Answer:

height = 6.92820323028km (you can round if you want to)

Step-by-step explanation:

8km - 4km = 4km (this is for one of the side lengths of the traingle)

a² + b² = c²

4² + b² = 8² (b will be used to represent the height)

16 + b² = 64

b² = 48

b = 6.92820323028km

What is the point slope form of a line that has a slope of 3 and passes through the point (-1,4)
lukranit [14]

Answer:

y - 4 = 3(x- (-1)     --->      y-4 = 3(x+1)

Step-by-step explanation:

y - 4 = 3(x + 1)

y - 4 = 3x + 3

y = 3x + 7

then plug in (-1,4)

4 = 3(-1) + 7

4 = -3 + 7

4 = 4

Point slope form looks like:

y - y₁ = m(x - x₁)

Mrs Franklin's speedometer said she was driving at a rate of 48 miles per hour. When checking the accuracy of her speedometer, a
Ket [755]

The percent error is 4.167 %

<em><u>Solution:</u></em>

Given that, Mrs Franklin's speedometer said she was driving at a rate of 48 miles per hour

When checking the accuracy of her speedometer, an Automotive Specialist recorded her speed at 50 miles per hour

<em><u>The percent error is given by formula:</u></em>

Percent error is the difference between a measured and known value, divided by the known value, multiplied by 100%

\text{Percent error } = \frac{\text{experimental-theoretical}}{theoretical} \times 100

From given,

Experimental value = 50

Theoretical value = 48

<em><u>Substituting the values in formula, we get,</u></em>

Percent\ Error = \frac{50-48}{48} \times 100\\\\Percent\ Error = \frac{2}{48} \times 100\\\\Percent\ Error = 4.167

Thus the percent error is 4.167 %

What is the domain of F(x) = 1/x ?
Elenna [48]

Step-by-step explanation:

The domain is the possible x values of a function.

Since our function is a reciprocal function, our denominator can't equal 0. Note x=0, is a vertical asymptote.

So our domain is

All Reals except 0,

or (-oo,0) U (0, oo).
