Answer:

Yes

Step-by-step explanation:

Every x and y coordinate is different. The y-coordinates don't have the same x-coordinate, so the function passes the vertical line test. This function is called a discrete function since it's made up of individual points, not a line or curve.

Answer:

yes

The amount of snowfall in February 2015 was 36.4 inches and the amount of snowfall in February 2020 was 17.9 inches

From the question, we are to determine the amount of snowfall in February 2015 and in February 2020

Let the amount of snowfall in February 2015 be x

and the amount of snowfall in February 2020 by y

From the given information,

"The snowfall in February 2015 was 0.6 inch more than twice the snowfall in February 2020"

That is,

x = 0.6 + 2y

Also, from the information

"The snowfall in February 2015 was also 8.35 inches fewer than 2.5 times the snowfall in February 2020"

x = 2.5y - 8.35

Now,

Solve the system of equations simultaneously

x = 0.6 + 2y             -------- (1)

x = 2.5y - 8.35        -------- (2)

Equate equations (1) and (2)

0.6 + 2y = 2.5y - 8.35

0.6 + 8.35 = 2.5y - 2y

8.95 = 0.5y

y = 8.95/0.5

y = 17.9

Substitute the value of y into equation (1)

x = 0.6 + 2y

x = 0.6 + 2(17.9)

x = 0.6 + 35.8

x = 36.4

Hence, the amount of snowfall in February 2015 was 36.4 inches and the amount of snowfall in February 2020 was 17.9 inches

In order to cover the entire land area of United States with dollar bills, it would cost 9 × 10¹⁴ dollars.

A conversion factor can be defined as a number that is typically used to convert (change) a number in one (1) set of units to another, either by dividing or multiplying.

Generally speaking, an appropriate conversion factor to an equal value must be used when it is necessary to perform any mathematical conversion.

Conversion:

1 mile = 160934 cm

Length of contiguous land = 160934 × 3000 miles = 482,802,000 cm.

Width of contiguous land = 160934 × 1000 miles = 160,934,000 cm.

Mathematically, the area of a rectangle can be calculated by using this formula;

Area of rectangle = length × width

Area of contiguous land = 482,802,000 × 160,934,000

Area of contiguous land = 77,699,257,068,000,000 cm²

Next, we would determine the area of Alaska:

Area of Alaska = 1/5 × 77,699,257,068,000,000

Area of Alaska = 15,539,851,413,600,000 cm²

Total area = Area of Alaska + Area of contiguous land

Total area = 15,539,851,413,600,000 + 77,699,257,068,000,000

Total area = 93,239,108,481,600,000 cm²

Also, the area of a dollar bill is given by:

Area of dollar bill = 6.5 × 15.5

Area of dollar bill = 100.75 cm²

Now, we can determine the cost:

Cost = Total area/Area of dollar bill

Cost = 93,239,108,481,600,000/100.75

Cost = 9 × 10¹⁴ dollars.

The gradient-intercept form of the equation of the line which has a gradient of 5 and passes through the point (1, 11) is y = 5x + 6

Gradient intercept form Or slope incept form of a linear equation is given by

y = mx + c

where m is the gradient or slope of the equation  and c is the constant

As we are aware that the line passes through a point whose coordinates are (1, 11)

By putting the value of gradient/ slope,  x coordinate in place of x in equation and  y coordinate in place of y in equation we get

11 = 5 (1) +c

11= 5 + c

11-5 = c

6 = c

now, substituting the value of c in the Gradient/ slope intercept form

y = 5x + 6

Hence, The gradient-intercept form of the equation of the line which has a gradient of 5 and passes through the point (1, 11) is y = 5x + 6

Answer:

Equation: [tex]\sf 3x + x + 14 = 90[/tex]

m∠1 = 57°

m∠2 = 33°

Explanation:

A right angle triangle has 90° angle measure.

Here:

m∠1 + m∠2 = 90°

(a)

Substitute given values:

(3x) + (x + 14) = 90

simplify

4x = 90 - 14

evaluate

4x = 76

divide both sides by 4

x = 19

(b)

m∠1 = 3x = 3(19) = 57°

m∠2 = x + 14 = 19 + 14 = 33°

Answer:

[tex]\textsf{(a)} \quad (3x)^{\circ}+(x+14)^{\circ}=90^{\circ}[/tex]

[tex]\textsf{(b)} \quad m \angle 1=\boxed{57}\:^{\circ}[/tex]

       [tex]m \angle 2=\boxed{33}\:^{\circ}[/tex]

Step-by-step explanation:

From inspection of the given diagram:

A right angle is 90° and is represented by the ∟ symbol.

To find x, equal the sum of the angles to 90° and solve for x:

[tex]\implies m \angle 1+m\angle2=90^{\circ}[/tex]

[tex]\implies (3x)^{\circ}+(x+14)^{\circ}=90^{\circ}[/tex]

[tex]\implies 3x+x+14=90[/tex]

[tex]\implies 4x+14=90[/tex]

[tex]\implies 4x+14-14=90-14[/tex]

[tex]\implies 4x=76[/tex]

[tex]\implies 4x \div 4=76 \div 4[/tex]

[tex]\implies x=19[/tex]

To find the degree measure of each angle, substitute the found value of x into the expression for each angle.

[tex]\implies m \angle 1=(3 \cdot 19)^{\circ}=57^{\circ}[/tex]

[tex]\implies m \angle 2=(19+14)^{\circ}=33^{\circ}[/tex]

By substituting the value of x as 17 in the function R (x) = 2 x + 3.5, we get the value of R ( 17 ) as 37.5.

We are given a function:

R (x) = 2 x + 3.5

where x represents the number of feet the tide moves x minutes after 4 pm.

Now, we are asked to find R (17)

For this, we need to substitute the value of x as 17 that is we need to put x = 17 in the function that is given to us.

R ( x = 17 ) = 2 ( 17 ) + 3.5

The hexadecimal numeral system, usually known as base 16 or just "hex," is a positional numeral system used in mathematics and computing that uses the radix (base) of 16 to represent integers. Hexadecimal uses 16 different symbols as opposed to the decimal system's 10 symbols, with the most common being "0"-"9 to represent values 0 to 9 and "A"-"F" (or alternatively "a"-"f") to represent values 10 to 15. Hexadecimal numbers are frequently used by software engineers and system designers because they offer a human-friendly representation of binary-coded data. For example, an 8-bit byte might have values ranging from 00000000 to 11111111 in binary form, which can be succinctly represented as 00 to FF in hexadecimal. Each hexadecimal digit represents four bits (binary digits), often known as a nibble (or nybble).
