Hey there! I'm happy to help!

We have the number -28 and we are subtracting 3 from it. This means we are going even further into the negatives, so it is -31.

Have a wonderful day! :D

Find the area of the triangles round to the tenth. Show steps please!
amm1812

Answer:

\large\boxed{A=89.6}

Step-by-step explanation:

It's the right triangle. The formula of an area of a right triangle:

A=\dfrac{leg\cdit leg}{2}

We have:

leg=x\\leg=16\\\text{and the angle}\ \alpha=55^o

Use tangent:

tangent=\dfrac{opposite}{adjacent}

opposite=16,\ adjacent=x

\tan55^o\approx1.4281

Substitute:

\dfrac{16}{x}=1.4281        <em>convert the decimal to the fraction</em>

\dfrac{16}{x}=\dfrac{14281}{10000}          <em>cross multiply</em>

14281x=160000            <em>divide both sides by 14281</em>

x=\dfrac{160000}{14281}

x\approx11.2

Calculate the area:

A=\dfrac{(16)(11.2)}{2}=89.6

A line passes through the points (7, 10) and (7, 20). Which statement is true about the line? It has a slope of zero because x 2
yaroslaw [1]

Answer:

It has no slope because x 2 minus x 1 in the formula m = StartFraction y 2 minus y 1 Over x 2 minus x 1 EndFraction is zero, and the denominator of a fraction cannot be zero.

Step-by-step explanation:

Points:

  • (7, 10) and (7, 20)

Slope-intercept form:

  • y= mx+b

slope is:

  • m= (y2-y1)/(x2-x1)= (20-10)/(7-7)= 10/0,

denominator of the fraction is zero, we can't divide by zero, so this line has no slope

----------

It has a slope of zero because x 2 minus x 1 in the formula m = StartFraction y 2 minus y 1 Over x 2 minus x 1 EndFraction is zero, and the numerator of a fraction cannot be zero.

  • no, numerator is not zero

It has a slope of zero because x 2 minus x 1 in the formula m = StartFraction y 2 minus y 1 Over x 2 minus x 1 EndFraction is zero, and the denominator of a fraction cannot be zero.

  • no, it has no slope

It has no slope because x 2 minus x 1 in the formula m = StartFraction y 2 minus y 1 Over x 2 minus x 1 EndFraction is zero, and the numerator of a fraction cannot be zero.

  • no, numerator is not zero

It has no slope because x 2 minus x 1 in the formula m = StartFraction y 2 minus y 1 Over x 2 minus x 1 EndFraction is zero, and the denominator of a fraction cannot be zero.

PLS HELP ME ASAP FOR 25!! (MUST SHOW WORK!!) + LOTS OF POINTS!!
Serggg [28]
If the rate at which the temperature fell is 4/5 degree/hour then we can simply multiply 5 hours to get our answer. 

4/5 * 5/1 = 20/5 = 4

So, it would change a total of 4 degrees.

I hope this helps. If something is confusing or this answer is wrong, don't be afraid to drop me a DM telling me what is wrong.

f(x)=x\left(3-\dfrac{4}{x+7}\right)=3x-\dfrac{4x}{x+7}=\dfrac{3x(x+7)}{x+7}-\dfrac{4x}{x+7}=\\=\dfrac{3x^2+21x-4x}{x+7}=&#10;\dfrac{3x^2+17x}{x+7}\\&#10;f'(x)=\dfrac{(6x+17)(x+7)-(3x^2+17x)}{(x+7)^2}\\&#10;f'(x)=\dfrac{6x^2+17x+42x+119-3x^2-17x}{(x+7)^2}\\&#10;f'(x)=\dfrac{119+42x+3x^2}{(x+7)^2}\Rightarrow \text{A}
