Answer:

Step-by-step explanation:

Step 1: find the derivative of y = x^2 + 12x - 7; it is 2x + 12.

This function represents the slope of the tangent line to the given curve at x.

Step 2: Substitute 4 for x in f '(x) = 2x + 12: f '(4) = 2(4) + 12 = 20

The slope of the tangent line to the graph of y = x^2 + 12x - 7 at x = 4 is 20.

nlexa [21]

$2\frac{1}{2}:1\frac{5}{8}=\frac{2\times2+1}{2}:\frac{1\times8+5}{8}=\frac{5}{2}:\frac{13}{8}=\frac{5}{\not2_1}\times\frac{\not8^4}{13}=\frac{5}{1}\times\frac{4}{13}=\frac{5\times4}{1\times13}=\frac{20}{13}=1\frac{7}{13}$

Laura shades 60 squares on her hundredths grid And Billy shades 50 squares on his hundredths grid. Write the decimal number that

Andre45 [30]

Answer:

$Laura = 0.60$

$Billy = 0.50$

0.60 > 0.50

Step-by-step explanation:

Given

$Laura = 60\ shades$

$Billy = 50\ shades$

Required

Represent using decimal number and compare

From the question, we understand that there are 100th grids;

So:

$Laura = \frac{60}{100}$

$Laura = 0.60$

$Billy = \frac{50}{100}$

$Billy = 0.50$

Comparing both decimals;

Since 0.60 is greater than 0.50, we have:

0.60 > 0.50
