School pennants cost $18 each. Ms.Lee says she will pay $146 for 7 pennants. Is her answer reasonable?

crimeas [40]

Well, all we have to do to figure out if Ms. Lee’s offer is reasonable is multiply the unit price ($18) by 7

18 x 7 = 126

Since she offered $146, she could actually purchase 8 pennants for $144

Therefore, her answer wouldn’t be reasonable

Hope this helps you

if I have to add 97 oz of algaecide to 10,000 gallons of water how much should I add if I only have 200 gallons of water

juin [17]

Answer:

1.94 oz

Step-by-step explanation:

x/97 = 200/10000

97*200 = 10,000x

19400 = 10,000x

1.94 oz

You can also do it this way:

200/10000 = 0.02

0.02 * 97 = 1.94

If my answer is incorrect, pls correct me!

If you like my answer and explanation, mark me as brainliest!

The formula κ(x)= f′′(x) 1+f′(x)23/2 expresses the curvature of a twice-differentiable plane curve as a function of x. Use thi

Katyanochek1 [597]

Answer:

K(x) = $\frac{-10}{[1 + (-10x)^2]^{\frac{3}{2} } }$ ( curvature function)

Step-by-step explanation:

considering the Given function

F(x) = $-5x^2$

first Determine the value of F'(x)

F'(x) = $\frac{d(-5x^2)}{dy}$

F'(x) = -10x

next we Determine the value of F"(x)

F"(x) = $\frac{d(-10x)}{dy}$

F" (x) = -10

To find the curvature function we have to insert the values above into the given formula

K(x) $= \frac{|f"(x)|}{[1 +( f'(x)^2)]^{\frac{3}{2} } }$

K(x) = $\frac{-10}{[1 + (-10x)^2]^{\frac{3}{2} } }$ ( curvature function)

Write the equation in slope-intercept form, for the line that would coincide with (be in line with) line segment AB.

Llana [10]

Answer:

$y=2$

Step-by-step explanation:

We are finding the equation of the line that coincide with line segment AB.

So, we can find the equation by using points A and B.

$A\rightarrow(-3,2)\\B\rightarrow)(1,2)$

Slope of line (m) = $\frac{y_2-y_1}{x_2-x_1} = \frac{2-2}{1-(-3)} = 0$

Since slope = 0, therefore the line is parallel to x-axis.

The equation of line is given by $y=mx+b$

where $m$ is slope and $b$ is y-intercept.

So equation of line AB:

where $m=0$ and $b=2$

$y=(0)x+2$

$y=0+2$

$y=2$
