7. The jib sail of a yacht is

Rom4ik [11]

Answer:

Pytagora's Theorem

Step-by-step explanation

a = 4 m

b = 15 m

c = ?

a^2 + b^2 = c^2

√ a^2 + b^2 = c

a^2 = 16 m

b^2 = 225 m

√ 16 + 225 = c

√ 241 = 15.52 m

c = 15.52 m

Prove using the Pythagorean theorem that AC is perpendicular to AB given points ????(−2, −2), ????(5, −2), and

Tems11 [23]

Answer:

$(BC)^2=(AC)^2+(AB)^2$ . It means AC is perpendicular to AB.

Step-by-step explanation:

Vertices of given triangle are A(−2, −2), B(5, −2), and C(−2,22).

Distance formula:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Using distance formula we get

$AB=\sqrt{(5-(-2))^2+(-2-(-2))^2}=\sqrt{7^2}=7$

$BC=\sqrt{(-2-5)^2+(22-(-2))^2}=\sqrt{7^2+24^2}=\sqrt{625}=25$

$AC=\sqrt{(-2-(-2))^2+(22-(-2))^2}=\sqrt{24^2}=24$

According to Pythagoras theorem

$hypotenuse^2=perpendicular^2+base^2$

$(BC)^2=(AC)^2+(AB)^2$

Perpendicular = AC

Base = AB

It means AC is perpendicular to AB.

Hence proved.

Total annual premium for health insurance for Martina is 7705. Her employer pays 90% of the premium and the ducks the remainder

anzhelika [568]

Answer:

$29.63

Step-by-step explanation:

The total amount deducted from Martina's paycheck annually is;

10% of 7705 which is equivalent to 770.5.

Considering that she is paid biweekly, we divide this amount by 26 which is the approximate number of biweekly periods in a year;

770.5/26 = 29.63

Therefore, $29.63 is deducted from her biweekly paycheck for health insurance

Do you have a picture of what the graph would look like?

Keith_Richards [23]

The attached graph represents the piecewise function.

<h3>How to determine the graph of the equation?</h3>

The piecewise function is given as:

f(x) = 3x - 5, x ≤ -1

= -2x + 3, -1 < x < 4

= 2, x ≥ 4

To plot the graph, we simply plot the equations together with their domains

i.e.

3x - 5 with the domain of x ≤ -1, -2x + 3 with the domain of -1 < x < 4 and 2 with the domain of x ≥ 4

See attachment for the graph of the function
