240 people are going to a charity event 3/5 of the guests have ordered chicken for their meals of the remaining guests 12.5% hav
Yuri [45]

Answer: 84 people

Step-by-step explanation:

From the question, 240 people are going to a charity event and 3/5 of the guests have ordered chicken for their meals. This means (3/5 × 240) = 144 people ordered chicken. Since 144 people have ordered, the number of remain people left will be:

= 240 - 144

= 96 people.

Out of the remaining guests which is 96, 12.5% have ordered gluten free meals. This means (12.5% × 96) = 12 ordered gluten free meals.

The people who haven't ordered their meals yet will be:

= 96 - 12

= 84 people.

Which expression can be used to find the sum of the polynomials? (9 – 3x2) (–8x2 4x 5)
SIZIF [17.4K]

For this case we have:

Polynomial 1: P (x) = 9-3x ^ 2

Polynomial 2: Q (x) = - 8x ^ 2 + 4x + 5

Sorting the polynomials:

Polynomial 1: P (x) = - 3x ^ 2 + 9

Polynomial 2: Q (x) = - 8x ^ 2 + 4x + 5

Adding term to term (similar) we have:

P (x) + Q (x) = (- 3-8) x ^ 2 + (0 + 4) x + (9 + 5)\\P (x) + Q (x) = - 11x ^ 2 + 4x + 14

Answer:

A (x) = P (x) + Q (x) = - 11x ^ 2 + 4x + 14

Graph the function f(x) = x3 – 3x – 2. Based on the graph, which value for x is a double root of this function?
Lana71 [14]

Answer:

The value of x = - 1 and 2 double root of this function

Step-by-step explanation:

we need to find the value of x which double root of f(x)=x^{3} -3x-2

If we replace x with -2 then

f(-2)=(-2)^{3} -3(-2)-2 = -8+6-2 =-4

If we replace x with -1 then

f(-1)=(-1)^{3} -3(-1)-2 = -1+3-2 =0

If we replace x with 1 then

f(1)=(1)^{3} -3(1)-2 = 1-3-2 =-4

If we replace x with 2 then

f(2)=(2)^{3} -3(2)-2 = 8-6-2 =0

Hence, the value of x = - 1 and 2 double root of this function

Sketch a plane containing points E,D, and B; where E and B are collinear with A , and D is a vertex where CD and FD meet.
Irina18 [472]

Solution:

we have been asked to sketch a plane containing points E, D and B.

where E and B are collinear with A. It mean all thses three points will fall on a straight line. Also D is a vertex where CD and FD meets.

The sketch has been attched below.

Here as you can see three points are in a staright line and we have another one in whuch two vectors CD and FD are meeting at the vertex D.
