Answer:

The area of the sector is 21.39 cm^2

Step-by-step explanation:

Mathematically, to calculate the area of a sector, the formula to use is;

A = Theta/360 * pi * r^2

where Theta is the angle subtended at the center of the circle = 50 degrees

r is the radius of the circle = 7cm

pi = 22/7

Substituting these values into the area of sector equation, we have;

A = 50/360 * 22/7 * 7 * 7 = (5 * 22*7 )/36 = 21.39 cm^2

Answer:

The 18th term of the sequence is -117.

Step-by-step explanation:

The given sequence is 2,-5,-12,-19

From this AP,

First term, a = 2

Common difference, d = -5-2 = -7

It is required to find the 18th term of the sequence. The nth term of an AP is given by :

[tex]a_n=a+(n-a)d\\\\a_{18}=a+17d\\\\a_{18}=2+17\times (-7)\\\\a_{18}=-117[/tex]

So, the 18th term of the sequence is -117.

C)you must be no older than 13 to play the game.

Step-by-step explanation:

≤this means equal to or less than which in this case is 13

The situation represented by the inequality g ≤ 13 will be option C. You must be no older than 13 to play the game.

When two expressions are connected by a sign like "not equal to," "greater than," or "less than," it is said to be inequitable. The inequality shows the greater than and less than relationship between variables and the numbers.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that the inequality is g ≤ 13.

The inequality can be represented by the situation you must be no older than 13 to play a game.

Answer:

87.6m²

Step-by-step explanation:

From the above question, we are given the following information

The dimensions of the base were 3 m by 5 m:

Length = 3m

Width = 5m

The pyramid was 3.6 m high

Height = 3.6m

To calculate the amount of ice needed for this sculpture, we would have to find the Surface Area of the Rectangular Prism

This is calculated as:

Surface Area =2(wl+hl+hw)

= 2(3 × 5 + 3.6 × 3 + 3.6 × 5)

= 2(15 + 10.8 + 18)

= 2(43.8)

= 87.6m²

The amount of ice needed for this sculpture is 87.6m²

Answer:

Option (A)

Step-by-step explanation:

Parent function (in red) graph is represented by,

f(x) = x²

If this function is translated by 'a' units to the right, rule to be followed,

f(x) → f(x - a)

If the parent function is shifted by 4 units to the right (blue graph), the new function will be,

g(x) = f(x - 4)

g(x) = (x - 4)²

Therefore, Option (A) will be the correct option.

The point-slope form of an equation of the line through the points (-7, 7) and (4,1):

(y - 7) = m(x + 7)

or

(y - 1) = m(x - 4)

with

m = (1 - 7)/(4+7) = -6/11

Answer:

y=-6/11 x +35/11

Step-by-step explanation:

(-7, 7) and (4,1)

m=y2-y1/x2-x1

m=1-7/4-(-7)

m=-6/11

Before the price reduction, the cost was 120 dollar.

Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

We are given that shop advertises 25% off its prices in a sale a dress is 90% .

28z+124=180

28z=56

z=2

26*2=52

Answer:

TV

Step-by-step explanation:

The sum of the angles of a triangle are 180

z+59 + z+65 + 26z = 180

Combine like terms

28z + 124 = 180

Subtract 124

28z = 180-125

28z =56

Divide by 28

28z/28 = 56/28

z=2

The smallest side is opposite the smallest angle

26*2 = 52  

<u is  the smallest angle so TV is the smallest side

Explanation:

The weird or fancy looking E symbol is the greek uppercase letter sigma. It is effectively the english version of S to represent summation. So we add up all the [tex](x-\overline{x})^2[/tex] terms to get this. Luckily this has already been done for us in the table where they wrote "sum = 34", so [tex]\sum(x-\overline{x})^2 = 34[/tex]

From here, we substitute this into the formula, along with n = 5 since there are 5 items in the original list

So,

[tex]s = \sqrt{\frac{1}{n-1}\sum(x-\overline{x})^2} \\\\s = \sqrt{\frac{1}{5-1}*34} \\\\s = \sqrt{\frac{1}{4}*34} \\\\s = \sqrt{0.25*34} \\\\s = \sqrt{8.5} \\\\s \approx 2.91547594742266 \\\\s \approx 2.9 \\\\[/tex]

This computes the sample standard deviation. To get the population standard deviation, you'd basically change the "n-1" to simply "n", and the rest of the formula is identical.

Answer:

all positive real numbers and 0

Step-by-step explanation:

The function has a square root in the x value, so this function can't have negative values, because a negative value of x would give a complex number for f(x), and positive values of x gives positive values of f(x).

The function f(x) can be zero, if the value of x is zero:

[tex]f(0) = \sqrt{0} /2 = 0/2 = 0[/tex]

So the function f(x) can only have positive values and the value 0.

Correct option: "all positive real numbers and 0"

Answer:

A.) 2000N

B.) 0

C.) 1414.2 N

Step-by-step explanation:

Given that the force on the rope = 1000N

A.) If the two students pull in the same direction, the resultant force will be addition of the two forces. That is

1000 + 1000 = 2000 N

B.) If the two students pull in the opposite direction, the resultant force will be sum of the two forces equal to zero. That is,

F1 + F2 = 0

F1 = positive 1000N

F2 = negative 1000N

Therefore, 1000 - 1000 = 0

The resultant force of the two forces is zero.

C.) If the two forces are at right angles, south and east to each other, the resultant force R will be achieved by using pythagorean theorem.

R = sqrt( 1000^2 + 1000^2 )

R = sqrt( 2000000 )

R = 1414.2 N

The resultant force of the two forces will be 1414.2N
