Answer:

25.92 foot strides

Step-by-step explanation:

The man will take 120/5 = 24 five foot stride to cover the initial 120 foot advantage of the child.

Within this time, the child would have covered an additional 24/5 x 2 = 9.6 extra foot stride.

Within this 9.6 food stride of the child, the man will have to take an additional 9.6/5= 1.96 strides.

Total foot stride by the man will be 24 + 1.96 = 25.92 foot strides.

Which is the completely factored from of xy^3-x^3y
Oksanka [162]

Answer:

xy(y+x)(y-x)

Step-by-step explanation:

To factor the expression, remove the greatest common factor or GCF from each term. Both terms share in common xy. The expression becomes:

xy^3-x^3y\\xy(y^2-x^2)

What remains in the parenthesis is a different of perfect squares. Factor the difference of perfect squares into two binomials of the form (x+a)(x-a) where a is the square root of (x^2-a^2).

So the expression becomes:

xy(y^2-x^2)\\xy(y+x)(y-x)

Which is the correct answer?
Nataly [62]

Answer:

lolooollollolololo-

jk

The answer is

J) 334.06

Step-by-step explanation:

We know the rate is 1.5 inch an hour

So 1.5*2.54 is 3.81

Now 3.81 cm every hour

24 hours a day

3.81*24=91.44

Now 91.44 cm A day

1 Year or 365 days

91.44*365= 33375.6cm a year

now we also need to add the extra 12 inches in the beginning

12*2.54=30.48cm

Now add those 2

33375.6+30.48= 33406.08

now the answer asked for meters so we divide 33406.09/100

you’ll get 334.06 or J

Evaluate the expression for x2 +y2 for x =-5 and y = -2​
MrMuchimi
If that’s supposed to be x squared and y squared then it would be: -5^2 + -2^2=29

If it’s x and y multiplied by 2 then the answer would be (-5 x 2) + (-2 x 2) = -14.

Graph the relation. Is the relation a function? Why or why not? {(0, 1), (3, 5), (2, 2), (–1, 4)}
vagabundo [1.1K]

Answer:

It is a function.

Step-by-step explanation:

This relation <u>is</u> a function because it does not repeat any x values in the set of data points.

A function is a set of points where the input values, or x values, do not repeat themselves.

Hope this helps!
