If you have the function f(x) = 5^x - 5 then find the value of f(t)

Answer:

The figure is reflected over y = -2

Step-by-step explanation:

If you draw a horizontal line through y = -2, so will see that every point is the same distance from y = -2 but in the opposite direction.  For example, Point w is 3 units above  y= -2 and w' is three units below y = -2. That is true for every point on original to the image.

32 ounces of pure silver were used to make the silver alloy.

Here, we are given that a silversmith combines pure silver that costs $34.48 per ounce with 51 oz of a silver alloy that cost $25.35 per ounce.

Let the amount of pure silver = x oz

Cost of pure silver = $34.48 per ounce

Thus, total cost of pure silver = $34.48x

Similarly, amount of silver alloy = 51 oz

Cost of silver alloy = $25.35 per ounce

Thus, total cost of silver alloy = 25.35 x 51 = $1292.85

Now, the total weight of the new silver allow formed = (x + 51) Oz

and the cost of this new allow = $28.87 per ounce

Thus, the total weight of the new alloy = $28.87 (x + 51)

Hence, we can form the following equation-

$34.48x + $1292.85 = $28.87 (x + 51)

34.48x + 1292.85 = 28.87x + 1472.37

34.48x - 28.87x = 1472.37- 1292.85

5.61x = 179.52

x = 179.52/ 5.61

x= 32

Hence, 32 ounces of pure silver were used to make the silver alloy.

The position of town B in cartesian plane is 6.4 cm in 1st quadrant at an angle of 70°.

As per the question statement, we are given that a diagram which shows the position of town A and the scale of 1 cm representing 10 km.

Town B is 64 km from town A on a bearing of 070°. We are supposed to tell the position of town B.

Let's assume that town A lies at origin in cartesian plane and as 1 cm represents 10 km therefore,

[tex]1cm = 10 km\\1 km = 0.1 cm\\64 km = 64*0.1=6.4 cm[/tex]

The town B is 6.4 cm from the origin and as the angle is given as  70° so the position of town B is in 1st quadrant.

Therefore the position of town B is 6.4 cm in 1st quadrant at an angle of 70° when town A lies at origin in the cartesian plane.

Answer:

True

Step-by-step explanation:

We use definitions to help us in this problem. The definition of an integer is a whole number that is not a fraction or has any fractional value. This definition includes all whole numbers, so we know that all whole numbers can be classified as integers. That's one condition done. The definition of a rational number is a number that can be written as a fraction. All whole numbers can be written as a fraction (i.e. 12/1, -3/1, 10000/1). This means that all whole numbers are also rational numbers, giving us our final answer of True.

Answer:

Step-by-step explanation:

The square root of one hundred forty is less than one hundred five ninths. So, option D is correct.

According to this question we have to compare the square roots of both numbers One Hundred Forty and One Hundred Five Ninths. So, we have to calculate their square roots.

The square root of One hundred Forty: √140

The square root of One hundred Forty:  11.832

The square root of One Hundred Five Ninths: √159

The square root of One Hundred Five Ninths: 12.609

Comparing both of their square roots we can clearly see that :

           (11.832) < (12.609)

The square root of 140 < Square root of 159

Hence, option D is correct. The square root of 140 is less than 159.

Answer:

  A.  A(l) = l² -6l

Step-by-step explanation:

You want a quadratic function for the area of a rectangle whose width is 6 feet less than its length.

Let l (ell) represent the length of the rectangle in feet. Then the width will be 6 feet less, or (l -6). The area is the product of length and width:

  A = LW

  A(l) = l(l -6)

  A(l) = l² -6l . . . . . . use the distributive property to eliminate parentheses

Answer:

Width = 15 ft

Step-by-step explanation:

Given formula,

→ A = L × W

Let us assume that,

→ Length = 4x

→ Width = x

→ Area = 900 ft²

Then the value of width will be,

→ A = L × W

→ 900 = 4x × x

→ 4x² = 900

→ x² = 900/4

→ x = √225

→ [ x = 15 ft ]

Hence, the value of width is 15 ft.

