Answer:

  (b)  25 cm²

Step-by-step explanation:

The ratio of areas is the square of the ratio of linear dimensions.

  ar(ΔABC)/ar(ΔDEF) = (AB/DE)² = (1/2)² = 1/4

Then ...

  ar(ΔABC) = (1/4)(100 cm²) = 25 cm² . . . . . multiply by ar(ΔDEF)

The area of ΔABC is 25 cm².

Find x and y so the quadrilateral is a parallelogram.

Answers

Answer:

We conclude that:

The value of x = 7The value of y = 4

Step-by-step explanation:

Given

The parallelogram PQRS

We know that the diagonals of a parallelogram bisect each other.

so

[tex]RT = TP[/tex]

Given

RT = xTP = 5x-28

so substituting RT = x, and TP = 5x-28

[tex]RT = TP[/tex]

[tex]x = 5x-28[/tex]

[tex]5x = x+28[/tex]

[tex]5x-x = 28[/tex]

[tex]4x = 28[/tex]

divide both sides by 4

[tex]4x/4 = 28/4[/tex]

[tex]x = 7[/tex]

Therefore, the value of x:

x = 7

Similarly,

[tex]QT = TS[/tex]

Given

QT = 5yTS = 2y+12

so substituting QT = 5y, and TS = 2y+12

[tex]QT = TS[/tex]

[tex]5y = 2y+12[/tex]

[tex]5y-2y = 12[/tex]

[tex]3y = 12[/tex]

divide both sides by 3

[tex]3y/3 = 12/3[/tex]

[tex]y = 4[/tex]

Therefore, the value of y:

y = 4

Therefore, we conclude that:

The value of x = 7The value of y = 4

Answers

Answer:

y - 12 = 3(x - 5)

Step-by-step explanation:

Going from (-2, -9) to (5, 12), x (the run) increases by 7 and y (the rise) increases by 21.  Thus, the slope of this line is m = rise / run = 21/7 = 3.

Using the point-slope formula y - k = m(x - h), we get:

y - 12 = 3(x - 5)

Answer:

  4)  6x

  5)  2x +3

Step-by-step explanation:

We can work both these problems at once by finding an applicable rule.

  [tex]\text{For $f(x)=ax^n$}\\\\\lim\limits_{h\to 0}\dfrac{f(x+h)-f(x)}{h}=\lim\limits_{h\to 0}\dfrac{a(x+h)^n-ax^n}{h}\\\\=\lim\limits_{h\to 0}\dfrac{ax^n+anx^{n-1}h+O(h^2)-ax^n}{h}=\boxed{anx^{n-1}}[/tex]

where O(h²) is the series of terms involving h² and higher powers. When divided by h, each term has h as a multiplier, so the series sums to zero when h approaches zero. Of course, if n < 2, there are no O(h²) terms in the expansion, so that can be ignored.

This can be referred to as the power rule.

Note that for the quadratic f(x) = ax^2 +bx +c, the limit of the sum is the sum of the limits, so this applies to the terms individually:

  lim[h→0](f(x+h)-f(x))/h = 2ax +b

__

4. The gradient of 3x^2 is 3(2)x^(2-1) = 6x.

5. The gradient of x^2 +3x +1 is 2x +3.

__

If you need to "show work" for these problems individually, use the appropriate values for 'a' and 'n' in the above derivation of the power rule.

Which choice is the solution set for the inequality below , sqrt of x > 11 , I had put x>121 n got it wrong not sure what I need to do

Answers

Answer: Option B, x ≥ 121

Step-by-step explanation:

We start with the inequality:

√x ≥ 11.

First, we can square each side of the inequality, to get:

(√x)^2 ≥ 11^2

And we know that:

√(x^2) = (√x)^2 = x

Then:

x ≥ 11^2

x ≥ 121

So we only need to have x equal or larger than 121.

The correct option is B.

We can read that value from the graph. It is the y-intercept of the function f(x):

Answer:

56π

Step-by-step explanation:

1. Approach

To find the radius of a circle, use the formula;

[tex]A = r^{2}[/tex]π

To find the area of the shaded region, find the area of the larger circle, and then subtract the area of the smaller circle from it.

It is given that the larger circle has a radius of 9, and the smaller has a radius of 5.

2. Area of the larger circle

[tex]A = r^{2}[/tex]π

Substitute in known value (use 3.14 for π)

[tex]A = (9)^{2} * 3.14[/tex]

A = 254.47

3. Area of the smaller circle

[tex]A = r^{2}[/tex]π

Substitute in known value (use 3.14 for π)

[tex]A = (5)^{2} * 3.14[/tex]

A = 78.54

4. Area of the shaded region

Subtract the area of the smaller circle from the area of the larger circle;

254.47 - 78.54 = 175.93

express y in terms of x​

Answers

Answer:

[tex]\displaystyle y = x^{-\frac{2}{3}}[/tex]

Step-by-step explanation:

Logarithms

Some properties of logarithms will be useful to solve this problem:

1. [tex]\log(pq)=\log p+\log q[/tex]

2. [tex]\displaystyle \log_pq=\frac{1}{\log_qp}[/tex]

3. [tex]\displaystyle \log p^q=q\log p[/tex]

We are given the equation:

[tex]\displaystyle \log_{2}(x) = \frac{3}{ \log_{xy}(2) }[/tex]

Applying the second property:

[tex]\displaystyle \log_{xy}(2)=\frac{1}{ \log_{2}(xy)}[/tex]

Substituting:

[tex]\displaystyle \log_{2}(x) = 3\log_{2}(xy)[/tex]

Applying the first property:

[tex]\displaystyle \log_{2}(x) = 3(\log_{2}(x)+\log_{2}(y))[/tex]

Operating:

[tex]\displaystyle \log_{2}(x) = 3\log_{2}(x)+3\log_{2}(y)[/tex]

Rearranging:

[tex]\displaystyle \log_{2}(x) - 3\log_{2}(x)=3\log_{2}(y)[/tex]

Simplifying:

[tex]\displaystyle -2\log_{2}(x) =3\log_{2}(y)[/tex]

Dividing by 3:

[tex]\displaystyle \log_{2}(y)=\frac{-2\log_{2}(x)}{3}[/tex]

Applying the third property:

[tex]\displaystyle \log_{2}(y)=\log_{2}\left(x^{-\frac{2}{3}}\right)[/tex]

Applying inverse logs:

[tex]\boxed{y = x^{-\frac{2}{3}}}[/tex]

Answers

Answer: X = -10
Y = 6
Step by step:
*is in picture*

Answer:

y=6. &. x = -10

Step-by-step explanation:

if 4x + 5y = -10

then 4x = -10 -5y. ---------->(1)

if 4x + 3y = -22

then 4x = -22 -3y. ------------>(2)

from equation (1) & (2) :

then -10 -5y = -22 -3y

then 22 -10 = 5y -3y

12 = 2y

then y=6

substituting in (1) or (2):

then. x= -10

You have $20. This week, you choose to put 10% in your piggy bank. Next week, you decide to put 10% of your money in your bank again. How much money do you have left to spend?

Answers

Answer:

the amount left is 16.2

Step-by-step explanation:

The computation of the amount of money spend is shown below;

Given that

Total money available $20

This week 10% would be put in piggy bank

and, in next week 10% of the money would be put again in piggy bank

So the money left is

= $20 - $20 × 10% - ($18 × 10%)

= $20 - $2 - $1.8

= $16.2

Hence, the amount left is 16.2
