Answer:

yes

Step-by-step explanation:

To determine if the point lies on the line substitute the coordinates into the left side of the equation and if equal to the right side then the point lies on the line

- 3 + (4 × 4) = - 3 + 16 = 13 = right side

Hence (- 3, 4) lies on the line x + 4y = 13

The perimeter of a square is four times the side, since you have to sum all sides, and they're all the same length:

[tex]P=n+n+n+n=4n[/tex]

This is direct variation, because we have

[tex]P=4n \iff \dfrac{P}{n}=4[/tex]

and if the ratio between two variables is constant (in this case, 4), then the two variables are in direct variation.

The perimeter of a square is directly proportional to its side length, therefore it's an example of direct variation.

Yes, the perimeter (P) of a square with side length (n) is an example of direct variation. In this case, P is directly proportional to n. To understand this, think of a square. A square has four equal sides. Thus, its perimeter (P) is n times 4, or P = 4n. If n is increased, the perimeter also increases proportionally, which supports that it's a direct variation relationship. A change in one quantity leads to a proportional change in the other one.

To simplify 2.4 times 10¹³ divided by 8 times 10⁷, subtract exponents to get 2.4 times 10⁶, or adjust the numerator and divide by 8 to find 3 times 10⁵ as the result to perform the calculation mentally.

Explanation:

When dealing with the division of expressions involving powers of ten, using exponent subtraction is often useful to simplify the problem. For the expression 2.4 times 10¹³ divided by 8 times 10⁷, one approach is to directly subtract the lower exponent from the higher one, yielding 2.4 times 10¹³⁻⁷, which simplifies to 2.4 times 10⁶. However, to perform in my head, an alternative way is to adjust the numerator by dividing it by 8, which results in 0.3 times 10¹³. Moving the decimal point in the numerator gives 3 times 10¹², and then dividing by 10⁷ gives a final result of 3 times 10⁵.

The elevator starts at street level (0), goes down to -4 and then rises 9 floors to reach the conference center. The sum of -4 + 9 gives 5 which is the floor number for the conference center.

The elevator starts at street level, which we are defining as floor 0. It then goes down 4 floors, so it's at -4. However, it then travels up to the conference center, moving a total of 9 floors. You need to add these 9 floors to where the elevator currently is. So you'll calculate -4 (the current floor number) + 9 (the number of floors it goes up) which equals 5. Therefore, the conference center is on the 5th floor.

Answer:

Step-by-step explanation:

Part a)

Let the volume of water in glass pitcher be 'V'

Now it is given that 1/8 of water is poured in 2 glasses

Thus the volume of water in each glass is

[tex]V'=\frac{1}{2}\times \frac{V}{8}=\frac{V}{16}[/tex]

Part b)

Now it is given that volume of water in each glass is 3 fluid ounces thus to obtain the original volume we euate the volume obtained in part a with 3. Thus

[tex]\frac{V}{16}=3\\\\\therefore V=3\times 16=48ounces[/tex]

Part c)

After pouring out 1/8 water from the orifinal glass the volume of watre that remains in the pitcher euals

[tex]V_{rem}=V-\frac{V}{8}=\frac{7V}{8}[/tex]

Now since 1/4 of the above volume is poured out which euals

[tex]V_{poured}=\frac{1}{4}\times \frac{7V}{8}=\frac{7V}{32}[/tex]

Thus the volume of water that remains euals

[tex]V'_{rem}=\frac{7V}{8}-\frac{7V}{32}=\frac{21V}{32}[/tex]

Applying the value of V we get

[tex]V'_{rem}=\frac{21\times 48}{32}=31.5[/tex]ounces

first off, those two points above do not give that point-slope form, however, the issue is just what's the standard form.

keeping in mind that standard form for a linear equation means

• all coefficients must be integers, no fractions

• only the constant on the right-hand-side

• all variables on the left-hand-side, sorted

• "x" must not have a negative coefficient

[tex]\bf y+1=\cfrac{2}{3}(x-8)\implies \stackrel{\textit{multiplying both sides by }\stackrel{LCD}{3}}{3(y+1)=3\left( \cfrac{2}{3}(x-8) \right)}\implies 3y+3=2(x-8) \\\\\\ 3y+3=2x-16\implies 3y=2x-19\implies -2x+3y=-19 \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ ~\hfill 2x-3y=19~\hfill[/tex]

The equation of the line that passes through the points (8,1) and (2,-5) in standard form is 2x - 3y = 13.

