Answer:

f^-1(x) = ( x + -1 )³

Step-by-step explanation:

f(x) = ∛x + 1

y  = ∛x + 1

we have to make x the subject to find the inverse

y  = ∛x + 1

y - 1 = ∛x

( y - 1 )³ = x

so Inverse: f^-1(x) = ( x + -1 )³

Answer:

  x ≈ 263.1

Step-by-step explanation:

The marked sides are the hypotenuse and the side adjacent to the given angle. The relevant trig relation is ...

  Cos = Adjacent/Hypotenuse

  cos(70°) = 90/x . . . . use given values

  x = 90/cos(70°) . . . . multiply by x/cos(70°)

  x ≈ 263.1

_____

Additional comment

The mnemonic SOH CAH TOA is intended to remind you of the primary trig relations:

  Sin = Opposite/Hypotenuse

  Cos = Adjacent/Hypotenuse

  Tan = Opposite/Adjacent

Answer: The new point would be (2,-1)

Step-by-step explanation:

To dilate a point, you simply multiply the scale factor (1/3) by the x- and y-values of the point:

6 x 1/3 = 2

-3 x 1/3 = -1

Therefore, the new point would be (2,-1)

Answer:

  (d)  y= (1 1/9)x

Step-by-step explanation:

A proportional relation is described by the equation ...

  y = kx

Dividing by x shows how to find the value of k:

  k = y/x

For the given values of y and x, the value of k is found to be ...

  k = (5/6)/(3/4) = (5/6)(4/3) = 20/18 = 10/9 = 1 1/9

The relationship is represented by the equation ...

Answer:

Yes

Step-by-step explanation:

To see if (2,0) works as a solution to the systems of equations, we plug in the values of x and y and simplify. If the results are equal, then (2,0) is a solution.

3x + y = 6:

3x - y = 6:

Answer:

  (a) 7.1

  (b) (5/2, 3/2)

  (c) 2

  (d) y = -x +4

Step-by-step explanation:

The length of AC is found using the distance formula:

  d = √((x2 -x1)² +(y2 -y1)²)

  d = √((5 -(-2))² +(-1 -0)²) = √(49 +1) = 5√2 ≈ 7.1

The length of AC is about 7.1.

The midpoint has coordinates that are the average of the end point coordinates.

  midpoint BC = (B + C)/2 = ((0, 4) +(5, -1))/2 = (5, 3)/2

  midpoint BC = (5/2, 3/2)

__

The slope is found using the slope formula.

  m = (y2 -y1)/(x2 -x1)

For points A(-2, 0) and B(0, 4), the slope of the segment between them is ...

  m = (4 -0)/(0 -(-2)) = 4/2 = 2

The slope of AB is 2.

__

The slope of line BC is found in the same was as for AB.

  m = (-1 -4)/(5 -0) = -5/5 = -1

The y-intercept of the line is point B, at y=4. So, the equation of line BC is ...

  y = mx +b . . . . . where m is the slope, and b is the y-intercept

  y = -x +4

Answer:

y = 2x + 5

Step-by-step explanation:

Consider the format of a line equation, y = mx + b

The slope is represented as the variable 'm.'

Since we already know that the slope is 2, we can input it into the format.

y = 2x + b

Assuming that the point (14, 33) is a point of intersection, we can input these numbers into the equation in order to find the value of b, or the y-intersect.

33 = 2(14) + b

33 = 28 + b

5 = b

The length of the square paving is the base unit to which the area of the

and patio and the border are evaluated.

Correct response:

Let s represent the size of the square paving, we have;

Area of the patio = s·x × s·y = s²·x·y

New area = (2·s + s·x) × (2·s + s·y) = 4·s² + 2·s²·y + 2·x·s² + s²·x·y

Area of the border = 4·s² + 2·s²·y + 2·x·s² = s²·x·y

2·s²·(2 + y + x) = s²·x·y

2·(2 + y + x) = x·y

4 + 2·y + 2·x = x·y

x·y - 2·x = 4 + 2·y

x·(y - 2) = 4 + 2·y

Which by using  gives;

[tex]x = \mathbf{ \dfrac{4 + 2 \cdot y }{y- 2}}[/tex]

5x-2x=4x-x (then moving everything to one side)

[tex]3(7550)=7550e^{0.0725\cdot t}\implies \cfrac{3(7550)}{7550}=e^{0.0725t}\implies 3=e^{0.0725t} \\\\\\ \log_e(3)=\log_e\left( e^{0.0725t} \right)\implies \ln(3)=0.0725t \\\\\\ \cfrac{\ln(3)}{0.0725}=t\implies 15.15327\approx t\implies 15\approx t[/tex]

It will take approximately 9.55 years (rounded to the nearest year) for the money to triple.

Here, we have,

To determine how long it will take for the money to triple, we need to use the continuous compound interest formula:

A = P *[tex]e^{rt}[/tex],

where:

A = final amount (triple the initial amount)

P = principal amount (initial deposit)

e = Euler's number (approximately 2.71828)

r = interest rate

t = time (in years)

In this case, we have:

P = $7550

r = 7.25% = 0.0725 (converted to decimal)

A = 3P (triple the initial amount)

Substituting these values into the formula, we have:

3P = P *[tex]e^{rt}[/tex]

Dividing both sides of the equation by P, we get:

3 = [tex]e^{rt}[/tex]

To isolate the variable t, we take the natural logarithm (ln) of both sides:

ln(3) = ln[tex]e^{rt}[/tex]

Using the logarithmic property that ln(eˣ) = x, we have:

ln(3) = rt * ln(e)

Since ln(e) = 1, the equation simplifies to:

ln(3) = rt

Now, we can solve for t by dividing both sides by r:

t = ln(3) / r

Substituting the values:

t = ln(3) / 0.0725

Using a calculator or software, we find:

t ≈ 9.55 years (rounded to two decit will take approximately 9.55 years (rounded to the nearest year) for the money to triple. deimal places)

Therefore, it will take approximately 9.55 years (rounded to the nearest year) for the money to triple.

Answer:

x ≈ 33.0

Step-by-step explanation:

The third angle in the triangle is

180° - 70° - 76° = 180° - 146° = 34°

Using the Sine rule in the triangle

[tex]\frac{x}{sin76}[/tex] = [tex]\frac{19}{sin34}[/tex] ( cross- multiply )

x × sin34° = 19 × sin76° ( divide both sides by sin34° )

x = [tex]\frac{19sin76}{sin34}[/tex] ≈ 33.0 ( to the nearest tenth )

Answer:

x=33 (since it says to round it)

Step-by-step explanation:

This is an ASA triangle.

First, we need to find the value of the unlabeled angle, which is simple:

180°-70°-76°=34°  Lets call that angle A

Now we use the law of sines:

x/sinX = a/sinA

x/sin76° = 19/sin34°

Then:

x = (19/sin34°) × sin76°

x = 32.968

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Let the cost of 2 pair of boots be A

Now , the cost of pair of boots = 145 % the cost of pair of sneakers

Substituting the values in the equation , we get

The cost of pair of sneakers = $ 21

So , the cost of pair of boots = ( 1.45 ) x 21

The cost of pair of boots = $ 30.45

Now , the cost of 2 pair of boots A = 2 x cost of pair of boots

On simplifying , we get

The cost of 2 pair of boots A = $ 60.90
