PLEASE HELP ME I DON’T UNDERSTAND

Answer:

5h>15

Step-by-step explanation:

✓From the question, we were informed that Lucy walks at a rate of 5 miles per hour, this implies that 5 is multiplied by amount of hours (5×1h)= 5h

✓ we need to find the inequality that Lucy can use to find H the number of hours she should walk in order to meet or exceed her goal, To find this as equation, we know that Lucy must walk for at least 15 miles which implies that the (5h) will always be greater than 15 miles. We can put it in equation as

5h>15

NOTE: Inequality provide the relation that exist between two unequal expression. Using notation such as

≠ , >, < ‘less than

Integrate both sides with respect to t :

∫ dy/dt dt = ∫ -12t ² dt

y(t) = -4t ³ + C

Use the initial condition to solve for C :

5 = -4•0³+ C

C = 5

So

y(t) = -4t ³ + 5

and the answer is D.

Alternatively, you can directly apply the fundamental theorem of calculus:

[tex]\dfrac{\mathrm dy}{\mathrm dt}=-12t^2\implies y(t)=y(0)+\displaystyle\int_0^t -12u^2\,\mathrm du[/tex]

[tex]\implies y(t)=5-4u^3\bigg|_0^t[/tex]

[tex]\implies y(t)=5-4t^3[/tex]

The value of B is 16.

The correct option is B

A basic quadratic equation, or a second-order polynomial equation with a single variable, is represented by the equation x : ax² + bx + c = 0, where a≠0 for the variable x. As it is a second-order polynomial equation, which is ensured by the algebraic fundamental theorem, it must have at least one solution.

The standard equation for a hyperbola centered at the origin is:

(x²)/(a²) - (y²)/(b²) = 1

where "a" and "b" are the lengths of the transverse and conjugate axes, respectively. To find the value of "b" for the given hyperbola equation, we need to first rewrite it in the standard form.

(x²)/(24²) - (y²)/(b²) = 1

Multiplying both sides by (24²)(b²), we get:

b²(x²) - (24²)(y²) = (24²)(b²)

Dividing both sides by (24²), we get:

b²(x²)/(24²) - y² = b²

Comparing this with the standard equation, we can see that a = 24 and b is the square root of the constant term, which is b² = 576. Therefore, b = 24.

However, the given directrix of x = 576/26 is not consistent with the equation of the hyperbola. The directrix for a hyperbola with center at the origin and transverse axis along the x-axis is given by x = a²/b. Using the value of a = 24, we can find the directrix as:

x = (24²)/b

Setting this equal to 576/26, we get:

(24²)/b = 576/26

Solving for b, we get:

b = 16

Therefore, the correct answer is (B) 16.

Answer: $69

Step-by-step explanation: For every hour ray works over 40 hours, he makes an additional $7.50. According to part B, Ray calculated incorrectly that he earned $45 of additional pay. His error when he calculated incorrectly his overtime pay was that he didn't mulitply correctly, and that gave him the andwer of $45. So therefore, Ray's paycheck for working 46 hours was $69. How I found out my answer I did 150% times 46 which gave me 6,900. After that I divided 6,900 by 100 which gave me 69. If we wanna check our answer we can always divide 69 and 46 hours and get 150%. So In Conclusion, Ray would make more oney working 32 hours a week, and then 46 the next week. We also found this out, because working 32 hours one week ray makes $48, but when he works 46 hours a week, ray makes $69 and when adding those together it makes much more than 40 hours a week for two weeks.

Answer:

$0.15

Step-by-step explanation:

Given that:

Cost of banana per pound = $0.80

Amount of banana bought = [tex]2\frac{1}{4}=2.25\ pounds[/tex]

Cost of strawberries per pound = $1.10

Amount of strawberries bought = [tex]1\frac{1}{2} = 1.5\ pounds[/tex]

To find:

How much more money was spent on bananas than Strawberries.

