A car travels along a hill inclined 12º with the horizontal for a distance of 1200 feet. What is the horizontal distance traveled by the car during this time?

Answer:

2.24%

Step-by-step explanation:

Given that :

Actual height = 68.5

Measured height = 67

Percentage error :

(Error value / True value) * 100%

Error = Actual - observed = (68.5 - 67) = 1.5

Percentage error :

(1.5 / 67) * 100%

0.0223880 * 100%

= 2.2388%

= 2.24%

The one-sided limits around the discontinuity shown in the graph are infinity and zero i.e. option 2.

Discontinuous functions are functions that do not have a continuous curve - there is a hole or jump in the graph.

In the shown graph of the function, the function is discontinuous at x=-3

[tex]\lim_{x \to \ -3} g(x)[/tex] tends to infinity so [tex]\lim_{x \to \ -3} g(x)[/tex] does not exist.

[tex]\lim_{x \to \ +3} g(x)=0[/tex]

Hence, the one-sided limits around the discontinuity shown in the graph are infinity and zero i.e. option 2.

Answer:

y=2x+4

Step-by-step explanation:

If the line has a slope of two, that means it goes up 2 on the y axis for every 1 on the x axis. So, if it goes through (1,6), then you can subtract 1 from the x axis and two from the y axis to find the y intercept, (0,4).

Answer:

x=1.5

Step-by-step explanation:

5x + 2 = 3x + 3

subtract 2 from both sides

5x + 2 - 2 = 3x + 3 - 2

simplify

5x = 3x + 1

subtract 3x from both sides

5x - 3x = 3x + 1 - 3x

2x = 1

divide both sides by 2

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

simplify

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

[tex]\frac{1}{2}[/tex]/1.5

Answer:

0.98

Step-by-step explanation:

Below is a drawing of the triangle (drawing it out is an important step if you have trouble visualizing it).

Sine = opposite/hypotenuse, in this case, SR (60) is the opposite of angle Q and RQ (61) is the hypotenuse.

Sin(angle Q) = 60/61 = 0.98

Step-by-step explanation:

3(5x - 4) needs to be simplified

So we multiply 5x by 3

So 3 x 5x = 15x

Then we multiply -4 by 3

3 x -4 = - 12

Put those together we get 15x - 12

The same equation as the one on the right side

So since 15x - 12 = 15x - 12, the x variable can be any number

Answer:

[tex]1.9[/tex]

the cost of the hamburger will be [tex]\$1.9[/tex] if no toppings are added.

Step-by-step explanation:

The function is

[tex]f(t)=1.9+1.4t[/tex]

Let cost of toppings be [tex]y[/tex]

[tex]y=1.9+1.4t[/tex]

The y-intercept of a function is the value of the function when [tex]x=0[/tex]. Here number of toppings [tex]t=0[/tex].

So, the intercept of the function is [tex]1.9[/tex]

This means the cost of the hamburger will be [tex]\$1.9[/tex] if no toppings are added.

Answer:

78.5

Step-by-step explanation:

The formula for the area of a circle is A=πr^2.  The radius, (r) is half of the diameter.  The diameter of this circle is 10 in, so the radius is 5 in.  Plug 5 into the formula A=πr^2 to get A=π5^2.  Square 5 to get 25 and plug it back in the formula to have A=25π.  Multiply pi (π, 3.14) by 25 to get 78.5.

Answer:

x > 8/15

Step-by-step explanation:

x -1/2x + 1/3 > 3/5​

Combine like terms

2/2x - 1/2x +1/3 > 3/5

1/2x   + 1/3 > 3/5

Subtract 1/3 from each side

1/2x + 1/3 -1/3 > 3/5 -1/3

1/2x  > 3/5 -1/3

Get a common denominator

1/2x > 9/15 - 5/15

1/2x > 4/15

Multiply each side by 2

2 * 1/2x > 4/15 * 2

x > 8/15

The measure of  x and JR are 19 and 33  respectively

From the given parallelogram,

KM = 2KR

Given the following

Hence;

3x - 5  = 2(x+7)

3x - 5 = 2x + 14

3x - 2x = 14 + 5

x = 19

Similarly, JL = 2JR

JR = JL/2

JR = 4x-10/2

JR = 4(19)-10/2

JR = 66/2

JR = 33

Hence the measure of  x and JR are 19 and 33  respectively

Answer:

Part A

71°

Part B

The ladder is been used safely

Step-by-step explanation:

Part A

We solve the above question using Trigonometric function of Cosine

cos x = Adjacent/Hypotenuse

Adjacent = The distance between the house and the bottom of the ladder = 4 feet

Hypotenuse = Length of the ladder = 12 feet

x = Angle

Hence:

cos x = 4/12

cos x = 1/3

x = arc cos (1/3)

x = 70.528779366°

Approximately to the nearest degree

= 71°

Part B

According to the manufacturer, if the angle the ladder forms with the ground, x, is between 70° and 75°, then it meets safety standards. Is this ladder being used safely?

Angle x = 71°

Therefore, the ladder is been used safely

Answer: In mathematics, an area model is a rectangular diagram or model used for multiplication and division problems, in which the  or the  and  define the length and width of the rectangle.

We can break one large  of the rectangle into several smaller boxes, using number bonds, to make the calculation easier. Then we add to get the area of the whole, which is the  or quotient.

Step-by-step explanation:

For example, you can find the product 23 × 37 by finding the area of a rectangle with a width of 23 and a length of 37: Of course, there is little gained if you simply multiply 23 × 37! What makes the area model useful is that area is a conserved quantity.

Answer:

Part b.

The line 2x +3y = 1 is tangent to 4x^2 -9y^2 = 19

:

Solve the linear equation for y

:

1) y = -2x/3 +1/3

:

substitute for y in the equation of the hyperbole

:

4x^2 -9(-2x/3 +1/3)^2 = 19

:

4x^2 -9(4x^2/9 -4x/9 +1/9) = 19

:

4x^2 -4x^2 +4x -1 = 19

:

4x -20 = 0

:

4x = 20

:

x = 5

:

use equation 1 to get the value of y