To find the equation of the line that passes through the given points we need to understand the slope (rise over run) and the y-intercept. The provided equation, y + 1 = 2/3(x - 8), is in point-slope form (which is y - y1 = m(x - x1) where m is the slope and (x1, y1) is a point on the line). To transform to the standard form, we distribute the 2/3 on the right side, subtract 1 from both sides to move y to the left side.

Following these steps, we get: 2x - 3y = 13, as the equation of the line in the standard form.

Step-by-step explanation:

-3.3m = -1.1

Divide both sides by -3.3

m = -1.1

-3.3

The solution to the equation -3.3m = -1.1 is m = 1/3 or approximately 0.33. This was determined by dividing both sides of the equation by -3.3.

The problem -3.3m = -1.1 is a simple one-step equation which can be solved by isolating the variable. Here the variable is m. Dividing both sides of the equation by -3.3, we get m = (-1.1/-3.3). This simplifies to m = 1/3 ≈ 0.33. So, the solution to the equation is m = 0.33.

What we did here is an application of the principle that whatever you do to one side of an equation, you should do to the other side as well. This principle is essential in solving mathematical equations.

Answer:

45 Miles

Step-by-step explanation:

Speed = Distance / Time

Distance = Speed * Time

= 7.5 * 6 = 45 Miles

Final answer:

To find the distance traveled by the bicycle rider, multiply the average speed of 7.5 mph by the time of travel of 6 hours, resulting in a total distance of 45 miles.

Explanation:

Calculating Distance Traveled

To calculate the distance traveled by the bicycle rider, we use the formula that relates average speed, distance traveled, and time of travel:

Average speed = Distance traveled / Time of travel

In this scenario, the bicycle rider's average speed is given as 7.5 mph, and the time of travel is 6 hours. Therefore, the distance traveled can be calculated by multiplying the average speed by the time of travel:

Distance traveled = Average speed × Time of travel

Distance traveled = 7.5 mph × 6 h = 45 miles

Therefore, the bicycle rider traveled a total of 45 miles.

If we rant their axis of symmetry from least to greatest, it would be:

f(x),h(x), g(x)

Step-by-step explanation:

Axis of symmetry is a line that divides an object into two equal halves, thereby creating a mirror like reflection of either side of the object.

We can find axis of symmetry with the help of formula:

x = -b/2a

We know that the quadratic equation is written like:

ax^2+bx+c

where a,b are coefficients: c is constant term and x is variable

Now look at the function f(x)= 3x^2

For this function we have a= 3, b =0 , c=0

Put the values in the above mentioned formula:

x = -b/2a

x = - (0)/2(3)

x = 0/6 = 0

Thus the axis of symmetry for f(x) = 0

Now  g(x) = x2 - 4x + 5

a = 1 , b = -4 , c =5

x = -b/2a

x = -(-4)/2(1)

x = 4/2

x = 2

Axis of symmetry for g(x) = 2

h(x) = -2x2 + 4x + 1

a = -2 , b =4 , c=1

x = -b/2a

x = -(4)/2 (-2)

x = -4 /-4

x = 1

Axis of symmetry for h(x) = 1

So if we rant their axis of symmetry from least to greatest, it would be:

f(x),h(x), g(x)

The correct calculation for the total cost to seed an area of 80 feet by 40 feet is $45.00, substantially less than the incorrect $1067 identified due to proper area conversion and cost calculation.

Explanation:

The question about the cost of seeding an area of 80 feet by 40 feet involves calculations for area conversion, determining the number of seeds needed, and calculating the total cost. The initial step involves calculating the area in square feet (80 x 40 = 3200 sq ft) and then converting this area into square yards by dividing by 9 (since there are 9 sq ft in a sq yd), which equals approximately 355.56 sq yds. The bags of grass seed required is then determined by the coverage rate of 1 bag per 25 square yards, yielding about 14.22 bags. However, since you cannot purchase a fraction of a bag, you would need to buy 15 bags of seeds. At a cost of $3.00 per bag, the total cost is $45.00, contrasting significantly with the incorrect calculation provided in the question.
