4. What is the volume of the cone shown below?
Round to the nearest tenth.
5 ft.
d = 2 ft.

Answers

Answer:

5.2 cubic ft

Step-by-step explanation:

took the test

The volume of given cone is 5.23 cubic feet.

What is volume?

Volume is the measure of the capacity that an object holds.

Formula for the volume of cone

[tex]v = \frac{1}{3} \pi r^{2} h[/tex]

where,

v is the volume of cone

r is the radius of cone

h is the height of cone

According to the question we have

Diameter of cone is 2ft

⇒ radius of the cone = [tex]\frac{2}{2} = 1 feet[/tex]

Height of the cone is 5ft.

Therefore,

The volume of the cone  = [tex]\frac{1}{3}(1)\pi( 1)^{2} (5)[/tex]

Volume of cone = [tex]\frac{1}{3} (3.14)(1)(5) = 5.23 cubic feet[/tex]

Hence, hence the volume of given cone is 5.23 cubic feet.

Convert the equation 9x + y = 4 Into slope-intercept form. Make sure to simplify if possible.​

Answers

Answer:

x = -1/9y + 4/9

Step-by-step explanation:

9x+y=4

Step 1: Add -y to both sides.

9x+y+−y=4+−y

9x=−y+4

The required equation in slope intercept form is given by y = -9x + 4.

What is the slope of the line?

The slope of the line is a tangent angle made by line with horizontal. i.e. m = tanx where x in degrees

What is the intercept in the equation?

In the equation intercept is the value of the linear function where either of the variables is zero.

here,
The slope intercept of the line is given as,
y = mx + c,
Where m = slope of the line and c = y-intercept of the line,

Given equation of line 9x + y = 4
Rearrange the equation,
9x + y = 4
y = -9x + 4

Thus, the required equation in slope intercept form is given by y = -9x + 4.

Well 5% of £1200 would be £60 which would be equal to 1 year and then you multiply that by 5 to find 5 years which is 300 and then you add the £300 onto the starting amount so £1200 + £300 = £1500

Answer:

Step-by-step explanation:

Question (1)

x² + 10x + 12

= x² + 2(5x) + 5² - 5² + 12

= [x² + 2(5x) + 5²] - 5² + 12

= (x + 5)² - 25 + 12 [Since, a² + 2ab + b² = (a + b)²]

= (x + 5)² - 13

Question (2)

y² - 6y - 15

= y² - 2(3y) - 15

= y² - 2(3y) + 3² - 3² - 15

= [y² - 2(3y) + 3²] - 3² - 15 [Since, a² - 2ab + b² = (a - b)²]

= (y - 3)² - 3²- 15

= (y - 3)² - 9 - 15

= (y - 3)² - 24