Solution:

Here, first we need to find how much money was spent on bananas and strawberries.

Then we need to subtract the smaller value from larger value.

From the given values, we can calculate the following:

Cost of banana for 2.25 pounds = $0.80 [tex]\times[/tex] 2.25 = $1.8

Similarly,

Cost of strawberries for 1.5 pounds = $1.10 [tex]\times[/tex] 1.5 = $1.65

Money more spent on bananas = $1.8 -  $1.65 = $0.15

Answer:

x=29

Step-by-step explanation:

because the two sides of the acute triangle are the same length, the ones at the bottom are the same as well. the total of the angles of a triangle is 180, and we know that one of the angles are 64 so we subtract that from 180 and get 116 which we divide by two to get the other two angles: 58 and 58. at the bottom of the image, two angles are connected and make a straight 180 line so we can take 58 out of that 180 and get 122 in the obtuse angle and divide by two to get 29 in the acute angles of the obtuse triangle.

What are the possible answer??/

Step-by-step explanation:

The set of points satisfying the equation y = 2x - 3 is a. {(0, -3), (1, -1), (1.5, 0), (2,1)}.

An equation is the combination of 2 or more expressions separated by the equality sign(=), signifying the equality of expressions.

To obtain the set of points satisfying the equation y = 2x - 3.

The given equation is y = 2x - 3.

Let's take x = 0,

y = 2 × 0 - 3 = -3,

the point is (0, -3).

Let's take y = 0,

0 = 2x - 3

2x = 3

x = [tex]\frac{3}{2}[/tex]

x = 1.5,

the point is (1.5, 0).

Let's take x = 1,

y = 2 × 1 - 3 = -1,

the point is (1, -1).

Let's take y = 1,

1 = 2x - 3

2x = 1 + 3

2x = 4

x = [tex]\frac{4}{2}[/tex]

x = 2,

the point is (2,1).

Hence, the set of points satisfying the equation is {(0, -3), (1, -1), (1.5, 0), (2,1)}.

Step-by-step explanation:

Answer:

The equation, y=3x-5 is in y=mx+b format. The b, or -5 in this case, tells you what the y intercept is, or in this case, your starting point. This means your first point will be at (0,-5). The mx, or 3x in this case, tell us how much to move     up and how much to move sideways. 3x is equal to 3/1x and the 3/1 tells us the rise/run. Rise being how much to go up or down and run being how much to go to the left or right. So in 3x, the rise is 3 and the run is 1. So you will go 3 up on the y axis and 1 to the right on the x-axis. So your next point will be (1, -2) and the point after that will be (2, 1) and so on!

Answer:

Step-by-step explanation:

y=3x-5 is a line

pick any 2 points for example

(x=0, y=(3*0)-5=-5) so one point is (0,-5)

(x=2, y=(3*2)-5= 1) so another point is (2, 1)

Answer:

See answer below

Step-by-step explanation:

Given the expressions

8 × 1/9, 4 × 4/5, 6 × 1/5, 9 × 1/2, 1 × 2/5, 9 × 1/9

We are to check which is less than 1, equal to 1 and greater than 1

For 8×1/9

8×1/9 = 8/9

8/9 = 0.889<1

Hence 8/9 is less than 1

For 4 × 4/5

4 × 4/5 = 16/5

16/5 = 3 1/5

3 1/5 =3.2>1

Hence 4 4/5 is greater than 1

For 6×1/5;

6×1/5 = 6/5

6/5 = 1.2 >1

Hence 6×1/5 is greater than 1

For 9 × 1/2:

9 × 1/2 = 9/2

9/2 = 4.5>1

Hence 9× 1/2 is greater than 1

For 1×2/5;

1×2/5 = 2/5

2/5 = 0.4<1

Hence 1×2/5 is less than 1

For 9×1/9

9×1/9 = 9/9

9/9 = 1

Hence 9×1/9 is equal to 1
