Answer:

∠JXM and ∠NXP are complementary

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

[tex]m\angle JXM+m\angle MXN+m\angle NXP=180^o[/tex] ----> form a straight line

we have

[tex]m\angle MXN=90^o[/tex]

substitute

[tex]m\angle JXM+90^o+m\angle NXP=180^o[/tex]

[tex]m\angle JXM+m\angle NXP=180^o-90^o[/tex]

[tex]m\angle JXM+m\angle NXP=90^o[/tex]

Remember that

Two angles are complementary, if their sum is equal to 90 degrees

therefore

∠JXM and ∠NXP are complementary

Answer:

a and c

Step-by-step explanation:

The first one is 3/6 = 50%

The second one is 3/8 = 37.5%

The third one is 2/4 = 50%

The fourth one is 5/8 = 62.5%

The ones with the same percent shaded are the first and third

Answer:

a and c

Step-by-step explanation:

A has 3 out of a total of 6 shaded, and that would be 3/6. 3/6 simplifies into 1/2 which is also 50%. Same with c. 2 out of four pieces are shaded, 2/4. 2/4 becomes 1/2 which is also 50%.

Answer:

(x + 3)(3x - 10)

Step-by-step explanation:

[tex]3 {x}^{2} - x - 30 \\ = 3 {x}^{2} + 9x - 10x - 30 \\ = 3x(x + 3) - 10(x + 3) \\ = (x + 3)(3x - 10) \: are \: the \: required \: factors.[/tex]

To factor the expression [tex]3x^2-x-30[/tex], use factoring by grouping. The factored form is (3x + 3)(x - 10).

To factor the expression [tex]3x^2-x-30[/tex], we can use factoring by grouping or the quadratic formula. Let's use factoring by grouping:

Step 1: Multiply the leading coefficient (3) by the constant term (-30) to get -90.

Step 2: Find two numbers whose product is -90 and whose sum is the coefficient of the linear term (-1). In this case, the numbers are -10 and 9.

Step 3: Rewrite the middle term (-x) as the sum of the numbers found in step 2 (-10x + 9x).

Step 4: Group the terms and factor out the greatest common factor from each group (3x(x - 10) + 3(x - 10)).

Step 5: Factor out the common binomial (x - 10) from each group to get the final factored form: (3x + 3)(x - 10).

Answer:

a. [tex]18x^3 -60x^2 + 33x - 45[/tex]

b. No

Step-by-step explanation:

Given:

(3x-9) and [tex]6x^2-2x+5[/tex]

=> the production of them is:

[tex](3x-9)(6x^2-2x+5)[/tex] , we will use distributive law to solve this To do that. we first multiply  [tex]6x^2-2x+5[/tex] by 3x then by -9. This is done as follows

= [tex]3x (6x^2-2x+5) - 9(6x^2-2x+5)[/tex]  [tex]= (3x * 6x^2-3x * 2x+3x *5) - (9* 6x^2-9* 2x+9* 5)\\\\= (18x^3 -6x^2+ 15x) - (54x^2 - 18x +45)[/tex]

Then Open both brackets

= [tex]18x^3 -6x^2+ 15x -54x^2 + 18x -45[/tex]

After that, we group the same terms

= [tex]18x^3 -(6x^2 +54x^2)+ (15x + 18x) -45[/tex]

= [tex]18x^3 -60x^2 + 33x - 45[/tex]

(b) Is the product of (3x-9) and  [tex]6x^2-2x+5[/tex]  equal to the product of (9x-3) and [tex]6x^2-2x+5[/tex]

No, let find the product of (9x-3) and [tex]6x^2-2x+5[/tex] , we will use distributive law to solve this as the above example.

= (9x-3)[tex](6x^2-2x+5)[/tex]

= [tex]9x (6x^2-2x+5) - 3(6x^2-2x+5)[/tex]

=[tex](9x * 6x^2 - 9x * 2x + 9x *5) - (3* 6x^2 - 3 * 2x + 3* 5)[/tex]

= [tex](54x^3 - 18x^2+ 45x) - (18x^2 - 6x +15)[/tex]

After that, we open the bracket to find the same terms

= [tex]54x^3 - 18x^2+ 45x -18x^2 + 6x -15[/tex]

= [tex]54x^3 - 18x^2 -18x^2 + 45x + 6x -15[/tex]

= [tex]54x^3 - 36x^2 + 51x -15[/tex]  

As you can see [tex]54x^3 - 36x^2 + 51x -15[/tex]   ≠[tex]18x^3 -60x^2 + 33x - 45[/tex]

Hope it will find you well.

