Answer:

2% as a decimal would be 0.02

Step-by-step explanation:

Where I learned, we do DR. Pepper. We use the DR. 2% is in the ones place. The decimal point goes from the right of R to the left of D. 2% would then be 0.02.

computing definite integral by appealing to geometric formulas Graph the following definite integral then find the exact area of

sergiy2304 [10]

First integral

Since $f(x)=3x+1$ is a linear function, its graph is a line. This means that you can decompose the area under its graph as the sum of a right triangle and a rectangle, as shown in the attached image.

All the dimensions are fairly easy to deduce: we have

$AC = 2,\ CB=6$

So, the area of the triangle is

$A_t = \dfrac{2\times 6}{2}=6$

For the rectangle, we have

$A_r = AC\times CE = 2\times 4=8$

So, the total area is $6+8=14$

Second integral

We have

$y = \sqrt{1-x^2} \implies y^2=1-x^2 \implies x^2+y^2=1$

So, this function is the upper half of the unit circle (the two halves are the functions $y=\pm\sqrt{1-x^2}$ )

Since the area of the unit circle is $\pi$ , the value of the integral is $\frac{\pi}{2}$

Third integral

It follows the exact same logic as the first one, you only have to adjust the numbers.

A team in science class placed a chalk mark on the side of a wheel and rolled the wheel in a straight line until the chalk mark

natita [175]

The amount of distance the wheel rolled is the circumference of that wheel. So we know the circumferenece of the wheel is 35cm; this is important because the formula for finding circumference is $2 \pi r = C$ . We can solve this for radius.

$2 \pi r = 35$

Divide by 2.
$\pi r = 17.5$

Divide by $\pi$
$r = 5.57$

So we now know the radius of the wheel is 5.57. We can then use this knowledge to find the area of the wheel. The formula for area is $\pi r^2 = A$

$\pi 5.57^2 = A$

Square 5.57.
$\pi 31.02 = A$

Multiply by $\pi$
$97.47 = A$

This means the answer is the last one in the list given.

Convert y - 3 = 1/3 (x - 6) to standard form.

MAXImum [283]

Y - 3 = 1/3(x - 6)
y - 3 = 1/3 x -2
y = 1/3 x - 2 + 3
y = 1/3 x - 1

Answer ⇒ y = 1/3 x - 1
