Answer:

$5.61

Step-by-step explanation:

Since David only has $9.39 but he needs $15.00 for his purchase. So, you would subtract the $9.39 from the $15.00 to see how much more money David needs to make this purchase.

15.00 - 9.39

When you carry out this problem, it equals $5.61.

Therefore, David needs $5.61 to be able to complete his purchase

2) Calculate the surface<br> area of the cylinder:<br> 5 cm
AVprozaik [17]

Answer:

28π cm²

Step-by-step explanation:

The surface of a cylinder is given by the formula:

  • 2πrh + 2πr²

where r is the radius of the base, and h is the height.

Using the image, we can find that the radius of the cylinder would be 2 cm, and the height would be 5 cm.

Now, to find the surface area of the cylinder, we would have to plug in 2 for r (the radius of the base) and 5 for h (the height of the cylinder) into the formula for the surface area of a cylinder.

Now we plug in 2 for r and 5 for h for the equation for the surface area of a cylinder:

2π(2)(5) + 2π(2)² = 20π + 2π(4) = 20π + 8π = 28π

Remember, the radius and the height are given to us in cm, and w are solving for surface area, so the answer should be in cm² (square centimeters).

The surface area of the cylinder would be 28π cm².

28π cm² would be an exact answer. For the approximate answer, plug in 3.14 (most math classes use 3.14 to approximate π) for π.

I hope you find this helpful. :)

Write the point-slope form of the equation of the line that passes through the points (-3, 5) and (-1, 4). Please answer quickly
Oksanka [162]
The point-slope form of the equation of a line is

y - y_1 = m(x - x_1)

where

(x_1, y_1)

is a point on the line, and

m

is the slope of the line.

We can use either one of the two given points as the point on the line.
We also need to find the slope. We can use the coordinates of the two given points to find the slope of the line.

The slope of the line that passes through points

(x_1, y_1) and (x_2, y_2)

is

m = \dfrac{y_2 - y_1}{x_2 - x_1}

Let's find the slope using (-3, 5) as point 1 and (-1, 4) as point 2.

m = \dfrac{4 - 5}{-1 - (-3)} = \dfrac{-1}{-1 + 3} = \dfrac{-1}{2} = -\dfrac{1}{2}

Now we use the point-slope formula with point 1 and the slope we found just above.

y - y_1 = m(x - x_1)

y - 5 = -\dfrac{1}{2}(x - (-3))
