Answer:

x = 25

Step-by-step explanation:

Given:

Since ∠A is equivalent to ∠B...

[tex]\implies (7x - 8)= (6x + 17)[/tex]

Open the parenthesis:

[tex]\implies 7x - 8= 6x + 17[/tex]

Add 8 both sides:

[tex]\implies 7x - 8 + 8= 6x + 17 + 8[/tex]

Simplify both sides:

[tex]\implies 7x = 6x + 25[/tex]

Subtract 6x both sides:

[tex]\implies 7x - 6x = 6x - 6x + 25[/tex]

Simplify both sides:

[tex]\implies x = 25[/tex]

Answer:

 x = 25

Step-by-step explanation:

Putting Both angels together:

Since,

m∠A = (7x - 8)°

m∠B = (6x + 17)°

Then,

(7x-8) = (6x+17)

Solving for x:

7x - 8 = 6x + 17

    + 8           +8

--------------------------

7x = 6x + 25

-6x   -6x    

-------------------

x = 25

Hence Answer is 25

Answer:

y = 8

Step-by-step explanation:

Hi there!

We are given the equation 5y + 2 = 42

And we want to solve it for y

To do that, we need to isolate the variable y on one side - we don't want any numbers on the same side as y.

So we need to first get rid of any numbers on the same side as y; we can subtract 2 from both sides to remove it from the left side.

5y + 2 = 42

     -2      -2

_______________

5y = 40

Now, we have variables on one side and numbers on another, but we're not done yet, as we want the value of just y, not 5y (that's 5 * y)

So to find the value of just y, divide both sides by 5

5y = 40

÷5    ÷5
________

y = 8

Hope this helps!

Answer:

The correct option isn't shown on the image.  I have attached a DESMOS graph with the option listed, and added an approximate equation that comes close to the actual line.  This should aid in understanding the equations and lines.

Step-by-step explanation:

See attached image.

The one option is noted as the first equation.  I added two points from the line provided: (0,-2.5) and (3.5,0) and then approximated an equation that comes closer.  I simply chose 3x-4y=>10, and it comes close to the actual line that goes through the two given points.

To do this properly, find the equation, y=mx+b, of the given line using the two points selected:

Slope, m is rise/run:

Rise = 2.5

Run = 3.5

Slope = 2.5/3.5

y-intercept, b, is -2.5

The equation of the given line is y = (2.5/3.5)x - 2.5

We can rewrite this in the form the answer options are given, or rearrange the answer options to standard form in order to make the comparison.  

Hopefully this will help guide to the correct solution.

Answer:

Step-by-step explanation:

A population is a set of similar items or events which is of interest for some question or experiment.

Answer:

I guess 21

Step-by-step explanation:

Because if you find the other side by trigonometric theorem-

[tex]x^2 = c^2 - a^2\\x^2 = 12^2 -8^2\\x^2= 144 - 64\\x^2=80\\\sqrt{x} =\sqrt{80}\\ x=8.94[/tex]

which is almost 9

9 is a possible value

they ask you to find the value which doesn't fit in the triangle

so the answer is 21 which doesn't make any sence

Hopefully, the answer would be work

Answer:

f(x)=8,000(0.08)

Step-by-step explanation:

I am not 100% sertin but 8% = 0.08 so to find the percentage you would just multiple that by the given 8,000.

Answer:

see explanation

Step-by-step explanation:

(1)

f(x) = g(x) , that is

- x² + 3x - 2 = - x + 1 ( add x to both sides )

- x² + 4x - 2 = 1 ( subtract 1 from both sides )

- x² + 4x - 3 = 0 ( multiply through by - 1 )

x² - 4x + 3 = 0 ← in standard form

(x - 1)(x - 3) = 0 ← in factored form

equate each factor to zero and solve for x

x - 1 = 0 ⇒ x = 1

x - 3 = 0 ⇒ x = 3

(2)

let x and y be the 2 numbers : x > y , then

x + y = 217 → (1)

x - y = 85 → (2)

add the 2 equations term by term to eliminate y

2x + 0 = 302

2x = 302 ( divide both sides by 2 )

x = 151

substitute x = 151 into (1)

151 + y = 217 ( subtract 151 from both sides )

y = 66

the 2 numbers are 66, 151

Answer:

Step-by-step explanation:

So here this question is of concept linear equations. As in linear equations we assumes the unknown number as an variable after that an equation would be formed which we would solve and get the answer. Here also we would be doing same.!!

Let us assume the first consecutive positive integer as m. Therefore, second and third consecutive number would be (m + 1) and (m + 2) respectively.

Refer to the attachment now.

Probability of an event is the measure of its chance of occurrence. The correct probabilities are:

Suppose that the sample space is S. Out of which there are two events, A and B, subsets of S.

Then, we can interpret P(A|B) as the probability of that part of A which is in B, with the new sample space as B. (assuming probabililty of B isn't 0).

