Answer:

60%

Step-by-step explanation:

its right

If a company’s stock was selling at 35$ a share. a month later it was selling at 14$ a share then the percent of loss is 60%.

percentage, a relative value indicating hundredth parts of any quantity.

Given that a company’s stock was selling at 35$ a share.

After a month later it was selling at 14$ a share.

We need to find the percent of loss.

Original share price=35

new share price=14

We calculate the percentage by finding the difference and dividing the difference with the original share price.

35-14/35

0.6

Now multiply this 0.6 with 100 as it is a hundredth part.

0.6×100

60%

Hence, if a company’s stock was selling at 35$ a share. a month later it was selling at 14$ a share then the percent of loss is 60%.

Answer:

∠ EFG = 83°, ∠ GCE = 97°

Step-by-step explanation:

Since FE and FG are tangents to the circle then

∠ FGC and ∠ FEC are right angles

The sum of the angles in quadrilateral CEFG = 360°

Sum the 4 angles and equate to 360

3x + 11 + 90 + 5x - 23 + 90 = 360, that is

8x + 168 = 360 ( subtract 168 from both sides )

8x = 192 ( divide both sides by 8 )

x = 24

Thus

∠ EFG = 3x + 11 = 3(24) + 11 = 72 + 11 = 83°

∠ GCE = 5x - 23 = 5(24) - 23 = 120 - 23 = 97°

Answer:

y = 51-0.4x

Step-by-step explanation:

From the question, we can see that the amount of water left in the pool was 45 inches deep within 12:15-12:00 = 15 minutes

However, within 10 minutes there was a loss of 45-41 = 4 inches

So what this means is that per minute, the amount of loss expected is 4 inches/10 minutes = 0.4 inches per minute

what we are saying is that a loss of 4 inches depth of water is needed per minute

So we want to write an equation, representing the depth after x minutes

So what we have here is that the total inches at present will be;

45 + 0.4(15) = 45 + 6 = 51 inches

The pool was 51 inches deep initially before the pumping out began

That will be;

y = 51-0.4x

where is the depth and x is the number of minutes

Answer:

24 inches

Answer:

[tex]f^{-1} (x)=x^{2} -3[/tex]

Step-by-step explanation:

Given the function

[tex]f\left(x\right)=\sqrt{x+3}[/tex]

We can find the inverse function by exchanging x and y, and then solve for y.

[tex]y=\sqrt{x+3}[/tex]

Replace x with y.

[tex]x=\sqrt{y+3}[/tex]

square both sides

[tex]x^2=y+3[/tex]

[tex]y=x^2-3[/tex]

Hence,

[tex]f^{-1} (x)=x^{2} -3[/tex]

Answer:

The equation of a line that is parallel to x−2y=−4 and passes through the point (0, 0) will be:  [tex]x-2y=0[/tex]

Step-by-step explanation:

Given the line

[tex]x-2y=-4[/tex]

[tex]x+4 = 2y[/tex]

[tex]y=\left(\frac{1}{2}\right)x+2[/tex]

[tex]m_1=\frac{1}{2}[/tex]

so, the slope of the line parallel to the given line would have

the same slope as  [tex]\frac{1}{2}=m[/tex], and passed through the point (0, 0).

Therefore, the equation of the required line is given by

[tex]y = mx+b[/tex]

[tex]y=\left(\frac{1}{2}\right)x+0[/tex]

[tex]y=\left(\frac{1}{2}\right)x[/tex]

[tex]2y=x[/tex]

[tex]x-2y=0[/tex]

Therefore,  the equation of a line that is parallel to x−2y=−4 and passes through the point (0, 0) will be:  [tex]x-2y=0[/tex]

We want the equation in the form y = mx + b.

We are given that m = -7.

The y-intercept (our b) is 8.

Here it is:

y = -7x + 8

Answer:

[tex]y = 4^x[/tex]

Step-by-step explanation:

Given

[tex](2,16)[/tex]

[tex](5,1,024)[/tex]

Required

Determine the exponential function [tex]y = a.b^x[/tex]

In [tex](2,16)[/tex]

[tex]x=2[/tex] and [tex]y = 16[/tex]

Substitute these values in [tex]y = a.b^x[/tex]

[tex]16 = a.b^2[/tex] --- (1)

In [tex](5,1,024)[/tex]

[tex]x = 5[/tex] and [tex]y = 1024[/tex]

Substitute these values in [tex]y = a.b^x[/tex]

[tex]1024 = a.b^5[/tex] --- (2)

Divide (2) by (1)

[tex]\frac{1024}{16} = \frac{a.b^5}{a.b^2}[/tex]

[tex]\frac{1024}{16} = \frac{b^5}{b^2}[/tex]

[tex]64 = \frac{b^5}{b^2}[/tex]

Apply second law of indices

[tex]64 = b^{5-2[/tex]

[tex]64 = b^3[/tex]

Express 64 as an exponent of 3

[tex]4^3 = b^3[/tex]

[tex]4 = b[/tex]

[tex]b = 4[/tex]

Substitute 4 for b in (1)

[tex]16 = a.b^2[/tex]

[tex]16 = a * 4^2[/tex]

[tex]16 = a * 16[/tex]

[tex]16 = 16a[/tex]

Solve for a

[tex]a=\frac{16}{16}[/tex]

[tex]a = 1[/tex]

Substitute 1 for a and 4 for b in [tex]y = a.b^x[/tex]

[tex]y = 1 * 4^x[/tex]

[tex]y = 4^x[/tex]

The exponential function is given by y = 100(0.4)ˣ

An exponential function is in the form:

y = abˣ

where y, x are variables, a is the initial value of y and b is the factor.

At point (2, 16):

16 = ab²      (1)

At point (5, 1.024):

1.024 = ab⁵      (2)

Dividing equation 2 by equation 1:

b³ = 0.064

b = 0.4

16 = a(0.4)²

a = 100

The exponential function is given by: y = 100(0.4)ˣ
