Step-by-step explanation:

The table that corresponds to the equation y = ¹/₄(4ˣ) is; Table C

How to simplify an equation?

We are given the equation; y = ¹/₄(4ˣ)

At the input value of x = 0;

x = ¹/₄(4⁰)

x = ¹/₄

At the input value of x =  1;

y = ¹/₄(4¹)

y = 1

At the input value of x = 2;

y = ¹/₄(4²)

y = 4

At the input value of x = 3;

Thus;

y = ¹/₄(4³);

y = 16

At the input value of x = 4;

y = ¹/₄(4⁴)

y = 64

At the input value of x = 5;

y = ¹/₄(4⁵)

y = 256

Lincoln told his mother that 4 5/10
represents his height, in feet. Which decimal measurement represents Lincoln's height?

Answers

Answer:

[tex]4.5[/tex]

Step-by-step explanation:

In order to find the answer to this question you will first need to convert Lincolns height into a improper fraction and then convert the improper fraction into a decimal number.

[tex]L =4\frac{5}{10}[/tex]

Convert into improper fraction

[tex]4\frac{5}{10} =10 \times4=40+5=45=\frac{45}{10}[/tex]

Convert into decimal by dividing the numerator by the denominator:

[tex]45\div10=4.5[/tex]

[tex]L=4.5[/tex]

The price of an item yesterday was $40. Today, the price fell to $22. Find the percentage decrease.

Answers

Answer:

45%

Step-by-step explanation:

40 * .45 = 18

40-18 = 22

The percentage decrease of an item would be 45%.

What is the percentage?

The percentage is defined as a ratio expressed as a fraction of 100.

We can determine the value of the percentage decrease by the following formula,

percentage decrease = (initial value - reduced value) / initial value × 100%

As per the given question, we have

initial value = $40, and reduced value = $22

Substitute the values in the above formula, and we get

percentage decrease = (40 - 22) / 40 × 100%

percentage decrease = (18) / 40 × 100%

percentage decrease = 0.45 × 100%

Apply the multiplication operation, and we get

percentage decrease = 45%

Thus, the percentage decrease of an item would be 45%.

Answers

Answer:c

Step-by-step explanation:

The statement which is true for the given expression triangle is, 9/(x + y) = 3/x. So option c is correct.

What is similarity of triangles?

Triangles with the same shape but different sizes are said to be similar triangles. Squares with any side length and all equilateral triangles are examples of related objects. In other words, if two triangles are similar, their corresponding sides are proportionately equal and their corresponding angles are congruent. Triangle resemblance is shown here by the symbol "≈"

Given that,

One right angle triangle, ΔAEC

one segment BD which is intersecting sides AC & AE

ΔAEC has one similar triangle inside, which is ΔADB

Triangle ΔAEC and ΔADB similar,

So, we can say ΔAEC ≈ ΔADB

For the given similar triangles,

we can use angle-angle similarity property,

so, AE/AC = AD/AB

⇒ (3+6)/(x + y) = 3/x

⇒9/(x + y) = 3/x

Hence, the Statement C is correct
