What is the equation of a line, in general form, with a slope of -2 and a yintercept of 8?
x+2y-8=0
2x+y-8 = 0
2x-y+ 8 = 0​

Answer:

A. [tex]h=\dfrac{2A}{b}[/tex]

Step-by-step explanation:

You are given formula

[tex]A=\dfrac{1}{2}bh[/tex]

Multiply this equation by 2 to get rid of fraction:

[tex]2A=bh[/tex]

Divide this equation by b to find h in terms of A and b:

[tex]h=\dfrac{2A}{b}[/tex]

Answer:

D

Step-by-step explanation:

Using the midpoint formula

midpoint of 2 points (x₁, y₁ ) and (x₂, y₂ ) is

[ [tex]\frac{1}{2}[/tex](x₁ + x₂), [tex]\frac{1}{2}[/tex](y₁ + y₂ ) ]

let (x₁, y₁ ) = (- 1, 5) and (x₂, y₂ ) = (5, 5), then midpoint is

[ [tex]\frac{1}{2}[/tex](- 1 + 5), [tex]\frac{1}{2}[/tex](5 + 5) ]

= (2, 5) → D

The midpoint of the segment is (2,5).

To find the midpoint of a line segment with endpoints [tex]\((-1, 5)\) and \((5, 5)\)[/tex], we can use the midpoint formula:

[tex]\[ \text{Midpoint} = \left( \frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2} \right) \][/tex]

Given the endpoints:

[tex]\( x_1 = -1 \), \( y_1 = 5 \)[/tex] (coordinates of the first point)

[tex]\( x_2 = 5 \), \( y_2 = 5 \)[/tex] (coordinates of the second point)

Now, let's plug these values into the midpoint formula:

[tex]\[ \text{Midpoint} = \left( \frac{-1 + 5}{2}, \frac{5 + 5}{2} \right) \][/tex]

[tex]\[ = \left( \frac{4}{2}, \frac{10}{2} \right) \][/tex]

[tex]\[ = \left( 2, 5 \right) \][/tex]

Therefore, the midpoint of the segment is (2, 5)

Among the given options, the correct one is option D: (2, 5).

9/n  =  10/m

Answer: Hi, in the equation 9*m = 10*n the proportion is 9 to 10, which means that 9 times the number m is equal to 10 times the number n.

So n is proportional to m in the way that n= (9/10)*m

and m is proportional to n in the way that m= (10/9)*n

This means that the proportion can be written as 9 to 10, or 9:10.

I think it is bottom right because it goes through the most points.

The answer is D.

If you multiply them all together the answer (without simplifying), it should equal 210/9, you then simplify the numerator and denominator by 3 and you get 70/3.

Answer:

D

Step-by-step explanation:

Given

[tex]\frac{5}{3}[/tex] × [tex]\frac{2}{3}[/tex] × [tex]\frac{21}{1}[/tex]

Multiply numerators/ denominators

= [tex]\frac{5(2)(21)}{3(3)(1)}[/tex]

= [tex]\frac{210}{9}[/tex]

Cancel the numerator/denominator by dividing both by 3

= [tex]\frac{70}{3}[/tex] → D

Answer:

The height of the tree is [tex]64.94\ ft[/tex]

Step-by-step explanation:

Let

y ----> the height of the tree

we know that

[tex]tan(33\°)=y/100[/tex] ----> the function tangent is equal to divide the opposite side angle of 33 degrees by the adjacent side angle of 33 degrees

Solve for y

[tex]y=(100)tan(33\°)=64.94\ ft[/tex]

The height of the tree can be calculated using the formula 'Height of tree = tan(33 degrees) * distance from the tree'. Substituting the given values, the tree should be approximately 65.45 feet tall.

John can measure the height of the tree using trigonometric principles. In this case, the problem involves a right triangle, where the height of the tree forms one side (opposite to the angle of elevation), the distance John is from the tree forms the base (adjacent to the angle of elevation), and the line of sight to the top of the tree forms the hypotenuse. The tangent of the angle of elevation (33 degrees in this case) is equal to the height of the tree divided by the distance from the tree.

Therefore, to calculate the height of the tree, we need to find the tangent of the given angle and multiply it by the distance from the tree:
Height of tree = tan(33 degrees) * distance from tree

= tan(33) * 100 feet
Approximately, the tree should be around 65.45 feet tall.

Answer:

The value 1.8 represent the club's total number of members today or the present number of members

Step-by-step explanation:

Given an exponential function;

[tex]y=ab^{x}[/tex]

b is the base or the growth factor

a is the initial value, that is the value of y when x = 0

We have been given the exponential function;

[tex]y=1.8(1.02)^{12t}[/tex]

The value 1.8 simply represents the initial value of y. Plug in t = 0 in the equation;

[tex]y=1.8(1.02)^{12(0)}=1.8[/tex]

Therefore, the value 1.8 represent the club's total number of members today or the present number of members.

