Find m(arc) IJ of circle H.

If:


m(arc) KJ=110 degrees


a=100,b=150,c=110,d=250

Answer:

A = 72 ft^2

Step-by-step explanation:

The area of a triangle is given by

A = 1/2 bh where b is the base and h is the height

A = 1/2 (9)*16

A = 72 ft^2

A = 72ft².

We have to use the area of a triangle equation A = (b*h)/2.

A triangle with a base b = 9ft and a height h = 16ft:

A = (9ft*16ft)/2 = 144ft²/2

A = 72ft²

51 is 33.3% of the number 153.15

The answer is option C.

Calculation:-

let the number be X,

       33.3% of X =51  (as per the question)

      (X*33.3)/100=51

      X=(51*100)/33.3

Answer:

√x+3=13

Step-by-step explanation:

The equation is √x+3=13 is radical because the unknown, x appears under a radical sign √.

To solve the equation, the unknown is left on one side of the equal sign and then both sides of the equal sign are raised to an equal power which would remove the radical sign.

For example,

√x+3=13

√x=13-3

√x=10

Removing radical.

(√x)²=10²

Answer:

r = ±1/√7

a₁ = 7 − √7

Step-by-step explanation:

The first term is a₁ and the second term is a₁ r.

a₁ + a₁ r = 48/7

The sum of an infinite geometric series is S = a₁ / (1 − r)

a₁ / (1 − r) = 7

Start by solving for a₁ in either equation.

a₁ = 7 (1 − r)

Substitute into the other equation:

7 (1 − r) + 7 (1 − r) r = 48/7

1 − r + (1 − r) r = 48/49

1 − r + r − r² = 48/49

1 − r² = 48/49

r² = 1/49

r = ±1/√7

When r is positive, the first term is:

a₁ = 7 (1 − r)

a₁ = 7 (1 − 1/√7)

a₁ = 7 − 7/√7

a₁ = 7 − √7

The value of the common ratio r is 1/√7 and the first term is 7 − √7 in the geometry progression.

The geometric series defined as a series represents the sum of the terms in a finite or infinite geometric sequence. The successive terms in this series share a common ratio.

The nth term of a geometric progression is expressed as

Tₙ = arⁿ⁻¹

The first term is a

So the second term is a r.

a + ar = 48/7

The sum of an infinite geometric series is :

S = a / (1 − r)

a / (1 − r) = 7

Solve for a,

a = 7 (1 − r)

Substitute value into the equation:

7 (1 − r) + 7 (1 − r) r = 48/7

1 − r + (1 − r) r = 48/49

1 − r + r − r² = 48/49

1 − r² = 48/49

r² = 1/49

r = ±1/√7

When r is positive, the first term will be:

a = 7 (1 − r)

a = 7 (1 − 1/√7)

a = 7 − 7/√7

a = 7 − √7

Thus, the value of the common ratio r is 1/√7 and the first term is 7 − √7 in the geometry progression.

Answer:

(- 5, 3 )

Step-by-step explanation:

Under a reflection in the y- axis

a point (x, y ) → (- x, y )

Hence

C(5, 3 ) → C'(- 5, 3 )

If ABC is reflected across the y-axis then the coordinates of c is (-5,3).

The coordinates refers to a point on the graph which are used to draw a line, a shape on the graph by plotting these points.

The coordinates of ABC presently are (1,3),(3,6),(5,3). If we just reflect ABC cross y-axis then on the second quadrant only the value of x changes, the value of y remains same. So we have to just put a negative sign in front of the value of x and it becomes -5 with the value of y=3.

Hence the coordinates of C is (-5,3).

