Answer:
138
Step-by-step explanation:
First, we can simply replace the variables with their numerical values.
Whenever you see a number with a letter (variable) in front of it, this means to multiply.
c=5 and d=4
6 × 5^2 - 5 × 4 + 8
Since there are multiple operations in this expression, we must use PEMDAS.
ParenthesisExponentiation (exponents)Multiplication/Division (Solve whichever comes first)Addition/Subtraction (Solve whichever comes first)--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Now, we can apply the operations.
There are no parenthesis.
In this expression, exponents are present.
6 × 5^2 - 5 × 4 + 8
6 × 25 - 5 × 4 + 8
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
There is multiplication.
6 × 25 - 5 × 4 + 8
150 - 5 × 4 + 8
150 - 20 + 8
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
There is subtraction.
150 - 20 + 8
130 + 8
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
There is addition.
130 + 8
158
Therefore, 6 × 5^2 - 5 × 4 + 8 = 138.
Guys pls help me!!!!!
Answer:
2) y = 0.5^x
Step-by-step explanation:
Plug in x coordinates to see which equation makes up the graph. We can see that the y values lower even after using positive numbers so this eliminates the possibility of 1) as that would make the y values increase. Starting with coordinates (-1, 2), let's plug these into 2):
y = 0.5^x
2 = 0.5^-1
2 = 2
Correct
Use another pair of coordinates to see if it still works:
(-2, 4)
4 = 0.5^-2
4 = 4
It does!
Check the other equations just to make sure this is the only option:
2 = 5^(- - 1)
Negative + Negative = Positive
2 = 5^1
2 = 5
Incorrect.
2 = 0.5^(- - 1)
2 = 0.5^1
2 = 0.5
Incorrect.
This means our first solution is the only solution.

Find the value of x and show all steps please
Answer:
x = 88
Step-by-step explanation:
Opposite angles in a quadrilateral inscribed in a circle are supplementary
Supplementary meaning that the sum of the two angle measures is 180
The opposite angle of "x" is ∠B which has a measure of 92°
Thus, 92 + x = 180
180 - 92 = 88
Hence, x = 88
Write a congruence statement for the pair of triangles
Evaluate the expression.

DONE
Find the measure of x.
Answer:
C
Step-by-step explanation:
Since the triangles are congruent then corresponding angles are congruent
x is the angle between line with 3 strokes and 2 strokes
The corresponding angle is therefore ∠ C
∠ C = 180° - (63 + 29)° = 180° - 92° = 88°
Then x = 88 → C

Find the sixth term of the geometric sequence
9, 18, 36, ...
Answer:
This is a geometric sequence because any term divided by the previous term is a constant called the common ratio. r=36/18=18/9=2 A geometric sequence is expressed as
\begin{gathered}a_n=ar^{n-1},\text{ where a=initial term, r=common ratio, n=term number}\\ \\ a_n=9(2^{n-1})\\ \\ a_6=9(2^5)\\ \\ a_6=288\end{gathered}an=arn−1, where a=initial term, r=common ratio, n=term numberan=9(2n−1)a6=9(25)a6=288

