Y=-4x²-3x+3
y-3=-4x²-3x
y-3=-4(x²+3/4)x)
y-3-4*(3/8)²=-4(x²+2(3/8)x+(3/8)²)
y- 3.5625 =-4(x+(0.375))²
y= -4(x+(0.375))² + 3.5625

vertex (-0.375, 3.5625)

The distance from Caleb's house to the school is 1.5 miles, and the distance from Ashley's house to the school is 3520 feet. Who

lapo4ka [179]

Hi there!

To solve this problem, first we need to convert everything into feet.

1.5 mi = 7920 ft

Since
7920 is greater than 3520,

Ashley lives closer to the school.

Hope this helps!

The lung capacity of the blue whale is 5100L. Convert this volume into gallons. Express your answer to two significant figures a

Vedmedyk [2.9K]

By definition, we have that the conversion of a US gallon to liters is given by:
1 liter = 3.78541 gallons
Therefore, we can apply the following rule of three:
1 liter ---------------------> 3.78541 gallons
5100 liters --------------> x
Clearing x we have:
$x = (5100) * (3.78541)

x = 19305.591$
two significant figures:
$x = 19000
$
Answer:
The lung capacity of the blue whale is:
$x = 19000 gallons$

Selina is playing a game that uses the spinner below.

MatroZZZ [7]

Answer:

A) 12.5%

B) 50%

C) 50%

Step-by-step explanation:

For A, 7 is one of the 8 possibilities (1/8). 1/8 of 100 is 12.5, so your chance of spinning a 7 is 12.5%

For B, even numbers are 4/8 or 1/2 of your options. 1/2 of 100 is 50, so your chance of spinning an even number is 50%

For C, there are 4 out of 8 numbers that are prime (2,3,5, & 7).

4/8 or 1/2 of 100 is 50, so your chance of spinning a prime number is 50%

hope this helps

Find the volume of the cylinder if the height is 3 mm and the diameter is 40 mm. Leave the answer in terms of it.

KiRa [710]

The Volume of cylinder is 3770 cubic millimeters

But, the correct option is not available in options given.

Step-by-step explanation:

Height of cylinder = 3mm

Diameter of cylinder = 40mm

Volume of cylinder = ?

The formula used to find Volume of cylinder is:

$Volume = \pi r^2h$

Putting values in the formula:

Since we need radius,

radius = diameter/2

radius = 40/2

radius = 20 mm

So,

$Volume = \pi r^2h\\Volume = 3.14*(20)^2*3\\Volume = 3.14*400*3\\Volume= 3769.91 or \,\,\,Volume\approx 3770\,\,cubic\,\,millimeters$

The Volume of cylinder is 3770 cubic millimeters

But, the correct option is not available in options given.