When we factor out a expression, we seek the terms that are common and then take it away. This is the opposite of applying distributive. In this exercise, we need to factor the following expression:

[tex]-8a^2b-a^6b^4[/tex], so:

STEP 1: Applying exponent rules:

We know that:

[tex]a^{m+n}=a^mb^n[/tex]

So:

[tex]a^6b^4=a^2a^4bb^3[/tex]

Then, our expression remains:

[tex]-8a^2b-a^2a^4bb^3[/tex]

Step-by-step explanation:

The mean of a set of credit scores is u=690 and o=14.

mean = 690  and standard deviation SD = 14

We use z- score formula

z= 3.3 given

Plug in the values and find out x

Multiply 14 on both sides

46.2 = x- 690

Now add 690 on both sides

x= 736.2

Credit score is 720 that comes under 736.2

a. Arithmetic

b. [tex]a_{n} = a_{n-1} + 15[/tex]

c. [tex]a_{n} = 15n + 125[/tex]

Step-by-step explanation:

A sequence is arithmetic when the difference between one term and the next is a constant. On the other hand, a sequence is geometric when the next term is found by multiplying the previous by a constant.

In this case, the next term of the sequence can be found by adding $15. Therefore, the sequence is ARITHMETIC ✔️

The recursive formula will be the following: [tex]a_{n} = a_{n-1} + 15[/tex]

The explicit formula is the following: [tex]a_{n} = 15n + 125[/tex]

Step-by-step explanation:

The volume of a rectangular prism is L*H*B.

So the volume of the rectangular prism pictured here is 24*10*8

The volume of a triangle prism is 1/2 *H*L*B.

So the volume of the triangle prism pictured here is 1/2 *6*24*8

The volume of the whole figure is the sum of the volume of the rectangular prism and volume of the triangular prism which is in this case:

24*10*8 + 1/2 *6*24*8.

Answer is the first choice.

Graph with its function by translating the graph of y= √x is marked below.

A mathematical phrase, rule, or law that establishes the link between an independent variable and a dependent variable (the dependent variable). In mathematics, functions exist everywhere, and they are crucial for constructing physical links in the sciences. A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output.

Given,

y = √x

However, y= √x only displays the positive y values on a graph since you can never square a negative integer because no two identical numbers multiplied together are negative, among other reasons.

Making a function is standard. Since a function may only have one value for each input, we define x as the positive real integer such that (√x)2=x for every positive real √x.

Answer:

The correct option is 1.

Step-by-step explanation:

It is given that a system of inequalities can be used to determine the depth of a toy, in meters, in a pool depending on the time, in seconds, since it was dropped.

Let y be the depth of a toy and x is time, in seconds.

In the given graph a solid horizontal line passes through the point (0,-1) and shaded region is above the line. So, the inequality of red line is

[tex]y\geq -1[/tex]

The depth of a toy can be less than -1. It means the pool is 1 meter deep.

The blue line is a dashed line which passes through (0,0) and (2,-1).

So the slope of line is

[tex]m=\frac{y_2-y_1}{x_2-x_1}=\frac{-1-0}{2-0}=-\frac{1}{2}[/tex]

The equation of blue line is

[tex]y=mx+b[/tex]

where, m is slope and b is y-intercept.

[tex]y=-\frac{1}{2}x+0[/tex]

[tex]y=-\frac{1}{2}x[/tex]

The shaded region is below the line so the required inequality is

[tex]y< -\frac{1}{2}x[/tex]

it means the toy sinks at a rate of less than 1/2 meter per second.

Therefore the correct option is 1.

Step-by-step explanation:

So if 25 - x items are sold, and they each cost x, we can write an equation for the revenue to be

y = (25 - x)x

The vertex of this equation will represent the maximum revenue.  So we need to write this equation in vertex form so we can find the vertex.

Vertex from is

y = a(x - h)^2+ k,

where (h,k) represent the vertex.

the vertex form of this equation would be

[tex]y= -(x-\frac{25}{2} )^{2} +\frac{625}{4}[/tex]

And the vertex would be

[tex](\frac{25}{2} ,\frac{625}{4})[/tex]

This means the maximum revenue will occur when x = 25/2

The maximum revenue is at a price of $11.5 each for a certain lamp

The revenue is the total amount of money that can be made from selling a number of goods.

Revenue = price * total number of items

Since the price per item is x dollars and the total number of items is 25 - x, hence:

Revenue (R) = x * (25 - x) = 25x - x²

R = 25x - x²

The maximum revenue is at dR/dx = 0, hence:

dR/dx = 25 - 2x

25 - 2x = 0

2x = 25

x = $11.5

Hence, The maximum revenue is at a price of $11.5 each for a certain lamp.
