Find the sum of the constants a, h, and k such that

ra1l [238]

Answer:

Step-by-step explanation:

The value of "a" is the coefficient of x^2, so we know that is 2.

Solve for h

Now, we have ...

2x^2 -8x +7 = 2(x -h)^2 +k

Expanding the right side gives us ...

= 2(x^2 -2hx +h^2) +k

= 2x^2 -4hx +2h^2 +k

Comparing x-terms, we see ...

-4hx = -8x

h = (-8x)/(-4x) = 2

Solve for k

Now, we're left with ...

2h^2 +k = 7 = 2(2^2) +k = 8 +k

Subtracting 8 we find k to be ...

k = 7 -8 = -1

And the sum of constants a, h, and k is ...

a +h +k = 2 +2 -1 = 3

The sum of the constants is 3.

Lucas took his bike to a local park to ride on some bike trail.Trail A is 6 3/4 miles long.Trail B is 8 1/2 miles long. How many

Eddi Din [679]

Answer: Trial B is $1\dfrac{3}{4}$ miles longer then Trail A.

Step-by-step explanation:

Length of Trail A = $6\dfrac34$ miles

= $\dfrac{24+3}{4}$ miles = $\dfrac{27}{4}$ miles.

Length of Trail B = $8\dfrac12$ miles

= $\dfrac{16+1}{2}$ miles = $\dfrac{17}{2}$ miles.

Trial B is longer then Trail A by $\dfrac{17}{2}-\dfrac{27}{4}$ miles

$=\dfrac{17\times2}{2\times2}-\dfrac{27}{4}$ miles

$=\dfrac{34}{4}-\dfrac{27}{4}$ miles

$=\dfrac{7}{4}$ miles

$=1\dfrac{3}{4}$ miles

Hence, Trial B is $1\dfrac{3}{4}$ miles longer then Trail A.

a motorcyclist traveled a distance of 120 miles in 2 hours. traveling at the same speed how far would this motorcyclist travel i

olga_2 [115]

120/2 = x/5....120 miles to 2 hrs = x miles to 5 hrs
cross multiply
(2)(x) = (120)(5)
2x = 600
x = 600/2
x = 300....the motorcyclist would travel 300 miles in 5 hrs

or u could do it this way..
120/2 = 60 miles per hr
60 * 5 = 300 miles

Fred’s company is planning a new logo. The diagrams show two similar versions of the planned logo.

seraphim [82]

Answer:

a=7.2*1.5=10.8 cm

b=6.3/1.5=4.2 cm

$\pounds 4.48*2.25=\pounds 10.08$

Step-by-step explanation:

Proportional Geometric Shapes

A) We are given two similar shapes of a logo. They are to be proportional. We only need to find the proportion ratio of two of them to find the rest of the lengths.

The upper sides have 7.5 cm and 5 cm respectively. This gives us the ratio

$\displaystyle r=\frac{7.5}{5}=1.5$

Which means all the measures of the smaller logo are 1.5 smaller than those of the larger. This means

b=6.3/1.5=4.2 cm

a=7.2*1.5=10.8 cm

B) To paint the logos, we need to cover its surface, so the ratio of the surface is 1.5*1.5=2.25

This means the cost to paint the larger logo is

$\pounds 4.48*2.25=\pounds 10.08$
