PLS HELP ME ON THIS QUESTION I WILL MARK YOU AS BRAINLIEST IF YOU KNOW THE ANSWER!! Determine The Value

Answers

Answer 1

Answer:

6

Step-by-step explanation:

5

Answer 2

Answer:

k = 10

Step-by-step explanation:

Given 2 secants from an external point to the circle, then

The product of the external part and the whole of one secant is equal to the product of the external part and the whole of the other secant, that is

2x(2x + kx) = 3x(3x + 5x)

4x² + 2kx² = 3x × 8x = 24x² ( subtract 4x² from both sides )

2kx² = 20x² ( divide both sides by 2x² )

k = 10

Your answer will be either A or B, but since the sign is less than it should be A. Anytime the greater or less than sign is pointing towards less than then you’ll shade all of the bottom portion of the graph. If it’s greater than then you’d shade above. Hope this helped!

According to the rational root theorem what are all potential rational roots of F(x)=9x^4-2x^2-3x+4

Answers

Answer:

The answer is

[tex]( + - )(1)( \frac{1}{3} )( \frac{1}{9} )(2)( \frac{2}{3} )( \frac{2}{9} )(4)( \frac{4}{3} )( \frac{4}{9} )[/tex]

Explanation:

Rational root theorem, also called rational root test, in algebra, theorem that for a polynomial equation in one variable with integer coefficients to have a solution (root) that is a rational number, the leading coefficient (the coefficient of the highest power) must be divisible by the denominator of the fraction and

and the constant term (the one without a variable) must be divisible by the numerator.

In f(x), the ratio is

[tex] \frac{4}{9} [/tex]

because 4 is the constant and 9 is leading term

So our factors are

[tex] \frac{4}{9} = \frac{ + - (1)(2)(4)}{ + - (1)(3)(9)} [/tex]

Answer:

$504

$600* .8 = $480

$480 * 1.05 = $504

Step-by-step explanation:

Answer:

Step-by-step explanation:

Abel:

Cost price = $ 600

Loss = 20%

Selling price = [tex]\frac{100-loss}{100}*Cost \ price[/tex]

                     [tex]= \frac{(100-20)}{100}*600\\\\=\frac{80}{100}*600[/tex]

                     = 80 * 6 = $ 480

Cost price for Bob = Selling price of Abel = $ 480

Bob's cost Price = $480

Selling price = [tex]\frac{100+Profit}{100}*CP\\\\[/tex]

                     [tex]= \frac{100+5}{100}*480\\=\frac{105}{100}*480[/tex]

                      = $ 504

Amount paid by Charles =$ 504

Please help me with this

Answers

Answer:

108

Step-by-step explanation:

Surface area = total area of net

The net is made up of 2 unique shapes

A square with a side length of 6

The area of a square can be calculated by squaring the side length

6^2 = 36

The area of the square = 36

The net is also made up of 4 triangles

The triangles have a base length of 6 and a height of 6

The area of a triangle can be calculated by using the formula A = (bh) / 2

Where b = base length and h = height

If the triangles have a base length of 6 then b = 6 and if they have a height of 6 then h = 6

So A = 6*6/2

6 * 6 = 32

32/2 = 18

We then multiply that by 4 to get the area of all four triangles

18 * 4 = 72

Finally we add the areas together

72 + 36 = 108

The surface area is 108

What is the slope-intercept form is?

Answers

Slope intercept form is y = -3/4x - 3

Can someone help me with this math homework please!

Answers

Answer:

It's 2, 1, and y = 2x + 1.

Step-by-step explanation:

You can see the rise is 2 and the run is 1, making the slope = 2, and the y-intercept is 1 because that is where it crosses the y axis. Once you have the slope and y intercept, you can put it in a function, with the form being y=2x+1, the slope being the number before the x and the y-int value being after the x.

