I think it would be easier to covert the fractions to decimals here

-1.2 * 1 1/5 / 3/10

= -1.2 * 1.2 / 0.3

= -1.44 / 0.3

= - 4.8 answer

The new office should be at a distance of 37.5 miles from Jonesville.

The weighted mean is the sum of all elements in a data-set multiplied by their weights, divided by the sum of the weights. For example, if x1 and x2 are the elements with weights w1 and w2 respectively, then the weighted average is calculated using the given formula-

M = {(x1*w1) + (x2*w2)}/ (w1+w2)

Here, we are given that two cities Jonesville and Bellevue, 60 miles apart.

Let Jonesville be at point 0 and Bellevue be at point 60.

Jonesville has a weight of 3 and Bellevue has a weight of 5.

Thus, the weighted average can be calculated as follows-

Mean = {(60*5) + (0*3)}/8

= 300/8

= 75/2

= 37.5

Thus, the new office should be at a distance of 37.5 miles from Jonesville.

Which statement best describes the graph of this polynomial function f(x)=x^4+x^3-2x^2

jenyasd209 [6]

Answer:

See below description.

Step-by-step explanation:

The function $f(x) = x^4+x^3-2x^2$ has the following characteristics:

Factors: $x^2(x+2)(x-1)$
Zeros/roots: x=0, x=-2, amd x=1
Positive leading coefficient
Graph starts up, curves down through -2 on the x-axis and back up to 0 where it touches and curves down and back up again again. It comes down back through 1 and crosses.
Its graph s the shape of a W.
It has minimum values at -2.83 and -0.397

Eva8 [605]

Answer:

B.) 7 in

Step-by-step explanation:

A regular hexagon can be divided into 6 congruent equilateral triangle. The measure of an angle of an equilateral triangle is 60 deg. The angle formed by sides b and c measures 60 deg.

tan A = opp/adj

tan 60 deg = 12/b

b * tan 60 deg = 12

b = 12/(tan 60 deg)

b = 7 in

Jason divides his first 1/2 mile of the trail into 3 sections. He puts a sign at the end of each section. If the signs are an eq

Blizzard [7]

Answer:

1/6 mile

Step-by-step explanation:

Distance divided = 1/2 miles

No of sections = 3

Each division must equal = 1/2/3

= 1/2*1/3 = 1/6 mile.

The distance between each of the signs i.e between the first and second , second and third is 1/6 of the mile.

This can be done in decimals as well

1/2 mile= 0.5 mile.

When we divide 0.5 mile by 3 we get 0.167 which is equal to 1/6 in fractions.