We can use the concept of unitary method to solve the question.The weight of 6 cubic feet of water is 0.19 Ton.

Unitary method helps us in finding the solution to seemingly complicated problems, here we have been given the amount of water that one cubic foot can hold, first we need to find out how much water 6 cubic feet can hold.

1 cubic foot hols 7.48 gallons of water

6 cubic feet holds 7.48x6 gallons of water=44.88 gallons

Next we know how much 1 gallon of water weighs in pounds,we need to find out how much 44.88 gallons of water weigh in pounds first and then convert it to tons.

1 gallon weighs 8.33 pounds

44.88 gallons weighs 8.33x44.88=373.8504 pounds

1 Ton=2000 pounds

373.8504 pounds=[tex]\frac{373.8504}{2000}[/tex]=0.1869 Ton≈0.19 Ton

Thus we can see that 6 cubic feet of water weighs 0.19 Ton, we used unitary method step by step to reach this result.

To address the issue, we must understand what the converse of a statement implies. The statement's opposite is true if a=bc and a/b=c.

By switching the condition and the result, a conditional statement can be made into its opposite. The converse of a statement is q—->p if the statement is p—->q. In the provided question, the condition is stated as a/b=c, and the answer is a=bc if the condition holds.

We must create the result, the condition, and the condition will be the new result in order to discover the opposite of this assertion. As a result, a=bc will be the condition for converse, and a/b=c will be the outcome if the condition is satisfied.

The statement that best interprets the quotient is "there are 6( 1/4 ) two  - third in 4( 1/6 )".

In mathematics, the sum obtained by diluting two numbers is known as a quotient. The term "quotient" is used frequently in mathematics and is sometimes known as the integer portion of a division, a fraction, or a ratio.

Any integer may be used as the larger number in a fraction, which is a number that represents a percentage of the larger number. It is shaped like a denominator and a numerator.

For step 1:

The shaded part is:

4 + 1/6 = 4(1/6) = 25/6

Now, dividing the shaded part by the unshaded part,

( 25/6 ) / ( 2/3 ) = ( 25/6 ) × ( 3/2 )

( 25/6 ) / ( 2/3 ) = 25/4

( 25/6 ) / ( 2/3 ) = 6( 1/4 )

Here we have an irregular figure that can be decomposed into 3 simpler figures, these are:

Remember that the area of a rectangle is the product between the two dimensions, so the areas of these 3 rectangles are:

a = 6in*8in = 48in^2

a' = 10in*4in = 40in^2

a'' = 5in*4in = 20in^2

Now, we are also given that to make the correct shade, Shannon makes 12 quarts of blue paint with 8 quarts of red paint.

Here the ratio becomes:

the change between each line is 105, so we start to add and then you get the resul

The value of A in the number line is the in-between of 225 and 645 so it is 435.

In mathematics, a number line is a straight line containing numbers arranged at equal segments or periods throughout its duration.

In another word, a number line is basically a line in which infinite numbers have been written in ascending order or increasing order.

A horizontal number line is the most common representation and can be extended infinitely in any direction.

Given the number line,

Now if we count the interval of A between 225 and 645 it is 2(same).

So A must be between 225 and 645.

So,

225 - A = A - 645

2A = 870

A = 435

The polynomial function is V(x) = x^3 - 7x^2 + 10x and domain of x is (5,6]

Here we are given that the length of the box is x

Also, the width of the box should be 5 feet shorter than the length

Thus, width = x - 5

and the height should be 3 feet longer than the width

Thus, height = x - 5 + 3

= x - 2

Now the volume of the box = length × width × height

Volume = x (x-5) (x-2)

V(x) = (x^2 - 5x) (x-2)

V(x) = x^3 - 2x^2 - 5x^2 + 10x

V(x) = x^3 - 7x^2 + 10x

Now, looking at the options, we see that option C is eliminated.

Now, let us look at the domain of x

Since width cannot be negative (x-5) > 0

⇒ x > 5

Now in option A domain is (0, 6], but x cannot take values from (0,5). Thus, option A is eliminated.
