Solving a One-Variable Linear Equation

Answers

Answer:

[tex]\Longrightarrow:\boxed{\sf{h=14}}[/tex]

Step-by-step explanation:

Isolate the term of h from one side of the equation.

Use the distributive property.

Distributive property:

→ A(B+C)=AB+AC

7h-5(3h-8)=-72

First, multiply expand.

⇒ -5(3h-8)

⇒ -5*3h=-15h

⇒ -5*8=40

Rewrite the problem.

→ -15h+40

⇒ 7h-15h+40=-72

⇒ 7h-15h=-8h

→ -8h+40=-72

Subtract by 40 from both sides.

⇒ -8h+40-40=-72-40

Solve.

⇒ -72-40=-112

⇒ -8h=-112

Then, you divide by -8 from both sides.

⇒ -8h/-8=-112/-8

Solve.

Divide the numbers from left to right.

→ -112/-8=14

[tex]\Longrightarrow: \boxed{\sf{h=14}}[/tex]

Therefore, the correct answer is h=14.

A ball is thrown from an initial height of 2 meters with an initial upward velocity of 15 m/s. The ball's height h (in meters) after t seconds is given by the following.

Answers

To find when the ball's height is
7
meters, we substitute
7
for
h
and solve for
t
.
=7+2−25t5t2
In order to solve for
t
, we first rewrite the equation in the form
=+at2+btc0
.
=+−5t225t50
Next, we use the quadratic formula to solve for
t
.
=t−b±−b24ac2a
Our equation has
=a5
,
=b−25
, and
=c5
.
Another way
We use these values in the formula.
t
=−−25±−−252·4·55·25
=25±52510
We get that
t
can be either of two values to solve the equation.
=t=−25525100.2087…
or
=t=+25525104.7912…
Rounding these values to the nearest hundredth, we get
=t0.21
or
=t4.79
.
So, the ball's height is
7
meters at approximately
0.21
seconds (on its way up) or
4.79
seconds (on its way down).

This is easy....

First, the frequency is how many times a number or certain value in a set of data appears...

So basically, its asking you for the number of times that a number in between 0 and 9 appears in the data set:

23, 15, 18, 11, 30, 32, 47, 5, 9, 10, 0, 34, 39, 49, 9

To make this easier, we can put them in numerical order.

0,5,9,9,10,11,15,18,23,30,32,34,39,47,49

Now, just single out the numbers before 10.

0,5,9,9

4 numbers, so its 4. The number of times a number between 0 and 9 appears in the data set is 4. That goes in the Frequency side...

Alright, Nancy, let's do this.

If dimes are d, then quarters is d + 3.

10d + 25(d + 3) = 1090

I'm dealing with cents to get rid of the pesky decimal.

10d + 25d + 75 = 1090

                    35d = 1015

Since quarters = d + 3, there are 32 quarters and 29 dimes.

what polynomial must be added to 3xsquared + 4x+7 to obtain a sum of zero

Answers

The polynomial which must be added to 3x² +4x + 7 to obtain a sum of 0 is; -3x² -4x +7.

Let the polynomial which must be added to 3x² +4x + 7 to obtain a sum of 0 be represented by P.

In essence;

P + 3x² +4x + 7 = 0.

By subtracting 3x² +4x + 7 from both sides of the equation to obtain the value of P; we have;

P = 0 -3x² -4x +7.

Ultimately, P = -3x² -4x +7.

An astronaut drops a hammer on the Moon as part of an experiment. Before the drop, he raises the hammer by a height of 1 m, which increases its gravitational potential energy by 1.2 J. The mass of the hammer is 0.75 kg. Calculate the gravitational field strength on the Moon.

Answers

Answer:

  1.6 N/kg

Step-by-step explanation:

The units of gravitational field strength are newtons per kilogram. The joule is a derived unit equivalent to a newton·meter.

Then the field strength is ...

  newtons/kg = (1.2 N·m)/((1 m)(0.75 kg)) = 1.6 N/kg

Find the formula for an inverse proportion, knowing that its graph goes through the point: A(8, 0.125) PLEASE EXPLAIN WELL! THANK YOU

Answers

The formula for the given inverse proportion is:

y = 1/x

How to get the formula of the inverse proportion?

The general formula of an inverse proportion is written as:

y = k/x

Where k is the constant of proportionality.

In this case, we know that the point (8, 0.125) belongs to the graph, then replacing these values on the general formula we get:

0.125 = k/8

Solving for k we get:

0.125*8 = k = 1

Then the inverse proportion is:

y = 1/x
