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

It's either B or A. It's probably A tho.

Answer:

x= 5

Step-by-step explanation:

Answer:

x = 5

Step-by-step explanation:

As it is an isosceles triangle so two sides BA and BC are equal. So,

BA = BC

3x + 3 = 2x + 8

3x - 2x = 8 - 3

x = 5

Therefore AC = 5

The number that is less than 1.25 is 1.2.

The given number is a decimal.  A decimal is a number that is made up of a whole number and fractional parts divided by a point. For example in 1.25, 1 is the whole number and 2 and 5 are the fractional parts.

The number that is greater than 1.25 would have either its tenth value greater than 2 or its hundredth value greater than 5. The number less than 1.25 would have either its tenth value less than 2 or its hundredth value less than 5.

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:

78.53

Step-by-step explanation:

[tex]\pi[/tex] x [tex]5^{2}[/tex]

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:

Yes, (0, 1) is the solution of the given inequality.

Step-by-step explanation:

To find whether the given ordered pair is a solution of the linear inequality, we will satisfy the inequality with the coordinates of the ordered pair.

If the inequality is true for the ordered pair it will be the solution.

Inequality is,

y > x - 1

For (0, 1),

1 > 0 - 1

1 > -1

True.

Therefore, ordered pair (0, 1) is the solution of the given inequality.

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

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]

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%

Answer:

Infinite Solutions

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
