Which graph represents the linear function below? y-4= (4/3)(x-2)
Answers
Answer:
The graph in the attached figure
Step-by-step explanation:
we have
[tex]y-4=(4/3)(x-2)[/tex]
This is the equation of a line into point slope form
The point is (2.4)
The slope is m=4/3
To plot the line find the intercepts
The y-intercept is the value of y when the value of x is equal to zero
For x=0
y-4=(4/3)(0-2)
y=(-8/3)+4
y=4/3
The x-intercept is the value of x when the value of y is equal to zero
0-4=(4/3)(x-2)
-4=(4/3)x-(8/3)
Multiply by 3 both sides
-12=4x-8
4x=8-12
x=-1
we have the points
(2,4), (0,4/3),(-1,0)
Plot the line
Note With only two points it was necessary to draw the line. The third point was calculated for didactic purposes.

2 squares area is 125 yards and 5 yards. how many yards would it take to fence the two squares in separately
Answers
Answer:
[tex]24\sqrt{5}\ yards[/tex]
Step-by-step explanation:
Let A1 be the area of one square and A2 be the area of second square
So,
A1 = s^2
where s is side of square
[tex]s^2=125\\\sqrt{s^2}=\sqrt{125}\\s=\sqrt{25*5}\\ s= \sqrt{5^2 * 5}\\ s= 5\sqrt{5}[/tex]
So side of one square is [tex]5\sqrt{5}[/tex]
To calculate the length of fence we need to find the perimeter of the square
So,
P1 = 4 * s
[tex]=4*5\sqrt{5} \\=20\sqrt{5}[/tex]
For second square:
[tex]A_2=s^2\\5=s^2\\\sqrt{s^2}=5\\{s}=\sqrt{5}[/tex]
The perimeter will be:
[tex]P_2 = 4*s\\=4 * \sqrt{5} \\=4\sqrt{5}[/tex]
So the total fence will be: P1+P2
[tex]= 20\sqrt{5}+4\sqrt{5} \\= 24\sqrt{5}\ yards[/tex]

Answers
Answer:
The 17th term in arithmetic sequence is 68
Step-by-step explanation:
The general formula of arithmetic sequence is:
aₙ = a₁ + (n – 1)d.
We are given a₆ = 101 and a₉ = 83 and we need to find a₁₇
To find the term a₁₇ we should know a₁ and d. So we would find both
a₆ = a₁ +(6-1)d
101 = a₁ +(5)d
101 = a₁ +5d eq(1)
and
a₉ = a₁ +(9-1)d
83 = a₁ + 8d eq(2)
Subtracting eq(2) from eq(1)
101 = a₁ +5d
83 = a₁ + 8d
- - -
__________
18 = -3d
=> d = 18/-3
=> d = -6
Putting value of d in eq(1)
101 = a₁ + 5d
101 = a₁ + 5(-3)
101 = a₁ -15
=> a₁ = 101+15
=> a₁ = 116
Now finding a₁₇:
aₙ = a₁ + (n – 1)d.
a₁₇ = 116 +(17-1)(-3)
a₁₇ = 116+(16)(-3)
a₁₇ = 116 - 48
a₁₇ = 68
So, the 17th term in arithmetic sequence is 68

A point has coordinates (0, 3). Where is it located in the coordinate plane?
Choose the best answer from the options below:
A x-axis
B y-axis
C quadrant 3
D quadrant 4
Answers
Answer:
A: x-axis
I did a quiz and got it wrong when I choose B: y-axis.
Final answer:
The point with coordinates (0, 3) is on the y-axis, above the origin by 3 units. Therefore, the correct answer is B, the y-axis.
Explanation:
A point with the coordinates (0, 3) is located where the x-coordinate is 0 and the y-coordinate is 3. In the context of a two-dimensional Cartesian coordinate system, this means the point does not move left or right from the origin on the horizontal axis, but it moves up by 3 units on the vertical axis.
Therefore, the correct answer to the question is B, the point is located on the y-axis. It is neither on the x-axis nor in any of the four quadrants since its x-coordinate is zero. Hence, it lies directly above the origin on the y-axis.

For the leather wallets, they need four yards of leather and three yards of canvas. Their production unit has purchased 44 yards of leather and 40 yards of canvas. Let x be the number of leather wallets and y be the number of canvas wallets. If the profit on a canvas wallet is $25 and the profit on a leather wallet is $40, write a function for the total profit for both wallets.
Answers
To find the total profit for both wallets sold by Efficient Homemakers Ltd., use the equation P = 40x + 25y, where x is the number of leather wallets and y is the number of canvas wallets sold.
Explanation:The question involves writing a function for the total profit from selling canvas wallets and leather wallets made by Efficient Homemakers Ltd.
To calculate the total profit, we denote x as the number of leather wallets and y as the number of canvas wallets.
The company makes a profit of $40 for each leather wallet, and $25 for each canvas wallet.
Thus, the total profit P can be represented by the equation:
P = 40x + 25y
This equation represents the total profit as a function of the number of leather wallets (x) and the number of canvas wallets (y) sold.

