, there can be 0 , 1 , or 2 solutions<span> to a quadratic equation, depending on whether the expression inside the square root sign, (b </span>2<span> - 4ac) , is positive, negative, or zero</span>

Here is an easy way to remember, If the discriminant is equal to zero there will be one solution, if the discriminant is less than 0 or negative there are no real solutions, more than 0 or positive there will be two. So one real solution if it is equal

Answer:

opposite: 4.88
adjacent: 14.18

Step-by-step explanation:

SOH CAH TOA is a mnemonic intended to remind you of the relevant trig relations.

Sin = Opposite/Hypotenuse ⇒ opposite = 15×sin(19°) ≈ 4.88 units

Cos = Adjacent/Hypotenuse ⇒ adjacent = 15×cos(19°) ≈ 14.18 units

Leo drew a line that is perpendicular to the line shown on the grid and passes through point (F. G). Which of the following is t

tensa zangetsu [6.8K]

The equation of the perpendicular line drawn by Leo is $y-G=\dfrac{-1}{2}(x-F)$ . Option C is the correct answer.

<h3>How to determine the equation of a line?</h3>

A line is drawn perpendicular to the line shown in the image. The perpendicular line passes through the coordinate point (F,G).

The slope of the line from the graph is-

$m=\dfrac{y-intercept}{x-intercept}\\\\\\m=2$

Therefore, the slope of the perpendicular line is $\dfrac{-1}{2}$ .

Also, it is being given that Leo's line is passing through the coordinate point .

So, the equation of the Leo's line is-

$y-G=\dfrac{-1}{2}(x-F)$

Thus, the equation of the perpendicular line drawn by Leo is .

$y-G=\dfrac{-1}{2}(x-F)$

Find the area of the figure. round your answer to the nearest hundredth

liraira [26]

Answer: 84.14

Step-by-step explanation:

Area of the rectangle is L*W=B*H

14*5=70

To find the area of the half circle we must use the formula pi r^2/2

r=radius

and the radius is 6 because we add 4 and 4 and need to get to 14

because the line below it is 14 and it is a rectangle so the lengths are the same.

Diameter=6

So radius =3

pi (3)^2/2=

9/2 pi + 70=
