Answer:

Hope I Help!

Step-by-step explanation:

−2x+3−4x2+11−15x+2x2−15

=−2x+3+−4x2+11+−15x+2x2+−15

Combine Like Terms:

=−2x+3+−4x2+11+−15x+2x2+−15

=(−4x2+2x2)+(−2x+−15x)+(3+11+−15)

=−2x2+−17x+−1

An artist wishes to make a sign in the shape of an isosceles triangle as shown. find the area
Katarina [22]

Answer:

Step-by-step explanation:

Drop an angle bisector from angle C until it intersects AB. Because of the symmetry of the triangles created, you will form two small right angle congruent triangles. Call the point of intersection with AB = D. In other words the bisector of <C is CD.

CB = AC                          Isosceles triangle

CD / CB = Sin(38.5)        

  CD=?

  CB = 35

CD / 35 = Sin(38.5)      Multiply both sides by 35

CD = 35 * sin(38.5)

CD = 21.79

BD/CB  =  Cos(38.5)

BD = CB* Cos(38.5)

BD = 35 * Cos (38.5)

BD = 27.39

Area = CD * BA/2

BA/2 = DB

Area = CD * BD

Area = 21.79 * 27.39

Area = 596.9

A pizza restaurant markets 3 versions of its Crazy Combo: Combo 1 contains
worty [1.4K]

Answer:

Step-by-step explanation:

combo 1 : 3 cheese and 1 pepperoni

combo 2: 2 cheese and 2 pepperoni

combo 3: 1 cheese and 3 pepperoni

he chooses :

5 combo 1's : so thats (5 * 3) = 15 cheese, (5 * 1) = 5 pepperoni

2 combo 2's.....(2*2) = 4 cheese and (2 * 2) = 4 pepperoni

3 combo 3's....3(3 * 1) = 3 cheese and (3 * 3) = 9 pepperoni

added = a total of 22 cheese and 18 pepperoni....thats 40 pizzas

so the probability that he will randomly pick a pepperoni is 18/40 which reduces to 9/20

the probability that he will pick a cheese is 22/40 which reduces to 11/20

so ur answer is D. <===

Answer:

x = \frac{(a+1)f^3}{2e}

Step-by-step explanation:

\frac{a + 1}{2x} = \frac{e}{f^3}\\~\\\\a+1 = \frac{2ex}{f^3}\\~\\\frac{a + 1}{2e} = \frac{x}{f^3}\\~\\x = \frac{(a+1)f^3}{2e}
