Answer:

$t=\frac{b}{b+a}$

Step-by-step explanation:

we have

$t+\frac{at}{b}=1$

Solve for t

That means ----> Isolate the variable t

Multiply by b both sides to remove the fraction

$bt+at=b$

Factor the variable t in the left side

$t[b+a]=b$

Divide by (b+a) both sides

$t=\frac{b}{b+a}$

Use the formula a squared plus b squared =csquared in this case you will come out with an equation like this 3sqaured + bsqaured =12squared 9+bsqaured =144 144-9= b= 135 B=approximately 11.5

You have been asked to solve the system below. What method do you choose and why?

seropon [69]

Answer:

Elimination isn't exactly the easiest for this situation. But since the equations are in the same form and not solved for the same variable, I would go with elimination. (If they were solved for the same variable, I would go with substitution.) It would require me to make a manipulation on both equations.

I would multiply first equation by 5 and second equation by -2. The reason I would do this is because the y's would have opposite coefficients and when you add opposites you get 0.

The new set of equations would look like this:

20x+10y=45

-14x-10y=2

But I will slope here since we aren't asked to solve it.

Some texts use the term linear combination instead of elimination. They are the same.

A stem and leaf plot titled High Temperatures in degrees Fahrenheit. The stems are 4, 5, 6, 7. The first column of leaves are 9,

ad-work [718]

Answer:

The temperature with the highest frequency is 54

Step-by-step explanation:

Given

The above data

Required

The temperature with the highest frequency

The first step, is to plot the stem and leaf plot.

$\begin{array}{cc}{4} & {9\ \ } & {5} & {2\ 4\ 4\ 6\ 8} & {6} & {0\ 1\ } & {7} & {2\ 3\ } \ \end{array}$

Next, is to identify the leaf with the highest frequency.

The leaf is 4 (with frequency 2)

Next, is to identify the accompanying stem of the leaf

The stem is 5

<em>Hence, the temperature with the highest frequency is 54</em>

What is the minimum value of the graph of y=sin x assumes

Alex

Short answer: - 1
The first thing you should do is draw this or get a program to do it. I use desmos. It is included. The graph shows one complete cycle every 2*pi intervals (or 360 degrees.)

You will find no lower value that y = - 1 (nor any value greater than y = 1)

The lengths of the sides of triangle XYZ are written in terms of the variable m, where m ≥ 6.

ankoles [38]

Answer:

$m\angle Y$

Step-by-step explanation:

In triangle XYZ, the lengths of sides are

$XY=m+8;$
$YZ=2m+3;$
$XZ=m-3.$

If $m\ge 6,$ then

$m+8\ge 14;$
$2m+3\ge 15;$
$m-3\ge 3$

and

$m-3\le m+8\le 2m+3$

The greatest angle is opposite to the greatest side, the smallest angle is opposite to the smallest side, so

the greatest side is $YZ=2m+3$ - the greatest angle is $\angle X;$
the smallest side is $XZ=m-3$ - the smallest angle is $\angle Y.$

Thus,

$m\angle Y$
