Step-by-step explanation:

Answer:

(2,6)

Step-by-step explanation:

Answer:

dy/dx = d/dx sin(x-3/x+2)

dy/dx = cos(x-3/x+2) . d/dx (x-3/x+2)

dy/dx = cos(x-3/x+2) . (x + 2 - x + 3)/(x+2)²

dy/dx = [5cos(x-3/x+2)]/(x + 2)²

No.

First find the values where f(x) = g(x)

These occur when the graphs intersect

x = -2, -1, 2

These are the points where the graphs intersect

Given the choices of -1,2,3,-2

They do not intersect at 3

Answer:

[tex] \displaystyle 3 {x}^{2} + 4x - 1 = 0[/tex]

Step-by-step explanation:

we are given some coordinates

(1,6),(2,19),(3,38),(4,63),(5,94)

we want to figure out the quadratic equation which passes those coordinates

notice that, the coordinates in quadratic sequence

we know that,

A sequence is quadratic if and only if it has second difference

recall that,

these formulas are necessary to figure out a,b and c

because we know that

Quadratic equation standard form:

[tex] \displaystyle a {x}^{2} + bx + c = 0[/tex]

therefore to figure out a,b and c these formulas are important

let's figure out a:

we got that 2nd difference is 6 thus

[tex] \displaystyle 2a = 6[/tex]

divide both sides by 2

[tex] \displaystyle \frac{2a}{2} =\frac{ 6}{2}[/tex]

[tex] \displaystyle a = 3[/tex]

let's figure out b:

by using the second formula we can figure out b

our [tex]U_1[/tex] and [tex]U_2[/tex] are 6 and 19 respectively

substitute:

[tex] 3 \cdot 3 + b = 19 - 6[/tex]

simplify multiplication:

[tex]9+ b = 19 - 6[/tex]

simplify substraction:

[tex]9+ b = 13[/tex]

cancel 9 from both sides:

[tex]b = 4[/tex]

let's figure out c:

our [tex]U_1[/tex] is 6

substitute:

[tex] \displaystyle 3 + 4 + c = 6[/tex]

simplify addition:

[tex] \displaystyle 7 + c = 6[/tex]

cancel 7 from both sides:

[tex] \displaystyle c = - 1[/tex]

altogether substitute a,b and c to quadratic equation:

[tex] \displaystyle 3 {x}^{2} + 4x - 1 = 0[/tex]

and we are done!

Answer:

D . 2x = 5

Step-by-step explanation:

cause it seems like the hanging thing is in balance -> both sides need to be equal in value. the left side contains 2 x-es, and the right side contains 5 ones.

Answer:

x = -2

Step-by-step explanation:

7(2 - x) = 28

Distribute

14 -7x = 28

Subtract 14 from each side

14-7x-14 = 28-14

-7x = 14

Divide each side by -7

-7x/-7 = 14/-7

x = -2

choose bag b because there is a higher chance that u will get a power of

Answer:

205.2 units

Step-by-step explanation:

If you are solving for the S.A. of a rectangular prism, then simply multiply the numbers together as each stands for length (l), height (h), and width (w).

l*w*h

4.7 * 5.9 * 7.4 = ‭205.202‬

Answer:

[tex] \boxed{Dimensions\: of \: the \: rectangle \: are \: 15 \: and \: 10 units} [/tex]

Step-by-step explanation:

Let the length of rectangle be 'x' units

So, width of rectangle will be = x - 5 units

Area of rectangle = 150 square units

[tex]=> Area \: of \: rectangle = length × breadth \\ \\ = > 150 = x \times (x - 5) \\ \\ = > 150 =( x \times x )- (x \times 5) \\ \\ = > 150 = {x}^{2} - 5x \\ \\ = > 0 = {x}^{2} - 5x - 150 \\ \\ = > {x}^{2} - 5x - 150 = 0 \\ \\ = > {x}^{2} - (15 - 10)x - 150 = 0 \\ \\ = > {x}^{2} - 15x + 10x - 150 = 0 \\ \\ = > x(x - 15) + 10(x - 15) = 0 \\ \\ = > (x - 15)(x + 10) = 0 \\ \\ = > x - 15 = 0 \: \: \: \: \: \: \: \: \: or \: \: \: \: \: \: \: \: \: x + 10 = 0 \\ \\ = > x = 15 \: \: \: \: \: \: \: \: \: \: or \: \: \: \: \: \: \: \: \: x = - 10[/tex]

Dimension cannot be negative so the value of x is 15

Therefore,

Length of rectangle = 15 units

Width of rectangle = 15 - 5 = 10 units

Answer:

A. 240/7

Step-by-step explanation:

10^4x/24 * 10^3x/24 = 10^10

10^7x/24 = 10^10

7x/24 = 10

x = 240/7

Answer: 324 cards.

Step-by-step explanation:

Hi, to answer this question we have to multiply the number of pages in the album (72) by the number of cards that each page holds (9):

Mathematically speaking:

72(9) = 648 cards in the album

Since half of the pages are full, we have to divide the previous result by 2.

648/2 = 324 cards

Feel free to ask for more if needed or if you did not understand something.

Answer:

7920, 2925

Step-by-step explanation:

The four-digit number has to be a multiple of 5 and also a multiple of 9. So, the last number is either a 0 or a 5, and the addition of the 4 digits must be equal to 9, 18, 27, et cetera, like every multiple of 9.

For the case: _920, the addition of digits gives 11, then the only possible first digit is 18-11 = 7

For the case: _925, the addition of digits gives 16, then the only possible first digit is 18-16 = 2

Answer:

y= mx+b

Step-by-step explanation:

Slope intercept formula:

y=mx+b

m= slope

b= y intercept

Answer:

The equation of a horizontal line is y = b where b is the y-intercept. Since the slope of a horizontal line is 0, the general formula for the standard form equation , y = mx + b becomes y = 0x +b y = b. Also,since the line is horizontal, every point on that line has the exact same y value. This y-value is therefore also the y-intercept.
