GUYS I NEED HELP URGENTLY!!!!!
Answer:
y = 4x-3
Step-by-step explanation:
First we need to determine the slope
Using two points on the line (0,-3) (1,1)
Using the slope formula
m = (y2-y1) /(x2-x1)
= (1- -3)/(1-0)
(1+3)/ (1-0)
4
We know the y intercept, -3
y = mx+b where m is the slope and b is the y intercept
y = 4x-3
the polynomial p(x)=1−2x2−3x3+4x has what order?
a. 4
b. 2
c. 3
d. 1
Answer:
3
Step-by-step explanation:
Given the polynomial : p(x)=1−2x2−3x3+4x
Rearranging : p(x) = -3x³ - 2x² + 4x + 1
Looking at the polynomial Given, we can see that it is a univariate polynomial, that is it has only one variable which is x. Thus for polynomials of this sort, the order of the polynomial is the highest exponent occurring in the polynomial equation. Therefore, the order of the polynomial above is 3, because the highest power of the function is 3.
This means that those with 4 as their highest exponent are of order 4 and those with highest exponent as 2 are of order 2.
1. Estimate the area of the irregular shape. Explain your method and show your work.
Answer:
31 square units
Step-by-step explanation:
See the picture below.
Each full or almost full square was counted first. There are 24 of them.
Then parts of squares of counted together to add to 1 square. They are color coded in the figure below. After adding them all up, the total was 31.
The area of the irregular shape is,
⇒ 27.5 square units
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
The irregular shape is very similar to a trapezium with coordinates are,
(-3,3), (2, 2), (2, -2) and (-3, -4).
Now, We know that;
Area of a trapezium is,
⇒ [(a + b)/2] × h
where, a and b refer to the two parallel sides and h is the distance between them.
Hence, From the above coordinates:
a = 7 length units,
b = 4 length units and
h = 5 length units.
Therefore, We get;
The approximate area = [(7 + 4)/2]5
= 27.5 square units
Thus, The area of the irregular shape is,
⇒ 27.5 square units

Answer:
x=5
Step-by-step explanation:
The sides have to be equal length
3x+4 = 5x-6
Subtract 3x from each side
3x+4-3x = 5x-6-3x
4 = 2x-6
Add 6 to each side
4+6 = 2x-6+6

Consider the following 8 numbers, where one labelled
x
is unknown.
12, 46, 31,
x
, 49, 24, 41, 14
Given that the range of the numbers is 63,
work out 2 values of
x
.
Put the data set in order:
12, 14, 24, 31, 41, 46, 49
In order to find a value of x using the range, x has to be on either end of the data set. Meaning:
x, 12, 14, 24, 31, 41, 46, 49 or 12, 14, 24, 31, 41, 46, 49, x
Since the range is the highest value minus the lower value, you can set two equations for x:
x - 12 = 63
x = 75
49 - x = 63
x = -14
Thus, x = 75, -14
Two values of x are -14 & 75
What is range of numbers ?The difference between highest and lowest numbers of the set of numbers is called the range of numbers.
What are the values of x ?The given values are 12, 46, 31, 49, 24, 41, 14
Arranging all the values in ascending order we get,
12, 14, 24, 31, 41, 46, 49
If x will be included, then x is in the 1st position or in the last position.
Then the values are x, 12, 14, 24, 31, 41, 46, 49 or 12, 14, 24, 31, 41, 46, 49, x
The range of the number is 63
So, we get two equations from it.
1 ) 49-x = 63
2 ) x-12 = 63
Solving eq. (1) we get, x = 49-63 = -14
Solving eq. (2) we get, x = 63+12 = 75
So the values of x are -14 & 75

Answer:
See attachment for graph
Step-by-step explanation:
See comment for correct question
Given
[tex]y = \log_bx[/tex]
Required
The corresponding points on [tex]y =b^x[/tex]
On the graph, we have:
[tex](x_1,y_1) \to (1,0)[/tex]
[tex](x_2,y_2) \to (2,1)[/tex]
[tex](x_3,y_3) \to (4,2)[/tex]
[tex](x_4,y_4) \to (8,3)[/tex]
[tex](x_5,y_5) \to (16,4)[/tex]
First, we solve for b in [tex]y = \log_bx[/tex]
Using laws of logarithm, the equivalent of the above is:
[tex]x = b^y[/tex]
[tex](x_2,y_2) \to (2,1)[/tex] implies that:
[tex]2 = b^1[/tex]
[tex]2 = b[/tex]
Rewrite as:
[tex]b =2[/tex]
So, the equation [tex]y =b^x[/tex] becomes:
[tex]y = 2^x[/tex]
Using the same values of x, we have:
[tex](x_1,y_1) = (1,2)[/tex]
[tex](x_2,y_2) = (2,4)[/tex]
[tex](x_3,y_3) = (4,16)[/tex]
[tex](x_4,y_4) = (8,256)[/tex]
[tex](x_5,y_5) = (16,65536)[/tex]

