6c^2 - 5d + 8 when c =5 and d=4

Answers

Answer 1

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.

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

Answers

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

Find the measure of x.

Answers

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

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]

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

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
