Find the length of the missing side.

By focusing on x- axis we can get value of f(3).

In mathematics, a function is represented as a rule that produces a distinct result for each input x. In mathematics, a function is indicated by a mapping or transformation. Typically, these functions are identified by letters like f, g, and h. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The set of values that could be a function's outputs is known as the co-domain.

Given:

We have a function f(x).

Now, we have to find the value of f(3) from the graph

So, If we had the graph of f(x) and wanted to find f(3), we would look for the location on the graph where x = 3, then determine its y-value.

The response to f(3) is that y-value.

The number of mosquitoes on the colony after 4 days is 2800.

The number of days that there are 70,000 mosquitoes will be 114 dad.

The population of a colony of mosquitoes obeys the law of uninhibited growth and there are 1000 mosquitoes initially and there are 1600 after 1 day. The common difference will be:

= 1600 - 1000

= 600

The formula for the arithmetic sequence will be:

= a + (n - 1)d

a = 1000

d = 600

n = 4

The colony after 4 days will be:

= a + (n - 1)d

= 1000 + (4 - 1)600

= 1000 + 1800

= 2800

The number of days that there are 70,000 mosquitoes will be:

a + (n - 1)d = 70000

1000 + 600(n - 1) = 70000

1000 + 600n - 600 = 70000

Collect like terms

600n = 70000 - 1000 + 600

600n = 68400

n = 68400/600

n = 114 days

The circumference of a circle whose area is 9π cm² in terms of pi is 6π centimeters.

A circle is simply a closed 2-dimensional curved shape with no corners or edges.

The area of a circle is expressed mathematically as;

A = πr²

The circumference of a circle is expressed mathematically as;

C = 2πr

Given that the area of the circle is 9πcm², we determine the radius of the circle.

A = πr²

9πcm² = π × r²

r² = 9πcm² / π

r² = 9cm²

r = √9cm²

r = 3cm

Now, we determine the circumference of the circle.

C = 2πr

C = 2 × π × 3cm

C = 6cm × π

C = 6π cm

Therefore, the circumference of the circle is 6π centimeters.

The z-scores for a 67-inch- man and a 62-inch woman are -0.9667 and -0.5526, respectively.

The z-score is a numerical measurement used in statistics to determine the sample data value's relationship to the mean of a group of values, measured in terms of standard deviation from the mean. It is measured as the difference of the sample data value and the sample mean over the standard deviation, such that

z-score = (x – μ) / σ

where x = sample data value

μ = mean

σ = standard deviation

For a 67-inch- man, use the formula to solve for the z-score.

x = 67

μ = 69.9

σ = 3.0

z-score = (x – μ) / σ

z-score = (67 - 69.9) / 3.0

z-score = -0.9667

Do the same for a 62-inch- man, use the formula to solve for the z-score.

x = 62

μ = 64.1

σ = 3.8

z-score = (x – μ) / σ

z-score = (62 - 64.1) / 3.8

z-score = -0.5526

Step-by-step explanation: y = 8x - 15, the 8x represents the slope of this equation

QR = 31 - 18

QR = 13

Answer:

y = -x + 6

Step-by-step explanation:

Slope-intercept is the y = mx + b form, in which m is the slope, and b is the y-intercept.

From the graph provided, we can see that the line intercepts the y axis when the y-coordinate is 6, so we can use 6 as "b" in the equation.y₂

The slope can be found by picking two points on the graph, calling the first point (x₁, y₁) and the second point (x₂, y₂), and applying the formula slope = (y₂ - y₁) ÷ (x₂ - x₁).

Now, we pick two points - I'm choosing (1, 5) and (2, 4) - and apply the formula.

(4 - 5)  ÷ (2 - 1) = -1/1 = -1

Therefore, we know our slope is -1

Putting this all together, we get y = -1x + 6, which we can simplify to y = -x + 6 (since -1 * x is the same as -x)

The graph of h against m is plotted in form of a curve.

Given:

A tree branch is observed to bend as the fruit growing on it increases in size.

The height h in metres of the branch end above the ground is closely approximated by the function [tex]h=2-0.2*1.60^{0.2m}[/tex] where m is the estimated mass, in kilograms, of fruit on the branch.

We have to sketch the graph of h against m.​

The x-axis represents the mass in kg while the y-axis represents the height of the branch above the ground in metres.

Hence a curved graph is obtained by plotting the function.

Answer:

r = 3t/t-1

Step-by-step explanation:

t = r/r-3

1. times both sides by r-3

t(r-3) = r

= tr - 3t = r

2. add 3t to both sides

tr = 3t + r

3. minus r

tr - r = 3t

4. factorise out r

r(t-1)=3t

5. divide by t-1

r = 3t/t-1

Using a system of equations, it is found that the amounts of money that each of Gabriel, Daniel and Edgar have are given as follows:

A system of equations is when multiple variables are related, and equations are built to find the numeric values of each variable, according to the relations built in the context of the problem.

In the context of this problem, the variables are given as follows:

Gabriel has double the amount of Daniel, hence:

x = 2y.

Gabriel has five times the amount of Edgar, hence:

x = 5z.

If Gabriel loans Q14 to Daniel and Q33 to Edgar, they will have the same amount, hence:

x - 47 = y + 14 = z + 33.

Since x = 2y, we can replace into the first two sides of the equality above and solve for y as follows:

2y - 47 = y + 14

y = 61. (Daniel's amount).

The solution for x is given as follows:

x = 2y = 2(161) = 122 (Gabriel's amount).

The solution for z is given as follows:

x - 47 = z + 33

122 - 47 = z + 33

75 = z + 33

z = 75 - 33

z = 42 (Edgar's amount).

The tunnel A will be damaged and truck can pass through tunnel B.

Given that, tunnel A is modeled by x² + y² + 30x + 56 = 0, and tunnel B is modeled by x² – 30x + 16y – 95 = 0.

The general equation of a parabola is: y = a(x-h)² + k or x = a(y-k)² +h, where (h, k) denotes the vertex. The standard equation of a regular parabola is y²= = 4ax.

Part A: x²+y²+30x+56=0

Add 15² on both the sides of a equation

That is, x²+30x+15²+y²=-56+15²

⇒ (x+15)²+y²=169

⇒ (x+15)²+y²=13²

Divide 13² on both the sides of the equation

⇒ (x+15)²/13² + y²/13² =1

Part B:

x²-30x+16y-95=0

Now, x²-30x+16y=95

Add 15² on both the sides of a equation

That is, x²-30x+15²+16y=95+15²

⇒ (x-15)²=320-16y

⇒ (x-15)²=16(20-y)

Part C:

Maximum height:

A: 13 feet

B: 20 feet

Width = 8 feet

A: x+15=8/2=4 y=12.37<13.5

B: x-15=8/2=4 y=19>13.5

Hence, the tunnel A will be damaged and truck can pass through tunnel B.

Answer down below!

Step-by-step explanation:

If we draw this out, we already know that m<7 = 96

Using what we already know, we can figure out the rest

m<6 also equals 96 because m<7 and m<6 are verticle angles

m<3 also equals 96 because m<6 and m<3 are opposite interior angles

m<2 also equals 96 because m<3 and m<2 are verticle angles

Now, to find m<4, simply subtract 96 from 180. That should give you 84

The number of time Easton's song was played during a movie is 4 times.

The first step is to form a system of equations:

40c + 110m = 840 equation 1

c - m = 6

c = 6 + m equation 2

Where:

The system of equations would be solved using the substitution method.
