Answer:

First, finish the brackets, multiply what’s in the bracket by the outer side of the bracket

-24+12d=2d-6+22

Then, collect like terms

12d-2d=-6+22+24

10d=16+24

10d=40

d=40/10

d=4

Setler [38]

Answer:

$124.95

Step-by-step explanation:

The length of the strip is equal to perimeter of the kitchen.

P = 2(4.2 + 6.3) = 21 m

Cost of the strip is:

21*$5.95 = $124.95

Yet another math question

bonufazy [111]

Answer:

69.5

Step-by-step explanation:

Formula = 1/2 ( b1 + b2)h

base 1 + base 2 = 220

7645 x 2 = 14000 + 1200 + 80 + 10 = 15290

15290 / 220 = 764.5

H = 69.5

Lets check

1/2(220 x 69.5)

1/2(15290) = 7645

correct

Physics students were modeling the height of a ball once it was dropped from the top of a 10 foot ladder. The

julsineya [31]

Answer:

Interval notation: [0, 2.236]

Set Builder notation: $\{t\ |\ 0\le t\le 2.236\}$

Step-by-step explanation:

Given that:

Equation of height of the ball dropped from a height of 10 foot, as:

$h(t) = 10 - 2t^2$

Where $t$ is the time since the ball was dropped.

To find:

The domain of the function in Interval and set builder notation.

Solution:

Domain of a function is defined as the set of valid input values that can be given to the function for which the function is defined.

Here, input is time.

We can not have negative values for time.

Therefore, starting value for time will be 0 seconds.

And the value of height can not be lesser than that of 0 ft.

$0= 10 - 2t^2\\\Rightarrow 2t^2=10\\\Rightarrow t^2=5\\\Rightarrow t =2.236\ seconds$

Maximum value for time can be 2.236 seconds.

Therefore the domain is:

Interval notation: [0, 2.236]

Set Builder notation: $\{t\ |\ 0\le t\le 2.236\}$

Can someone please do this for me

Natasha_Volkova [10]

Next time please indicate which problem you want to work on.

One example of an equation with variables present on both sides is

y-b = m(x-a). Given the slope of a line and one point (a,b) through which the line passes, you can come up with an equation of the line.

Or, given the numeric value of y-b and that of x-a, you could obtain the slope of the line thru the points (x,y) and (a,b).
