A negative times a negative is a positive so...

( - ) ( - ) ( - ) ( -10x ) = -5

10x = -5

x = -5/10

x = -1/2

after 1 second the ball is 76 feet in the air: after 2 seconds it is 144 feet in the air. Find the height of the function. h(x)=

MArishka [77]

General equation for height, h
h = ut + 0.5gt^2

at t=1s, h = 76 feet
76 = u*1 + 0.5*a*1^2
76 = u + 0.5a

at t=2s, h = 144 feet
144 = u*2 + 0.5*a*2^2
144 = 2u + 2a
72 = u + a

Subtract 2 equations
0.5a = -4
a = -8
u = 80

So the equation,
h(x) = 80t + 0.5*(-8) t^2
h(x) = 80t - 4t^2

Find a formula for the nth term of the arithmetic sequence first term -17 common difference 5

hoa [83]

Given :-

First term of an AP is -17 .
Common difference is 5 .

To Find :-

The formula for the nth term .

Solution :-

We know that the nth term of an AP is given by ,

$T_n = a +(n-1)d$

where ,

a is the First term .
n is the number of the term .
d is the common difference .
T_n is the nth term .

On substituting the respective values we have ,

$T_n = -17 + (n -1)5 \\$

Open the brackets ,

$T_n = -17 + 5n - 5$

Simplify ,

$T_n = 5n -22$

Hence the nth term of the AP is given by 5n -22.

I hope this helps.

you are serving bratwurst and hamburgers at your annual picnic. you want at least three bratwurst and hamburgers for each of you

Varvara68 [4.7K]

B for Brats and H for Hamburgers
3 total for each of 30 guests
B + H = 3x30 = 90
Then $1.25B + $0.75H <= to $120
Solving for B=90-H
1.25B + 0.75(90-B) <=120 yields cost of B is $52.50 so B = 42.
90-42 = 48 H
So you can buy 42 Brats and 48 Hamburgers
