Answer:

In the number 105, there are 10.5 tens.

Step-by-step explanation:

To take this into more simply matters, you can simply count by tens until you get the number wanted or the closest number below it. Follow along below -

10, 20, 30, 40, 50, 60, 70, 80, 90, 100.

When adding another 10, you get 110. Therefore, you can't go to that level.

From the numbers listed above, you see that there are ten. However, we haven't gotten to 105 yet. Since 5 is five more than 100, and that is 5 of a whole another set of 10, we would express it as 1/2, or .5. You would add this to your group of 10s, making it 10.5. Hope this helped!

Answer:

Time spent on professional calls is typically shorter but less consistent than time spent on personal calls.

Step-by-step explanation:

Professional calls are typically shorter (Median = 4 min) than personal calls (Median = 5 min).

However, they are less consistent (IQR = 5 min) than personal calls (IQR = 2 min).

What is the solution of the equation sqrt b-17 + sqrt b=1?

Inga [223]

Answer:

no solution.

Step-by-step explanation:

The given equation is

$\sqrt{b-17}+\sqrt{b}=1$

$\mathrm{Subtract\:}\sqrt{b}\mathrm{\:from\:both\:sides}\\\sqrt{b-17}+\sqrt{b}-\sqrt{b}=1-\sqrt{b}$

On simplifying, we get

$\sqrt{b-17}=1-\sqrt{b}$

Squaring both sides

$\left(\sqrt{b-17}\right)^2=\left(1-\sqrt{b}\right)^2\\\\b-17=1-2\sqrt{b}+b$

Subtract b from both sides

$17=1-2\sqrt{b}$

On simplifying, we get

$-18=-2\sqrt{b}$

Squaring both sides

$324=4b\\\\b=81$

Now, we substitute this value in the original equation

$\sqrt{81-17}+\sqrt{81}=1\\\\\sqrt{64}+9=1\\\\8+9=1\\\\17=1\text{ This is False}$

Hence, b = 81 is an extraneous solution.

Therefore, the given equation has no solution.

Use synthetic substitution to find g(4) and g(-5) for the function g(x) = 3x4 - 5x2 + 7x - 7

nevsk [136]

Answer:

$g(4)=709$

$g(-5) = 1708$

Step-by-step explanation:

Step 1: Find g(4)

Substitution Method:

$g(4)=3(4)^4-5(4)^2+7(4)-7$

$g(4)=3(256)-5(16)+28-7$

$g(4)=768-80+28-7$

$g(4)=709$

Synthetic Division:

$\begin{array}{rrrrrr}\multicolumn{1}{r|}{4} & {3} & 0 & -5 & 7 & -7\\\cline{2-6} & & 12& 48 & 172 & 716\\\cline{2-6} & 3 & 12& 43 & 179 & \multicolum{|} 709\end{array}$

Answer: $g(4)=709$

Step 2: Find g(-5)

$g(-5)=3(-5)^4-5(-5)^2+7(-5)-7$

$g(-5)=3(625)-5(25)-35-7$

$g(-5) = 1875-125-35-7$

$g(-5) = 1708$

Synthetic Division:

$\begin{array}{rrrrrr}\multicolumn{1}{r|}{-5} & {3} & 0 & -5 & 7 & -7\\\cline{2-6} & & -15& 75& -350& 1715\\\cline{2-6} & 3 & -15& 70& -343& \multicolum{|} 1708\end{array}$

Answer: $g(-5) = 1708$