Answer is C

Step-by-step explanation:

Answer:

a) Domain: -∞ < x < ∞

b) Cost required to manufacture 3500 items is $15,900.

c) Number of items she can manufacture is 5208 if cost is kept at $20,000

Step-by-step explanation:

a) What is the reasonable domain of the function?

The function is C(x) = 7,500 + 2.4x

The domain of the function is the set of values for which the function is defined and valid.

In the given function there is no constraint or undefined points so domain is:

-∞ < x < ∞

b) What is the cost of 3,500 items?

We are given x = 3500 and we need to find the cost.

Putting values in the function given:

C(x) = 7,500 + 2.4x

C(x) = 7,500 + 2.4 (3500)

C(x) = 7500 + 8400

C(x) = 15,900

Cost required to manufacture 3500 items is $15,900.

c) If costs must be kept below $20,000 this month, what is the greatest number of items she can manufacture?

We are given cost, and we need to find x

C(x) = 7,500 + 2.4x

20,000 = 7500 +2.4x

20,000 - 7500 = 2.4x

12500 = 2.4 x

=> x = 12500/2.4

x= 5208.3 ≅ 5208

So, Number of items she can manufacture is 5208 if cost is kept at $20,000

The slope of this line is -1.

The slope formula is useful:

m = (y2 -y1)/(x2 -x1)

where:

m is the slope of the line

y1 and y2 are the y-coordinates of two points on the line

x1 and x2 are the x-coordinates of the two points on the line

 m = (2 -4)/(0 -(-2)) = -2/2 = -1

The slope of this line is -1.

The points on the line drop 1 unit for each 1 unit to the right.

 m = rise/run = -1/1 = -1

Answer: 4

Step-by-step explanation:

The degree is the highest exponent , in which in this problem it is 4. The 3x counts as an exponent of 1 because the variable x is 1, and the 2 counts as an exponent of zero. Which means the degree is 4.

Answer:

y = - 7

Step-by-step explanation:

The y- intercept is the point on the y- axis that the line passes through.

The line passes through the y- axis at (0, - 7), hence

the y- intercept is - 7

Slope-intercept form: y = mx + b   [m is the slope, b is the y-intercept or the y value when x = 0 ---> (0 , y)]

Since you know m = -3, you can plug that into the equation

y = mx + b

y = -3x + b       To find b, plug in the point they gave you into x and y, but since x = 0, your y-intercept is -7

Answer:

Step-by-step explanation:

If she starts out with 73 and drops 5 she is left with 68, an you cannot evenly divide 68 and 13 so you divide it as much as you can evenly which is five containers leaving 3 extra cupcakes.

For this case we have that initially there are 73 cupcakes, if Leda dropped 5 then we are left with:

[tex]73-5 = 68[/tex]

Now, you must equally divide the 68 cupcakes into 13 containers:

putting 5 cupcakes in each of the 13 containers we have;

[tex]13 * 5 = 65[/tex]

[tex]68-65=3[/tex]

So, we have 3 cupcakes left.

[tex]f(-1) = 1[/tex]

Step-by-step explanation:

Given

f(x) = [tex]-x^{3}-x^{2} +1[/tex]

Finding f(-1) means, we have to put -1 in the places of x in the function,

So, putting x=-1 in the function

[tex]f(-1) = (-1)^{3} - (1)^{2} +1[/tex]

As the power 3 is odd, the minus will remain the same, while in the 2nd term minus will be eliminated due to even power. So,

=> [tex]-1-1+1[/tex]

=> 1

Domain = {3,4,9}

Range = {2, 6, 8, 9.5}

Given relation is NOT a function.

Step-by-step explanation:

Given relation is relation is ((9,6), (3,8),(4,9.5), (9,2)}.

Now we need to determine if given relation is a function or not.

We also need to find the domain and range.

((9,6), (3,8),(4,9.5), (9,2)}

​Domain is basically the collection of x-values

So Domain = {3,4,9}

Range is basically the collection of y-values

So Range = {2, 6, 8, 9.5}

Since given relation contains repeated x-value "9".

So the given relation is NOT a function.

- 1/2x > 6

Divide both sides by -1/2:

x < -12   (Note the inequality sign flips when we divide by a negative value).

Answer: {x |x ∈ R, x < -12}

Step-by-step explanation:

Given the following inequality:

[tex]-\frac{1}{2}x>6[/tex]

You can find the solution set by solving for the variable "x".

Then, to solve for the variable "x" you need to multiply both sides of the inequality:

[tex](-\frac{1}{2}x)(2)>(6)(2)[/tex]

[tex]-x>12[/tex]

And finally, you must multiply both sides of the inequality by (-1). Notice that the direction of the symbol of the inequality will change:

[tex](-x)(-1)>(12)(-1)[/tex]

[tex]x<-12[/tex]

Therefore, the solution set is: {x |x ∈ R, x < -12}
