Find the surface area of the pyramid.

Answer:

Perimeter = 133.681 cm

or 52.63 inches.

Step-by-step explanation:

"So, the perimeter of a semicircle is 1/2 (πd) + d or πr + 2r, where r is the radius."

let's use,  πr + 2r

Diameter: 52

Radius: 26 (RAdius is half of the diameter)

πr + 2r (plug in)

pi x 26 + 2(26)

pi x 26 + 52

= 133.681 cm

or

= 52.63

Answer:

(the relation you wrote is not correct, there may be something missing, so I will simplify the initial expression)

Here we have the equation:

[tex]sin^4(x) + cos^4(x)[/tex]

We can rewrite this as:

[tex](sin^2(x))^2 + (cos^2(x))^2[/tex]

Now we can add and subtract cos^2(x)*sin^2(x) to get:

[tex](sin^2(x))^2 + (cos^2(x))^2 + 2*cos^2(x)*sin^2(x) - 2*cos^2(x)*sin^2(x)[/tex]

We can complete squares to get:

[tex](cos^2(x) + sin^2(x))^2 - 2*cos(x)^2*sin(x)^2[/tex]

and we know that:

cos^2(x) + sin^2(x) = 1

then:

[tex]1 - 2*sin(x)^2*cos(x)^2[/tex]

This is the closest expression to what you wrote.

We also know that:

sin(x)*cos(x) = (1/2)*sin(2*x)

If we replace that, we get:

[tex]1 - \frac{sin^2(2*x)}{2}[/tex]

Then the simplification is:

[tex]cos^4(x) + sin^4(x) = 1 - \frac{sin^2(2*x)}{2}[/tex]

Answer:

Step-by-step explanation:

V_C_C

for the vowel = 2/5

for the consonant = 3/5

for next three picks it should be 2/5 * 3/5 *3/5 = 0.144

Answer:

D

Step-by-step explanation:

Vowel is 2/5 or 40%

Consonant is 3/5 or 60%

VCC is .4 x .6 x .6 = .144

Answer:

the answer is 16.6 Pizzas

Step-by-step explanation:

16% of 40 is 6.4 that means she sold 6 full pizzas and 0.4 parts of one pizza

add that to 18 is 24.4 pizzas sold and 16.6 to go.

Answer:

4x^5 + x^3 + 2x^2 -3

Step-by-step explanation:

Standard form is ( put simply ) the order the numbers are from highest to lowest. So the standard form of the equation would be 4x^5 + x^3 + 2x^2 -3

Answer:

  The CPI increased 3.42% in Month 2.

Step-by-step explanation:

In a spreadsheet, the weighted sum is easily computed using the SUMPRODUCT( ) function. It multiplies the corresponding values of two arrays, then returns the sum of those products. If one of the values is a weight, then the result is a weighted sum.

Your CPI is computed as the weighted sum of the prices of the individual products. The percentage change is computed in the usual way:

  pct change = ((new value)/(old value) -1) × 100%

Of course, the spreadsheet can format a fraction as a percentage, so the computation of the change can stop after 1 is subtracted from the ratio.

Answer:

Step-by-step explanation:

The correct rule for y in terms of x is

y = 3x - 4

we can check even

here when x = 1

y = 3 * 1 - 4 = - 1

similarly

when x = 2

y = 3 * 2 - 4 = 2

and so on you can check.

hope it helps :)

Answer:

the rule is y=3x-4

Step-by-step explanation:

m=y2-y1/x2-x1

m=2--1/2-1

m= 3/1

m=3

general equation of a line,

y=mx+c

if y=3x+c

if x=1 y=-1

-1=3+c

-4=c

therefore y=3x-4

Answer:

Scientific notation is a way of writing very large and very small numbers.

A number in scientific notation has the form  

N

×

10

a

, where  

N

is a number between 1 and 10, and  

a

is a positive or negative integer.

To convert to scientific notation, you move the decimal point until the new form is a number between 1 and 10 (

N

) and then record the exponent (

a

) as the number of places the decimal point was moved.

If you move the decimal to the right, the exponent is negative.

Express  

0.000 000 03 g

in scientific notation.

Step 1. Move the decimal place to the right to create a new number between 1 and 10.

This gives  

N

=

3

.

Step 2. Count the number of times you moved the decimal.

You moved the decimal 8 places to the right.

That means the exponent  

a

=

-8

.

Step 3. Write the number in scientific notation.

0.000 000 03 g

=

3

Answer:

[tex]x = 6[/tex]

Step-by-step explanation:

These right triangles are similar due to the Angle Angle Similarity Theorem.

This means their side lengths are proportional

We need to find the corresponding sides of the inner triangle and full right triangle.

7 corresponds with 7 and 3.5

4 corresponds with x.

Set up proportion.

[tex] \frac{4}{7} = \frac{x}{7 + 3.5} [/tex]

[tex] \frac{4}{7} = \frac{x}{10.5} [/tex]

[tex]42 = 7x[/tex]

Answer:

Step-by-step explanation:

The base angles are congruent in an isosceles trapezoid.

  ∠1 = 49°

Same-side angles are supplementary in any trapezoid.

  ∠2 = ∠3 = 180° -49°

  ∠2 = ∠3 = 131°

Answer:

134.6

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula. This is X when Z has a p-value of 1-0.01 = 0.99. So it is X when Z = 2.325.

The level is L = 134.6

The Central Limit Theorem estabilishes that, for a random variable X, with mean  and standard deviation, large sample size can be approximated to a normal distribution with a mean and standard deviation

Answer:

295 square feet

Step-by-step explanation:

Break the figure up into 3 rectangles, and then find the area of each rectangle and add all areas together.

15*3=45

19*10=190

15*4=60

45+190+60=295

Answer:26 *15*4*5*3=23400

Step-by-step explanation: Area is measured in square units such as square inches, square feet or square meters. To find the area of a rectangle, multiply the length by the width. The formula is: A = L * W where A is the area, L is the length, W is the width, and * means multiply.
