A pyramid has a regular hexagonal base with the side lengths of 4 and a slant height of 6. Find the total area of the pyramid..

butalik [34]

For get the length of apothem write sin60 = a/4 so sqrt3 /2 = a/4 so a = 4sqrt3 /2

a = 2sqrt3

so area of base = 6(4*2sqrt3)/2 = 6*4sqrt3 = 24sqrt3 unit squared

the lateral area = 4*4*6/2 = 4*2*6 = 48 unit squared

total area = 24sqrt3 +48 = 24(sqrt3 +2) unit squared

hope this will help you

The table shows the battery life of four different mobile phones:

Pie

Answer:

A 20

Step-by-step explanation:

Given

Phone Battery Life (hours)

A 20

B 25

C 10

D 18

8.45% of the battery life of each mobile phone is used in a day by a typical user

Calculating Hours of battery life in a day for each mobile

A 20

Battery life for A = $\frac{8.45}{100}\times 20 = 1.69$ hours

B 25

Battery life for B = $\frac{8.45}{100}\times 25 = 2.11$ hours

C 10

Battery life for C = $\frac{8.45}{100}\times 10 = 0.845$ hours

D 18

Battery life for D = $\frac{8.45}{100}\times 18 = 1.52$ hours

Therefor Mobile phone A 20 uses a total of 1.69 hours of battery life in a day

Write f(x) = 2x2 – 44x 185 in vertex form. To write f(x) = 2x2 – 44x 185, factor out from the first two terms. Next, form a perf

Tasya [4]

The quadratic function f(x) = 2x² – 44x + 185 is written in vertex form is f(x) = 2(x – 11)² – 57.

<h3>What is a quadratic equation?</h3>

It is a polynomial that is equal to zero. Polynomial of variable power 2, 1, and 0 terms are there. Any equation having one term in which the power of the variable is a maximum of 2 then it is called a quadratic equation.

The quadrattic equation is f(x) = 2x² – 44x + 185.

Take common 2 from the equation, we have

$f(x) = 2(x^2 - 22x )+ 185$

Add and subtract 121, we have

$f(x) = 2(x^2 - 22x +121 - 121 )+ 185\\\\f(x) = 2[(x^2 - 11)^2-121]+ 185\\\\f(x) = 2(x-11)^2 - 242 + 185\\\\f (x ) = 2(x-11)^2 -57$

And we know that the standard equation

f(x) = a(x - h)² + k

On comparing, we have

The vertex (h, k) is (11, -57).

More about the quadratic equation link is given below.

Can anyone help me plzzzzz /deltamath

irakobra [83]

ANSWER: square root of 10

Rule: Pythagorean Theorem (a^2 + b^2 = c^2; side^2 + second side^2 = hypotenuse^2)

(substitute the missing side w/ a variable)
x^2 + 7^2 = (sqrt. 59)^2
x^2 + 49 = 59
x^2 = 10
x = sqrt. 10

Can someone explain to me how integers work?

ollegr [7]

What are Integers?

The integers (from the Latin integer, which means with untouched integrity, whole, entire) are the set of numbers consisting of the natural numbers including 0 (0, 1, 2, 3, ...) and their negatives (0, −1, −2, −3, ...). They are numbers that can be written without a fractional or decimal component, and fall within the set {... −2, −1, 0, 1, 2, ...}. For example, 65, 7, and −756 are integers; 1.6 and 1½ are not integers. In other terms, integers are the numbers one can count with items such as apples or fingers, and their negatives, including 0.
