Answer:

? = $tan^{-1}$ (11/24)

**PUT $tan^{-1}$ (11/24) INTO CALCULATOR

Step-by-step explanation:

1. tan(?)=11/24

--> 11/24: SOH, CAH, TOA: sin(x)=opposite side of the x/hypotenuse, cos=adjacent side of the x/hypotenuse, tan=opposite side of the x/adjacent side

2. to get ? of tan you can't divide tangent, you have to do the inverse function, which is $tan^{-1}$ , and put it into the calculator

AC=4, AE=7, AD=10, what is the length of AB? A: 1 3/7 B: 2 1/2 C: 5 5/7 D: 17 1/2

Answer:

C. $AB = 5\frac{5}{7}$

Step-by-step explanation:

When two polygons are considered similar, the ratio of their corresponding sides would also be equal.

Since ∆ABC and ∆ADE are similar, $\frac{AE}{AC} = \frac{AD}{AB}$

$\frac{7}{4} = \frac{10}{AB}$

Cross multiply

$7*AB = 10*4$

$7*AB = 40$

Divide both sides by 7 to find AB

$\frac{7*AB}{7} = \frac{40}{7}$

$AB = \frac{40}{7}$

$AB = 5\frac{5}{7}$

The Fahrenheit and Celsius scales are related by the equation F=9/5C+32. What temperature is equal to a body temperature of 98.6

____ [38]

$\textbf{Substitute\ in\ the\ equation}$

$\displaystyle 98.6 = \frac{9C}{5} +32$

$\textbf{Solve\ for\ }C$

$\displaystyle 66.6 = \frac{9C}{5}$

$333=9C$

$\large C=\textbf{37 \textdegree C}$

can someone please tell me how to do 2x=3y and 4x-3y=12 using substitution to solve the system of equations.

maw [93]

Answer:

Step-by-step explanation:

you divide the two to the y, which is x=3/2y

then, you simplify the second equation to y, which is -3y= -4x+12

then, you substitute the x=3/2y into the second equation,

-3y = -6+12

-3y = 6

y = -2

Substitute the y into the first equation, x= 3/2y,

x = -3

Solve for x. x2 + x - 6 = 0 A. -2, -3 B. -2, 3 C. 2, -3 D. 2, 3

stiv31 [10]

Factor x^2 + x - 6

(x - 2)(x + 3) = 0

Solve for x

Ask yourself; When will (x - 2)(x + 3) equal zero?

When x - 2 = 0 or x + 3 = 0

Then solve for each of the two equations above

x = 2, -3

Answer: C. 2, -3
