Given p(x)=2x^3-3x-5 what is the value of p (-2)
Answer:
The value of p(x) at -2 is:
[tex]p(-2) = -15[/tex]
Step-by-step explanation:
Given polynomials is:
[tex]p(x) = 2x^3-3x-5[/tex]
We have to find p(-2)
This means that we have to find the value of the polynomial at -2. Finding value of a polynomial at a certain number is done by putting the number in the polynomial in place of variable. So putting x = -2
[tex]p(-2) = 2(-2)^3-3(-2)-5\\= 2(-8)+6-5\\= -16+1\\=-15[/tex]
Hence,
The value of p(x) at -2 is:
[tex]p(-2) = -15[/tex]

a line passes through the points 1 , -6 and 4,3 what is the Y intercept of this line
Answer:
y-intercept = -13
Step-by-step explanation:
So you have to put it in slope-intercept form to solve.
slope is 4 so you plug in the one of the coordinate points in for x and y in the equation to find b.
Write the equation of the line that goes through (-2, 0) and (4,3).

If the hot air balloon rises at the same rate each second, what is the hot air balloon’s rate per second?
200
feet per second
4
feet per second
4 feet per second
−4
feet per second
negative 4 feet per second
−200
feet per second
Answer:
4 ft per second
Step-by-step explanation:
We are given that it takes 50 seconds to go 200 feet
in order to find the ft/second, we divide by 50
50/50=1
200/50=4
so 4 ft/ 1 second

No estudo da circunferência é muito importante diferenciar diâmetro e raio, muito erros são cometidos pela troca desses conceitos e consequentemente a troca de seus valores. A medida do comprimento de uma circunferência é determinada pela fórmula C = 2 π. R , ou seja comprimento da circunferência é igual ao dobro do valor do π multiplicado pelo valor do raio dessa circunferência. Calcule qual a medida em cm de uma circunferência: a) cujo diâmetro mede 10 cm. b) cujo raio mede 12 cm. c) cujo diâmetro mede 2 cm. d) cujo raio mede 5 cm.
Explicação passo a passo:
A circunferência de um círculo é expressa como mostrado;
C = 2πR
R é o raio
Em termos de diâmetro;
C = πD
D é o diâmetro
a) Se o diâmetro for 10cm
Circunferência C = π (10)
C = 10 (3,14)
C = 31,4cm
b) Se o raio for 12cm
C = 2πR
C = 2π (12)
C = 24π
C = 24 (3,14)
C = 74,36cm
c) Se o diâmetro for 2cm
Circunferência C = π (2)
C = 2 (3,14)
C = 6,28cm
d) Se o raio for 5cm
C = 2πR
C = 2π (5)
C = 10π
C = 10 (3,14)
C = 31,4cm

Is every relation also a function? Explain
Answer:
no
Step-by-step explanation:
they are not
Answer:
Step-by-step explanation:
In fact, every function is a relation. However, not every relation is a function. In a function, there cannot be two lists that disagree on only the last element. This would be tantamount to the function having two values for one combination of arguments.

Select the section(s) of the graph where the function is decreasing.
1. blue line
2. red line
3. curved blue line
4. green line
can be more than one
The graph where the function is decreasing is represented by, the blue line, red line and the green line.
What is decreasing function?"If the value of the function f(x) is decreasing on increasing the value of x, then the function is called as decreasing function."
For given situation,
we have been given a piecewise function and its graph.
From the graph of a function,
we can observe that the function f(x) is decreasing for x < -3 , -3 ≤ x ≤ 0, and x > 0
This is represented by, the blue line, red line and the green line
Therefore, the correct options are 1, 2, 4.

is this correct? ILL MARK YOU BRAINIEST
Answer:
yes
Step-by-step explanation:
This is correct.
Since every operation in this is multiplication, you can remove the parentheses. This is the associative property of multiplication. Now you can group the exponents and the normal factors together.

Make x the subject of the formula
X – 7r = bc
Answer:
x = bc + 7r
General Formulas and Concepts:
Pre-Algebra
Equality PropertiesStep-by-step explanation:
Step 1: Define equation
x - 7r = bc
Step 2: Solve for x
Add 7r to both sides: x = bc + 7rState whether the relation is a function: {(1,2), (2,4),(-3,-6), (0,0)). Then
explain why.
Answer:
[tex]\boxed {\boxed {\sf Yes}}[/tex]
Step-by-step explanation:
According to the definition of a function, each input must have one output.
The input is x and the output is y. Basically, for every x there can only be one y.
The relation given is:
{ (1,2) , (2,4), (-3,-6), (0,0)}
To check if it's a function, make sure each x only appears once.
The x is the first number in a point.
We see that each x (1,2,-3,0) is only listed once, so this must be a function.
Another way to check is by graphing the points and using the Vertical Line Test.
If a vertical line is drawn and crosses the function more than once at any given part of the line, it isn't a function.
The points pass the vertical line test, so this is a function.
Tyler ate x fruit snacks, and Han ate 34 less than that. Write an expression for the number of fruit snacks Han ate.
Answer:
x = -3/4
Step-by-step explanation:
Because you have the variable x and you do not know the number of fruit snacks he ate and you need to have the same variables to properly find the answer.

9 t-shirts and a hat costs £93.00
4 t-shirts and a hat costs £43.00.
How much does a t-shirt cost?
How much does a hat cost?
Answer:
A t-shirt costs 10.00 pounds and a hat costs 3.00 pounds.
Step-by-step explanation:
x is a t-shirt
y is a hat
9x + y = 93.00
4x + y = 43.00
(9x + y) - (4x + y) = 93.00 - 43.00
9x + y - 4x - y = 50.00
5x = 50.00
x = 50.00/5
x = 10.00 [a t-shirt costs 10.00]
4x + y = 43.00
4×10.00 + y = 43.00
40.00 + y = 43.00
y = 43.00 - 40.00
y = 3.00 [a hat costs 3.00]