Answer:

B. -1

Step-by-step explanation:

If we have a parabola whose equation is:

[tex]y=ax^{2} +bx+c[/tex]

The line of symmetry is calculated as:

[tex]x=\frac{-b}{2a}[/tex]

Now, we have the equation [tex]y=ax^{2}-4x+3[/tex] and the line of symmetry is [tex]x=-2[/tex]

Where:

[tex]b=-4\\c=3[/tex]

So, we can replace [tex]b[/tex] by -4 and [tex]x[/tex] by -2 and solve for [tex]a[/tex] using the following equation as:

[tex]x=\frac{-b}{2a}\\-2=\frac{-(-4)}{2a}\\-2(2)a=4\\-4a=4\\a=-1[/tex]

It means that the equation of the parabola is equal to:

[tex]y=-1x^{2}-4x+3[/tex]

Answer:

b=35

Step-by-step explanation:

Let's start by interpreting the question first

b/7 +1=6

Lcm is 7

b+7/7=6

Cross multiply

b+7=7×6

b+7=42

Substrate 7 from both sides

b=42-7

b=35

Therefore the final answer is 35

Answer:

x+20 = 24

Subtract 20 from each side

x+20-20 =24-20

x =4

Answer:

336 plants

Step-by-step explanation:

To find the number of tickseed plants that Michael needs to plant in his garden, we have to find the area of the garden first.

We notice that the garden has the shape of a right triangle: so, we have to find the area of the right triangle.

The area of a triangle is given by the formula

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

where

A is the area

b is the length of the base

h is the height of the triangle

From the figure, we see that:

b = 7 m is the length of the base

h = 24 m is the height of the triangle

Therefore, applying the formula, we find the area of the garden:

[tex]A=\frac{1}{2}7\cdot 24 =84 m^2[/tex]

We also know that Michael wants to plant 4 tickseed plants for each square meter of area; therefore, the total number of plants that Michael will plant is 4 times the area of the garden, so:

[tex]N=4A=4\cdot 84=336[/tex]

Answer:

336 tickseed plants

Step-by-step explanation:

4. Graph

See the graph attached.

Here is how you draw it.

5. Test the profit function for each vertex

The profit function is P(x,y) = 25x + 90y

The vertices shown in the graph are:

The profits with the vertices are:

Thus, the solution that optimizes the profit is producing 0 smaller lifts and 90 larger lifts.

Final answer:

To maximize profits from manufacturing boat lifts, define variables as x for small lifts and y for large lifts, and list the constraints from the welding and packaging departments' available hours alongside non-negative production quantities.

Explanation:

To find how many of each type of boat lifts should be produced to maximize profits, first, we need to define our variables and list our constraints.

List your variables

List your constraints

These constraints represent the limits on production based on the available hours in each department, whilst also considering that the production of both types of lifts must be a non-negative quantity.

Answer:

Explanation:

1. Find the vertical and horizontal components of the initial velocity

a) Horizontal component:

      [tex]v_{0,x}=v_0\times cos(20\º)=135ft/s\times cos(20\º)=126.86ft/s[/tex]

b) Vertical component:

      [tex]v_{0,y}=v_0\times sin(20\º)=135ft/s\times sin(20\º)=46.17ft/s[/tex]

2. Find the time when the ball runs 380 feet horizontally:

          [tex]x=v_{0,x}\times t\\\\380ft=126.86ft/s\times t[/tex]

          [tex]t= (380ft)/(126.86ft/s)=2.995s\approx 3.0s[/tex]

3. Find the height of the ball when the time is 3.0s

       [tex]y=y_0+v_{0,y}\times t-gt^2/2[/tex]

     [tex]y=3ft+46.17ft/s\times 3.0s-32.174ft/s^2\times (3.0s)^2/2[/tex]

     [tex]y=-3.3ft[/tex]

This result means that the ball does not reach the wall because it has fallen to the ground (when y = 0) before 3.0s.

Look at all the steps above. They lead to a double solution. The symbol

[tex]x=\pm 5[/tex]

means that [tex]x[/tex] can be either positive or negative 5. You can't accept negative values for lengths, so you're left with one option only.

Answer:

Fraction=3/10

Decimal=0.3

Percent=30%

Step-by-step explanation:

First we have to add 12+16 so we can find how many marbles are left

12+16=38

Then, we subtract it from the total number of marbles.the outcome of this operation would be equivalent to the number of blue marbles

40-38=12

There are 12 blue marbles.

Now, the we have to use experimental probability if you are familiar with the term is that the number of outcomes(the blue marbles) must be over the total sample space(total marbles) in a fraction.

Probability=

Answer:

90t-21t=69t

Step-by-step explanation:

4:00pm to 6:00 am is 14 hours. 14 x 1.5 is in fact 21 which means the temperature dropped 21 degrees in those 14 hours.

The equation to represent the temperature after a certain number of hours is t = 90 - 1.5h.

The equation to represent the temperature, t, after h hours can be written as: t = 90 - 1.5h.

Step-by-step explanation:

Answer:

The point (56, 1.75) is on the line.

Step-by-step explanation:

Given two points, we can get the slope (m) as follows:

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

where (x1, y1) and (x2, y2) are the points. Replacing with (8, 0.25) and (16, 0.5):

m = (0.5 - 0.25)/(16 - 8) = 0.03125

The point-slope form of a line is:

y - y1 = m(x - x1)

Replacing with data:

y - 0.25 = 0.03125(x - 8)

To know if point (56, 1.75) is on the line, we have to replace x = 56 in the obtained equation and check y-value, as follows:

y - 0.25 = 0.03125(56 - 8)

y - 0.25 = 1.5

y = 1.5 + 0.25 = 1.75

Then, the point is on the line. This means that there are 56 ounces in 1.75 quarts.