Option 2 is correct. The approximate weight of the trunk of an American white oak tree with a circumference of 4.5 meters and a height of 8 meters is calculated by finding the volume of the trunk and multiplying it by the tree's density, resulting in approximately 9,694 kilograms.
To calculate the approximate weight of the trunk of an American white oak tree, we first need to estimate its volume and then multiply it by the tree's density. Since the tree trunk is cylindrical, we can use the formula for the volume of a cylinder, [tex]V = \(pi \times r^2 \times h\)[/tex], where r is the radius of the base and h is the height of the cylinder. The circumference is given by C = 2 times pi times r, so we can solve for r by rearranging the formula: [tex]\(r = \frac{C}{2 \times \\pi}\)[/tex]. With a circumference of 4.5 meters, the radius is [tex]\(r = \frac{4.5 \text{m}}{2 \times \pi}\approx 0.716m\)[/tex]. Plugging the radius and the height (8 m) into the volume formula gives V approx pi times (0.716m)^2 times 8 m approx 13.07 m^3.
Knowing the volume, we can find the mass of the trunk by multiplying the tree's volume by its density. The density of American white oak is given as 752 kilograms per cubic meter. The mass (m) is then [tex]m = V \times \ext{density} = 13.07 m^3 \times 752 \frac{kg}{m^3} \approx 9,832.64 kg.[/tex] Rounding off gives us approximately 9,694 kilograms, which is option 2 and is the closest answer provided in the question.

To perform F(g(x)), substitute g(x) into F(x) by squaring g(x) and subtracting 4. The domain of F(g(x)) is all real numbers.
Explanation:The question asks us to perform the composition of two functions - f(x) and g(x). Composition is denoted by (f ∘ g)(x) and involves substituting the output of the inner function (g(x)) into the input of the outer function (f(x)). In this case, we have f(g(x)), which means we need to substitute g(x) into f(x).
First, substitute g(x) into f(x) to get f(g(x)):
f(g(x)) = (g(x))^2 - 4 = (x+2)^2 -4 = x^2 + 4x + 4 - 4 = x^2 + 4x.

Substituting the given points (x1, y1) = (5, 4) and (x2, y2) = (-2, 1), we get:
Distance = √[(-2 - 5)² + (1 - 4)²] = √[( -7)² + (-3)²] = √[49 + 9] = √58 ≈ 7.62.
Therefore, the distance of the line segment joining the two points (5, 4) and (-2, 1) is approximately 7.62 units.

The sum of two numbers is 28. The first number, x, is three
times the second number, y.
Answers
Answer:
x=21
y= 7
Step-by-step explanation:
x+y = 28
x = 3y
Substitute the second equation into the first
3y+y = 28
4y = 28
Divide by 4
4y/4 = 28/4
y = 7
Now we need to find x
x = 3*y
x = 3*7
x = 21

so namely how many times does 1¼ go into 15⅓?
let's firstly convert the mixed fractions to improper fractions and then divide.
[tex]\bf \stackrel{mixed}{1\frac{1}{4}}\implies \cfrac{1\cdot 4+1}{4}\implies \stackrel{improper}{\cfrac{5}{4}}~\hfill \stackrel{mixed}{15\frac{1}{3}}\implies \cfrac{15\cdot 3+1}{3}\implies \stackrel{improper}{\cfrac{46}{3}} \\\\[-0.35em] ~\dotfill\\\\ \cfrac{46}{3}\div\cfrac{5}{4}\implies \cfrac{46}{3}\cdot \cfrac{4}{5}\implies \cfrac{184}{15}\implies 12\frac{4}{15}[/tex]
Solve for x
(x + 10)(x + 10) = 0
Answers
[tex](x + 10)(x + 10) = 0\\x+10=0\\x=-10[/tex]
ANSWER
[tex]x = - 10[/tex]
EXPLANATION
We have the quadratic equation
[tex](x + 10)(x + 10) = 0[/tex]
This quadratic equation is in the factored form.
According to the zero product principle either the first factor is zero or the second is zero.
We apply the zero product principle to obtain:
[tex](x + 10) = 0 \: \: or \: \: (x + 10) = 0[/tex]
This is a repeated factor therefore,
[tex]x = - 10[/tex]
is the repeated root.
