorean-
6^2+8^2= radius^2
100= radius^2
10= radius
radius= r
Use circumference formula.
C=2pir
C=2pi10
C=62.83
To determine which of the statement is/are true, we simply have to evaluate the given choices.
a. f(x) = 0 when x = -1
f(x) = (-1)^3 - (-1)^2 - 4(-1) + 4
f(x) = 6
FALSE
b. f(x) divided by x - 1 has a remainder of 0.
f(x) = (1)^3 - (1)^2 - 4(1) + 4
f(x) = 1 - 1 - 4 + 4 = 0
TRUE.
c. (x - 1) is a factor of f(x)
Since, the division of f(x) by x - 1 gave an answer of zero this means that it is a factor.
TRUE.
d. f(-1) = 0.
In relation to letter a of this item, if we are to substitute -1 to x of the given equation, the answer is 6 instead of zero.
Answer:
1. 7.5
2. 7
3. 8
4. 1.44
5. 2
6. 4
Step-by-step explanation:
Use cross multiplication and then divide by the coefficient of x.
Here is how to solve number 1. Solve the rest of them like this.
2.5(15) = 5x
37.5 =5x
5 5
x=7.5
Please mark me brainliest and I hope this helps.
Do you mean 7?
You need to multiply each like term differently ( 1. Coefficient, 2. M term, 3. N term, and 4. O term)
1. The coefficients are 4 and 7, and as you have already solved, that equals to 28.
2. The m terms are (m • m) because there is one m in (4mno) and one m in (mn). m • m would equal to m^2.
3. The n terms are (n • n^2 •n) because there is one n in (4mno), n^2 in (7n^2o^2), and one n in (mn). They would equal n^4.
4. The o term would stay as o^2 as there are not other o terms.
To piece it all together, your answer would be 28m^2n^4o^2, or 28 • m ^2 • n^4 • o^2.
