Francine and Cheryl received equal scores on a test made up of multiple choice questions and an essay. Francine got 34 multiple

kipiarov [429]

$34x + 14 = 30x + 22$
X is the amount the multiple choice question is worth. Both girls had the same test score so both are equal. Isolate X and that will be the value.

$34x -( 30x) + 14 = 22$
$4x = 22 - (14)$
$4x = 8$
$4x \div 4 = 8 \div 4$
x = 2

Plug 2 back in for x in the original equation to check and both girls recieved a 82%

How do I do this and whats the answer please

stepladder [879]

Answer:

slope= - 3/4

A(-4,3) and B(4,-3)

$slope=m=\frac{y_B-y_A}{x_B-x_A} =\frac{-3-3}{4-(-4)} =\frac{-6}{8} =-\frac{3}{4}$

Can I get help answering this question? It's a derivatives question, further info in the attachment.

Nadusha1986 [10]

$\bf f(x)=|3+9x|\implies f(x)=\sqrt{(3+9x)^2}\implies f(x)=[(3+9x)^2]^{\frac{1}{2}}
\\\\\\
\cfrac{dy}{dx}=\stackrel{chain~rule}{\cfrac{1}{2}[(3+9x)^2]^{-\frac{1}{2}}\cdot 2(3+9x)\cdot 9}\implies \cfrac{dy}{dx}=\cfrac{9(3+9x)}{[(3+9x)^2]^{\frac{1}{2}}}
\\\\\\
\cfrac{dy}{dx}=\cfrac{27+81x}{|3+9x|}\\\\
-------------------------------$

$\bf \textit{left-hand derivative at }x=-\frac{3}{9}\implies \cfrac{27+81x}{-(3+9x)}
\\\\\\
\cfrac{27+81\left( -\frac{3}{9} \right)}{-3-9\left( -\frac{3}{9} \right)}\implies \cfrac{27-27}{-3+3}\implies \stackrel{unde fined}{\cfrac{0}{0}}\\\\
-------------------------------\\\\
\textit{right-hand derivative at }x=-\frac{3}{9}\implies \cfrac{27+81x}{+(3+9x)}
\\\\\\
\cfrac{27+81\left( -\frac{3}{9} \right)}{3+9\left( -\frac{3}{9} \right)}\implies \cfrac{27-27}{3-3}\implies \stackrel{unde fined}{\cfrac{0}{0}}$

When evaluating (3.25 times 10 Superscript 5 Baseline) (1.82 times 10 Superscript 3 Baseline), what will be the exponent of 10 i

boyakko [2]

Answer:

The exponent of 10 in the product is 8.

Step-by-step explanation:

The expression is as follows:

$(3.25\times 10^{5})\cdot (1.82\times 10^{3})$

Exponent rule:

$a^{m}\times a^{n}=a^{m+n}$

Simplify the expression as follows:

$(3.25\times 10^{5})\cdot (1.82\times 10^{3})=3.25\times 10^{5}\times 1.82\times 10^{3}$

$=(3.25\times 1.82)\times (10^{5}\times 10^{3})\\\\=5.915\times 10^{5+3}\\\\=5.915\times 10^{8}$

Thus, the exponent of 10 in the product is 8.