The points (1,2), (2,4), and (4,16) are plotted on the graph attached below and this can be determined by using the given data.
Given :
Logarithmic Function -- [tex]\rm y = log_b(x)[/tex] --- (1)
The following steps can be used in order to determine the corresponding points that must be on the graph [tex]\rm x = b^y[/tex]:
Step 1 - Now, substitute the value of x and y that is (2,1) in the expression [tex]\rm x = b^y[/tex].
[tex]\rm 2 = b^1[/tex]
b = 2
Step 2 - Now, substitute the value of b in the equation [tex]\rm y=b^x[/tex].

Select the two binomials that are factors of this trinomial.
x^2-x-12
A. X+6
B. X-4
C. X-6
D. x + 3
Answer:
B and D
Step-by-step explanation:
Given
x² - x - 12
Consider the factors of the constant term (- 12) which sum to give the coefficient of the x- term (- 1)
The factors are - 4 and + 3 , since
- 4 × 3 = - 12 and - 4 + 3 = - 1 , then
x² - x - 12 = (x - 4)(x + 3) ← in factored form
Answer:
B and D
Step-by-step explanation:
If you call s=-1 the coefficient of x and p=-12 the constant term, you must find two numbers whose sum is s and product is p.
In this case the two numbers are -4 and +3 in fact:
(-4)+(+3)=-1=s
(-4)*(+3)=-12=p
The polynomial can therefore be written as
(x-4)(x+3)
If you want to check this result, just multiply and get:
(x-4)(x+3)=x^2+3x-4x-12=x^2-x-12

Answer:
Area of label = 100 inch² (Approx.)
Step-by-step explanation:
Given:
Height of label = 8 inches
Diameter of label = 4 inches
Find:
Area of label
Computation:
Design of label = Rectangle
So,
Width of label = 2πr
Width of label = 2(3.14)(4/2)
Width of label = 2(3.14)(2)
Width of label = 12.56 inches
Area of label = Height of label x Width of label
Area of label = 12.56 x 8
Area of label = 100.48
Area of label = 100 inch² (Approx.)

What is the function rule for the line?
Answer:
y =2/3x -2
Step-by-step explanation:
The y intercept is -2
The slope is
m = (y2-y1)/ (x2-x1)
Using the points (0,-2) and (3,0)
m = ( 0 - -2)/(3 -0)
= (0+2)/(3-0)
= 2/3
The slope intercept form is
y = mx+b where m is the slope and b is the y intercept
y =2/3x -2
if (1/4)^(x+y) = 256 and log₄(x-y) = 3, what are the exact values of x and y
Answer:
x = 30 and y = -34
Step-by-step explanation:
Given the following functions
(1/4)^(x+y) = 256... 1
log₄(x-y) = 3.... 2
From equation 2;
x-y = 4³
x-y = 64
x = 64 + y ... 3
Substitutw 3 into 1
From 1:
(1/4)^(x+y) = 256
(1/4)^(64+y+y) = 256
(1/4)^(64+2y) = 256
Take log₄ of both sides
64+2y log₄ (1/4) = log₄256
-(64+2y) = 4log₄4
-(64+2y) = 4
64+2y = -4
2y = -4 - 64
2y = -68
y = -34
Since
x = 64 + y .
x = 64 - 34
x = 30
Hence x = 30 and y = -34

Answer:
29.87 metros cuadrados
Step-by-step explanation:
Dados los siguientes datos;
Área de tierra = 35.72 yardas cuadradas
Para encontrar el área del terreno en metros cuadrados;
Para hacer esto, tendríamos que convertir el valor en yardas cuadradas a metros cuadrados.
Conversión:
1 yarda cuadrada = 0.8361 metros cuadrados
35.72 yardas cuadradas = X metros cuadrados
Multiplicación cruzada, tenemos;
X = 35.72 * 0.8361
X = 29.87 metros cuadrados
