Answer:

50°

Step-by-step explanation:

The internal angles on a quadrilateral sum to 360.

So x+10+2x+x+3x=360

7x+10=360

7x=350

x=50

What are the x intercepts of the graph of this function? Y=6*2+10x - 4
Damm [24]
X intercpe is when y=0

0=6x^2+10x-4
factor
0=2(3x^2+5x-2)
assume
0=3x^2+5x-2
0=(x+2)(3x-1)
set to zero
x+2=0
x=-2
3x-1=0
x=1/3

x intercepts are -2 and 1/3

Which equation represents the area of the triangle? A) A = 1 2 (AC)(AB)(sin A) B) A = 1 2 (AC)(BC)(sin A) C) A = 1 2 (BC)(BD)(si
Juliette [100K]

Answer:

The correct option is A.

Step-by-step explanation:

Let the vertices of the triangle be ABC.

Draw a perpendicular on AC from B. The height of triangle is represented by the altitude from B.

\sin A=\frac{BD}{AB}

AB\sin A=BD

Area of the triangle is

A=\frac{1}{2}\times base\times height

A=\frac{1}{2}\times (AC)\times (BD)

A=\frac{1}{2}\times (AC)\times (AB)\sin A

A=\frac{1}{2}(AC)(AB)\sin A

Therefore option A is correct.

krok68 [10]

Answer: $ 436.81

Step-by-step explanation:

Given: Hourly rate for Peggy= $7.50

Also, she receives 9% of the gratuities earned by all the staff.

Total hours she worked = 35 hours

Total gratuities = $1936.80

Gross pay = (Hourly rate ) x (Number of hours worked)+ 9% of (Total gratuities )

= $ [(7.50 ×35)+(0.09 ×1936.80)]

= $ (262.5  +174.31)

= $ 436.81

Hence, her gross pay = $436.81

If b>1 in a function of the form f(x) = ab^x, is the function an example of exponential growth or exponential decay?
alex41 [277]

Answer:

It's exponential growth.

Step-by-step explanation:

b/c any value of b that's greater than 1 is an exponential growth function, and anything that's 0<b<1 or if b<0, the function would be an exponential decay.
