Find p(-1) and p(5) for the function p(x)= 9x to the 4th power+9x to the third power- 11x to the 2nd power+12x+5
Answer:
P(-1) = -18
P(5) = 6540
Step-by-step explanation:
Given the polynomial function
P(x) = 9x⁴+9x³-11x²+12x+5
We are to find p(-1) and p(5)
P(-1) = 9(-1)⁴+9(-1)³-11(-1)²+12(-1)+5
P(-1) = 9(1)+9(-1)-11(1)-12+5
P(-1) = 9-9-11-12+5
P(-1) = -23+5
P(-1) = -18
Get p(5)
P(5) = 9(5)⁴+9(5)³-11(5)²+12(5)+5
P(5) = 9(625)+9(125)-11(25)+65
P(5) = 5625+1125-275+65
P(5) = 6540

I need help with this question, in the picture.
Answer:
34 degrees
Step-by-step explanation:
34 degrees
the angle is 90 degrees
90-56=34
======================================================
Explanation:
Refer to the diagram below. I've added the variable y as the base angles to the isosceles triangle on the left.
Recall that the angles opposite the congruent sides are the base angles. The base angles of any isosceles triangle are the same measure.
Let's solve for y
y+y+56 = 180 .... all angles in a triangle add to 180
2y+56 = 180
2y = 180-56
2y = 124
y = 124/2
y = 62
I've also added the variable z, which is adjacent to one of the y angles.
Since y and z combine to form a straight angle, this means the two angles add to 180
y+z = 180
z = 180-y
z = 180-62
z = 118
Now focus on the isosceles triangle on the right. It has angles x, x, and z = 118.
x+x+z = 180
x+x+118 = 180
2x+118 = 180
2x = 180-118
2x = 62
x = 62/2
x = 31

Answer: out of 1400 students 672 of them are males.
Step-by-step explanation:
Step 1 turn the percent into a decimal
0.52*1400= 728
728 is the number of female students
Step 2 subtract 728 from 1400
1400-728=672

Ashley’s school took a field trip. A total of 32 vehicles were needed for the trip. Some students took the bus, and some students car-pooled. There were 27 people on each bus and 3 people in each car. 408 people altogether attended the trip. How many buses and cars were needed for the trip?
Answer:
19 cars
13 buses
Step-by-step explanation:
We have a system of equations as follows
X + y = 32 -----1
3x + 27y = 408 ----2
x = car
y = bus
From equation 1
x + y = 32
x = 32 - y ---- 3
We put equation 3 into equation 2
3(32-y) + 27y = 408
96y -3y + 27y = 408
96 + 24y = 408
24y = 408 - 96
24y = 312
Divide through by 24 to get the value of y
Y = 312/24
Y = 13
We put the value of y in equation 3
x = 32 - 13
x = 19
So 19 cars would be needed for the trip and also 13 buses would also be needed

yoko made $231 for 11 hours of work. At the same rate, how much would she make for 8 hours of work.
Answer:
Step-by-step explanation:
If Yoko made 231 dollars in 11 hours, it means that she makes
231/11=21 dollars per hour
in 8 hours
8*21=168 dollars in 8 hours
Answer:
168
Step-by-step explanation:
We need to find how much money she makes in one hour. Then multiply that by 8.
231 ÷ 11 = 21
21 × 8 = 168

The length and width of a garden are in a ratio of 10:8. The perimeter of the garden is 324 feet. What is the length and width?
Answer:
length= 90feet
width =72 feet
Step-by-step explanation:
perimeter=2(L+W)
324=2(L+W)
324/2=L+W
162=L+W( at a ratio of 10:8)
length=10/18 * 162=90
width=8/18*162=72
2(90+72)=324

Katy organised a wedding. Guests had to choose their meal from pasta , chicken or beef . 1/3 of the guests chose pasta . 5/12 of the guests chose chicken . 24 of the guests chose beef. How many guests were at the wedding ?
please help i’ll give brainliest
Answer:
There were 96 guests at the wedding.
Step-by-step explanation:
Let,
x be the total number of guests at the wedding.
People who chose pasta = 1/3 of the guests = [tex]\frac{1}{3}x[/tex]
People who chose chicken = [tex]\frac{5}{12}x[/tex]
People who chose beef = 24
Now,
[tex]\frac{1}{3}x+\frac{5}{12}x+24=x\\\\\frac{4x+5x+288}{12}=x\\9x+288 = 12x\\288=12x-9x\\288=3x\\3x=288[/tex]
Dividing both sides by 3
[tex]\frac{3x}{3}=\frac{288}{3}\\x=96[/tex]
Hence,
There were 96 guests at the wedding.

Which of the following are solutions to the inequality below? Select all that apply.
35 ≤ 4 + 9d
A. D=11
B. D=8
C. D=10
D. D=9
Answer:
d ≤ 3.45
Step-by-step explanation:
The given inequality is :
35 ≤ 4 + 9d
We need to find the solution of the above inequality.
Subtract 4 from both sides of the inequality.
35-4 ≤ 4 + 9d -4
31 ≤ 9d
d ≤ 3.45
Out of all options, none is correct as the value of d is greater than equal to 3.45.

In accordance with functional theory, definition of functions and kinds of functions, the function is not injective but surjective. (Correct choice: C)
Does represent the picture of the function an injective or surjective function?
In accordance with functional theory, functions are relations in which each element of the domain is related to only one element of the range. There are three kinds of functions: (i) Injective - Each domain element is related to one distinct element of the range, (ii) Surjective - There are at least two domain elements that are related to an element of the range, (iii) Bijective - The function is both injective and surjective.
Based on all these information, we conclude that the given function has at least two values of the x-axis (domain) related to one value of the y-axis (range). In a nutshell, the function is not injective but surjective. (Correct choice: C)