Answer:

1.  2

2. 1

3. y = 2x+1

Step-by-step explanation:

Calculate the mean, median, and mode of the following set of data. Round to the nearest tenth. 12,7,12,9,2,15,6,6,6,1,11

Answers

Answer:

Mean: 7.9
Median: 7
Mode: 6

Step-by-step explanation:

Sort the date set!

1, 2, 6, 6, 6, 7, 9, 11, 12, 12, 15

Then start by finding the mean of the data set!

Mean: the sum of all numbers divided by the amount of numbers

Mean = 1 + 2 + 6 + 6 + 6 + 7 + 9 + 11 + 12 + 12 + 15 = 87 divided by 11 = 7.9

Median: middle number in the data set

Data set: 1, 2, 6, 6, 6, 7, 9, 11, 12, 12, 15

Median = 7 because it is in the middle

Mode: the number that is being used the most

Data set: 1, 2, 6, 6, 6, 7, 9, 11, 12, 12, 15

Mode = 6 because it is used 3 times

Find sin X.
a. sin X= 4/5
b. sin X= 3/4
c. sin X= 3/5
d. sin X= 5/4

Answers

Answer:

sin X = 4/5

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

sin X = opp side/ hypotenuse

sin X = 36/45

        = 4/5

Let's find the value of sin X,

→ opp/hyp

→ 36/45

→ 4/5

The required answer will be,

→ a. sin X= 4/5

So, option (a) is the answer.

Answers

Answer:

A

Step-by-step explanation:

I did not look up the actual numbers, but it can only be A.

of course, the whole aim is larger than the nucleus, which is why C is impossible with its negative exponent (which would make the whole aim smaller than the nucleus).

and B. can't be true, because it is so big 10¹⁴ times bigger than a 10-¹⁵ atom ? this would make the whole atom the size of about 10-¹ meters. so, 10 cm. a single hydrogen atom would be bigger than a tennis ball. which it isn't.

so, that only leaves A.

Answers

Answer:

C. Scarlett shaded the multiples instead of the factors of 15

Step-by-step explanation:

Scarlett tried to shade all the factors of 15 on the hundred chart 15,45,75,30,60,90 What mistake did she make

She shaded 15,45,75,30,60,90 on the chart

Factors of 15 are 1, 3, 5 and 15

15, 45, 75, 30, 60, 90 are multiples of 15

That is,

15 × 1 = 15

15 × 3 = 45

15 × 5 = 75

15 × 2 = 30

15 × 4 = 60

15 × 6 = 90

Therefore Scarlett's mistake is:

C. Scarlett shaded the multiples instead of the factors of 15

5 – 2x = 3 what is x?

Answers

Answer: x=1

Step-by-step explanation:

To solve for x, we want to isoate the variable.

5-2x=3         [subtract both sides by 5]

-2x=-2          [divide both sides by -2]

x=1

Now, we know that x=1.

Answer:

X = 1

Step-by-step explanation:

Add 2x to both sides of the equation

5-2x+2x=3+2x

5+0=3+2x

Subtract 3 from both sides of the equation

5-3=3-3+2x

2=0+2x

2x=2

x=2/2

X = 1

What are ways using coordinate geometry, that I could determine that this is a trapezoid?

Answers

One method to see it's a trapezoid is to find the slope of lines BC and AD.

The slope formula is

m = (y2-y1)/(x2-x1)

You should find that BC and AD both have the same slope (of -1), so that means the lines are parallel. That proves we have a trapezoid.

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

To prove this trapezoid is isosceles, you can use the distance formula

[tex]d = \sqrt{ \left(x_1-x_2\right)^2 + \left(y_1-y_2\right)^2}[/tex]

to find the lengths of AB and CD (the two non-parallel sides). You should find that AB = CD.

Because AB and CD are horizontal and vertical respectively, this means you can simply count out the spaces to find that AB and CD are 3 units each. For any other rotated version of this trapezoid, use the distance formula instead.