Symbolically, we write it as:

[tex]P(A|B) = \dfrac{P(A \cap B)}{P(B)}[/tex]

For three sets, A, B and C:

[tex]n(A \cup B \cup C) = n(A) + P(B) + P(C) - n(A\cap B) - n(A \cap C) - n(B \cap C) + n(A \cap B \cap C)[/tex]

The problem is incomplete. The corresponding venn diagram is attached below.

We can symbolize the venn diagram as:

[tex]n(A) = 12+8+6+5 =31\\n(B) = 11+8+5+3 = 27\\n(C) = 4+8+6+3 = 21\\n(A \cap B) = 5+8=13\\n(B\cap C) = 3+8=11\\n(A \cap C) = 6+8=14\\n(A \cap B \cap C) = 8[/tex]

S = sample space = collection of all unique elements.

S is union of A, B and C.

[tex]n(S) = n(A \cup B\cup C) = 31 + 27 + 21 -13-11-14+8 = 49[/tex]

Checking all the options for their correctness:

We have:

[tex]P(A|C) = P(A\cap C)/P(C) = \dfrac{n(A\cap C)/n(S)}{n(C)/n(S)} = \dfrac{n(A \cap C)}{n(C)} = \dfrac{14}{21} =\dfrac{2}{3}[/tex]

Thus, its correct.

[tex]P(C|B) = P(C\cap B)/P(B) = \dfrac{n(C\cap B)/n(S)}{n(B)/n(S)} = \dfrac{n(C \cap B)}{n(B)} = \dfrac{11}{27} \neq \dfrac{8}{27}[/tex]

Thus, this option is incorrect.

Thus, this option is incorrect.

[tex]P(C) = \dfrac{n(C)}{n(S)}= \dfrac{21}{49} =\dfrac{3}{7}[/tex]

Thus, its correct.

[tex]P(B|A) = P(B\cap A)/P(A) = \dfrac{n(B\cap A)/n(S)}{n(A)/n(S)} = \dfrac{n(B\cap A)}{n(A)} = \dfrac{13}{31} \neq \dfrac{13}{27}[/tex]

Thus, this option is incorrect.

Thus, the correct probabilities are:

Step-by-step explanation:

the arrow is showing exactly in-between the 10 and 20 which means it is 15

Explanation:

Use the intersecting chords theorem to find x

JN*NK = MN*NL

(3x+6)*16 = (7x-11)*14

48x+96 = 98x-154

96+154 = 98x-48x

250 = 50x

50x = 250

x = 250/50

x = 5

This means,

JN = 3x+6 = 3(5)+6 = 21

JK = JN+NK = 21+16 = 37

The fourth function, f(x) = (x+2)^2-1 has an axis of symmetry of x = -2.

All of these functions start from the same function, f(x) = x^2, which has an axis of symmetry of x = 0.

A quadratic function is the second-order degree algebraic expression in a variable. the standard form of this expression is  ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.

The first function has been shifted 1 unit to the right and 2 units up, which have an axis of symmetry at x = 1.

The second function has been shifted 1 unit to the left and 2 units down, which have an axis of symmetry at x = -1.

The third function has been shifted 2 units to the right and 1 unit down, which have an axis of symmetry at x = 2.

The fourth function has been shifted 2 units to the left and 1 unit down, which have an axis of symmetry at x = -2.

As you can see, the last function has been shifted 2 units to the left, which has an axis of symmetry at x = -2.

Thus, The fourth function, f(x) = (x+2)^2-1 has an axis of symmetry of x = -2.

Area of a triangle: [tex]\frac{1}{2}bh[/tex]

Area of the left triangle:

[tex]\frac{1}{2}(x+4)(6)[/tex]

The 6 multiplied by the 1/2 equals 3, so:

[tex]A = 3(x+4)[/tex]

Area of the right triangle:

[tex]\frac{1}{2}(x-2)(6)\\[/tex]

Again, the 6 multiplied by the 1/2 equals 3, so:

[tex]A= 3(x-2)[/tex]

Adding the two areas together equals:

[tex]3(x+4) + 3(x-2)[/tex]

We can factor out the 3 from both, giving us the final answer:

[tex]A = 3((x-4)+(x-2))[/tex]

The length of this pendulum that makes one full swing is 3.93 meters.

Mathematically, the time taken by this pendulum is given by this formula:

[tex]\rm T=2\pi \sqrt{\dfrac{L}{32}}[/tex]

Making L the subject of the formula, we have:

[tex]\rm T=2\pi \sqrt{\dfrac{L}{32}}\\\\32T^2=4\pi ^2L\\\\L=\dfrac{32T^2}{4\pi ^2}\\\\[/tex]

Substitute all the values in the formula

[tex]\rm L=\dfrac{32T^2}{4\pi ^2}\\\\ L = \dfrac{32 \times 2.2^2}{4 \times 3.14 ^2\\}\\\\ L =\dfrac{154.88}{39.43}\\\\L=3.93 \ m[/tex]

Hence, the length of this pendulum that makes one full swing is 3.93 meters.
