Answers

Answer 1

Answer:

Lena can buy candy in infinite no of ways with the possible amounts:-

1 pound of candy = $7

1.1 pound of candy = $7.7

2 pounds of candy = $14

3 pounds of candy = $21

4 pounds of candy = $28

5 pounds of candy = $35

6 pounds of candy = $42

7 pounds of candy = $49

8 pounds of candy = $56

9 pounds of candy = $63

10 pounds of candy = $70

11 pounds of candy = $77

11.9 pounds of candy = $83.3

State the slope and y-intercept for the graph of
- 8x + y = -12.

Answers

Answer:

y must have a numerical coefficient of 1. This equation does. If it does not, then you must divide through by whatever is in front of the y.

To read the slope, you must have x and its coefficient on opposite sides of the equal sign.

So you get

y = 8x – 12 when you add 8x to both sides

Next, the y intercept is found when x = 0

y = 8x – 12

y = 8(0) – 12

y = – 12

The y intercept is -12 or in point form (0, – 12)

Answer

slope = 8

y intercept = – 12

Write an exponential function in the form y

Answers

Answer:

y = 2·5^x

Step-by-step explanation:

Using the given points, we can solve for 'a' and 'b'.

y = ab^x

2 = ab^0 = a . . . . . substitute (0, 2) for (x, y)

1250 = 2·b^4 . . . . substitute for 'a' and (4, 1250) for (x, y)

625 = b^4 . . . . divide by 2

5 = b . . . . . . . take the 4th root

The function is ...

y = 2·5^x

Additional comment

There are two real and two imaginary 4th roots of 625. Only the positive real root is useful as the base in an exponential function like this.

Solve. \sqrt{8x} -8-8=4

Answers

Answer:

x=50

Step-by-step explanation:

Let's solve your equation step-by-step.

√8x - 8 - 8 = 4

√8x - 16 = 4

Step 1: Add 16 to both sides.

√8x - 16 + 16 = 4 + 16

√8x = 20

Step 2: Solve Square Root.

√8x = 20

8x = 20^2 ( Square both sides )

8x = 400

8x/8 = 400/8 (Divide both sides by 8)

x = 50

In a lab experiment, 5300 bacteria are placed in a petri dish. The conditions are such
that the number of bacteria is able to double every 23 hours. How long would it be, to
the nearest tenth of an hour, until there are 10500 bacteria present?

Answers

Answer: x = 22.7

Step-by-step explanation:Based on the given conditions, formulate: 5300x2(x divided by 23) = 10500

Divide both sides of the equation by the coefficient of variable: 2 x/23 = 10500/5300

Reduce the fraction:2 x/23 = 105/53

Convert exponential to logarithm form: x/23 = long^2 105/53

Divide both sides of the equation by the coefficient of variable:x = log^2 105/53 x 23

Rewrite the expression: x = 23 long^2 105/53

Round the number: x = 22.7

Answer: x = 22.7

Answers

Answer:

A) 1: linear; 2: exponential (see equations in part B)

B) the value of 2 will be almost 15% greater

Step-by-step explanation:

Part A:

As is often the case with multi-part questions, later parts of the question answer earlier parts. The equations shown in Part B are linear for Option 1 and exponential for Option 2.

The table values for Option 1 have a common difference of (1200 -1100) = 100.

The table values for Option 2 have a common ratio of (1210/1100) = 1.10.

Linear functions produce sequential values with a common difference (the slope of the function). Option 1 is linear.

Exponential functions produce sequential values with a common ratio (the growth factor). Option 2 is exponential.

Part B:

The investment values after 7 years will be ...

Option 1: f(7) = 100(7) +1000 = 1700

Option 2: g(7) = 1000(1.1^7) ≈ 1948.72

The value of Option 2 will be about $248.72 higher, or 14.6% higher than the value of Option 1. Whether that is significant or not is in the eye of the beholder. Many people might consider that to be significantly better performance. (It would take another 2 1/2 years for Option 1 to have that value.)

A jacket is on sale for $48 in a Texas store. The sales tax in Texas is 6,25%.
How much does the jacket cost with sales tax included? *

Answers

Answer:

$51

Step-by-step explanation:

First, we can convert the tax to a decimal by dividing by 100.

6.25% = 0.0625

Then, we can calculate the sales tax by multiplying the original amount by the tax.

48 * 0.0625 = 3

Finally, we can add the sales tax to the original amount to get our final amount of

48 + 3 = 51

Answers

Answer:

y = -0.6x +109

Step-by-step explanation:

The slope is given by the formula ...

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

m = (88 -94)/(35 -25) = -6/10 = -0.6

The y-intercept is ...

b = y -mx = 94 -(-0.6)(25) = 109

The equation of the line is ...

y = mx +b

y = -0.6x +109

If y = ax + 2a², then its derivative is dy/dx = a. Substitute y and dy/dx into the given equation and check if it results in an identity:

2 (dy/dx)² + x dy/dx - y = 0

2a² + ax - (ax + 2a²) = 0

0 = 0

This is of course true, so y = ax + 2a² is indeed a solution to the given equation.

A skyscraper is 396 meters tall. At a certain time of day, it casts a shadow that is 332 meters long. At what angle is the sun above the horizon at that time?

Answers

Step-by-step explanation:

there is a right-angled triangle.

its legs (enclosing the 90° angle) are the height of the skyscraper (396 m) and the shadow (332 m).

so, we know the third side (the Hypotenuse, which is the line of sight between the end of the shadow and the top of the skyscraper) too by using Pythagoras :

c² = a² + b²

line² = 396² + 332² = 156816 + 110224 = 267040

line = sqrt(267040) = 516.7591315... m

and we know 1 angle : the 90° angle between the legs.

the other angles we can now get by using the law of the sines :

a/sin(A) = b/sin(B) = c/sin(C)

where the angles are opposite of the lines.

the line of sight is opposite of the 90° angle.

and the height of the skyscraper is opposite of the angle between the line of sight and the shadow. this angle is also the angle of the sun above the horizon, as the extended line of sight would lead directly to the sun.

so, we have

516.7591315.../sin(90) = 396/sin(angle)

as sin(90) = 1

516.7591315... = 396/sin(angle)

sin(angle) = 396 / 516.7591315... = 0.76631447...

angle = 50.02407526...°