Answer:
A. [tex]Log_p N = b \ and \ b^p = N[/tex]
Step-by-step explanation:
A. The given options are;
[tex]Log_p N = b \ and \ b^p = N[/tex]
For [tex]Log_p N = b[/tex] we have;
[tex]p^b = N[/tex]
However;
[tex]b^p = N[/tex]
Where, p ≠ b
[tex]p^b \neq b^p[/tex]
Therefore;
N ≠ N for the given pair and the pair are therefore, not equivalent
B. x = √y and [tex]x = y^{1/2}[/tex]
We note that
x = √y = [tex]y^{1/2}[/tex]
We have;
x = [tex]y^{1/2}[/tex], by transitive property
Therefore, the pair, x = √y and [tex]x = y^{1/2}[/tex] are equivalent
C. [tex]Log_b N = p \ and \ b^p = N[/tex]
From [tex]Log_b N = p[/tex], we have;
[tex]b^p = N[/tex]
Therefore, [tex]Log_b N = p \ and \ b^p = N[/tex] are equivalent pairs as [tex]b^p = N[/tex] can be obtained from [tex]Log_b N = p[/tex]
D. ㏑x = y and x = [tex]e^y[/tex]
[tex]ln \ x = ln_e \ x = y[/tex], therefore, by rules of logarithm, we have;
x = [tex]e^y[/tex]
Therefore, ㏑x = y and x = [tex]e^y[/tex] are equivalent pairs, as x = [tex]e^y[/tex] can be obtained from ln x.
Therefore;
The option which are not equivalent pair is option is [tex]Log_p N = b \ and \ b^p = N[/tex]

PLEASE HELP. urgent. What is the answer? HELP please!
From the figure, we can notice that : Surface area of the pyramid is equal to Sum of the area of the square and Sum of the areas of 4 triangles.
We know that : Area of a square is given by : Side x Side
Given : Side of the square = 3 cm
⇒ Area of the square = 3 x 3 = 9 cm²
We know that : Area of the triangle = 1/2 x Base x Height
From the figure, We can notice that, Base of each triangle = 3 cm and height of the each triangle = 3 cm
⇒ Area of one triangle = 1/2 × 3 × 3 = 4.5 cm²
Surface area of the pyramid = Surface of the square + Surface area of the 4 triangles
⇒ Surface area of the pyramid = 9 cm² + 4(4.5) cm²
⇒ Surface area of the pyramid = 9 cm² + 18 cm² = 27 cm²
Answer : Surface area of the pyramid = 27 cm²
Drag each tile to the correct box. A data set that consists of many values can be summarized using the five-number summary. Arrange these five values in order from least to greatest.
Answer:
Minimum < Q1 < Median < Q3< Maximum
Step-by-step explanation:
Given
Minimum, Median, Maximum, Q3 and Q1
See attachment for complete question
Required
Order from least to greatest
In a dataset, the range is:
[tex]Range = Maximum - Minimum[/tex]
This implies that, the minimum is the least and the maximum is the highest of the dataset
So, we have:
Minimum < < < < Maximum
The median is the middle item; So, the above becomes
Minimum < < Median < < Maximum
In a dataset, the IQR is:
[tex]IQR = Q_3 - Q_1[/tex]
This implies that:
[tex]Q_3 > Q_1[/tex]
So, we have:
Minimum < Q1 < Median < Q3< Maximum

Answer:
A. (4,2)
Step-by-step explanation:
In coordinates, the x-value appears first then the y-value. This means coordinates are set up like, (x,y). So, to solve find the coordinates whose values match one pair of values on the table. Option A has x=4 and y=2. In the last row of the table, you can see the same values with x=4 and y=2. Therefore, A is correct.

Answer:
135
Step-by-step explanation:
so we need to find the volume of the rectangle
V= L x W x H
V = [tex]2\frac{1}{4}[/tex] x [tex]\frac{3}{4}[/tex] x [tex]1\frac{1}{4}[/tex] = [tex]\frac{135}{64}[/tex]
so now we need to find the volume of the cubes
V = a^3
1/4^3 = 1/64
so:
135/64 ÷ 1/64 = 135

What is the area of the trapezoid?
Answer:
Area = 40mm
Example:
The below-solved example problem may be useful to understand how the values are being used in the mathematical formulas to find the trapezoid area.
Example Problem :
Find the area of a trapezoid having the bottom length a = 15 cm, top length b = 12 & height h = 9 cm?
Solution :
The given values
bottom length a = 15 cm
top length b = 12 cm
height h = 10 cm
Step by step calculation
formula to find area = ((a + b)/2) h
substitute the values
= ((15 + 12)/2) x 9
= 121.5 cm2
