Answer:

All you gotta do is go to "desmos" and type in all of the 4 solutions. A, B, C, and D. and see which answer matches the graph

Step-by-step explanation:

Answer:

Solution: To determine mass of the block we can use second Newton' law \vec F=m\vec a

F

=m

a

. The force and acceleration according the problem is directed along a horizontal surface, and we can omit the vector sign in Newton's law. The force we know F=45NF=45N, thus we should deduce the acceleration. The problem does not specify the initial speed at which time began to count, so for the first time interval, we may write the kinematics equation in the form

(1) S_1=v_1\cdot t_1+a\frac {t_1^2}{2}S

=v

Note that during the first time interval, the speed of the block increased in accordance with the law of equidistant motion and it became the initial speed of the second interval, i.e.

(3) v_2=v_1+a\cdot t_1v

+a⋅t

Substitute (3) to (2) we get

(4) S_2=(v_1+a\cdot t_1)\cdot t_2+ a\frac{t_2^2}{2}=v_1\cdot t_2+a\cdot t_1\cdot t_2+a\frac{t_2^2}{2}S

3850 of those 6 person teams contain at most 3 men.

Step-by-step explanation:

The order in which the people are selected is not important, which means that the combinations formula is used to solve this question.

It drove 30.08 kilometers in an hour.

Combinations formula:

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

0 men:

[tex]C_{8,6} = \frac{8!}{2!6!} = 28[/tex]

1 men:

5 women from a set of 8

1 men from a set of 7. So

[tex]C_{8,5}C_{7,1} = \frac{8!}{3!5!} \times \frac{7!}{1!6!} = 392[/tex]

2 men:

4 women from a set of 8

2 men from a set of 7. So

[tex]C_{8,4}C_{7,2} = \frac{8!}{4!4!} \times \frac{7!}{2!5!} = 1470[/tex]

Answer:

LP = 15

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is

[tex]\frac{LM}{LN}[/tex] = [tex]\frac{LQ}{LP}[/tex] , substitute values

[tex]\frac{4}{10}[/tex] = [tex]\frac{LQ}{LQ+QP}[/tex]

[tex]\frac{2}{5}[/tex] = [tex]\frac{LQ}{LQ+9 }[/tex] ( cross- multiply )

5LQ = 2(LQ + 9) = 2LQ + 18 ( subtract 2LQ from both sides )

3LQ = 18 ( divide both sides by 3 )

LQ = 6

Then

LP = LQ + QP = 6 + 9 = 15

Answer:

  a. the stretch

Step-by-step explanation:

The function 2f(x+1) -4 represents a vertical stretch by a factor of 2, a horizontal translation left 1 unit, and a vertical translation down 4 units.

Either the horizontal translation or the vertical stretch can be done first, because their effects are independent of one another. If the vertical translation is done first, the stretch will double it—which is not what you want.

__

Since the vertical stretch must be done before the vertical translation, it is reasonable to claim the vertical stretch must be done first.

_____

Additional comment

If you claim the horizontal stretch must be done first, that places no restriction on the sequence of vertical transformations. Hence the graph may be incorrect when only that restriction is applied.

Answer:

[tex]\text{(D) }\frac{\sin 110^{\circ}}{x}=\frac{\sin 40^{\circ}}{20}[/tex]

Step-by-step explanation:

We can use the Law of Sines to solve this problem. The Law of Sines works for any triangle and states that the ratio of any angle and its opposite side is maintained throughout all angles of the triangle:

[tex]\frac{\sin A}{a}=\frac{\sin B}{b}=\frac{\sin C}{c}[/tex]

In the figure, the angle marked 110 degrees has an opposite side labelled [tex]x[/tex]. However, the angle opposite to the side marked 20 is still unknown, so let's find it.

The sum of the interior angles of a triangle is always 180 degrees. Therefore, let the third angle be [tex]\theta[/tex]. We have:

[tex]\theta + 110^{\circ}+30^{\circ}=180^{\circ},\\\theta+140^{\circ}=180^{\circ},\\\theta=40^{\circ}[/tex]

Now we have the relevant angle and we can set up the proportion:

[tex]\boxed{\frac{\sin 110^{\circ}}{x}=\frac{\sin 40^{\circ}}{20}}[/tex]

The percentage of failed students is 12%

We have,

Total number of students = 175

Number of students passed = 154

We need to calculate the percentage of the number of failed students.

The formula used to calculate the percentage is:

     [tex]\frac{ required~value}{total~value} \times 100[/tex]

Here,

Total value:

= Total number of students

= 175

Required value:

= Number of students failed

= Total number of students - Number of students passed

= 175 - 154

= 21

Percentage of failed students:

=  [tex]\frac{21}{175} \times 100\\[/tex]

= ( 21 x 100 ) / 175

= 2100 / 175

= 12 %

The percentage of failed students is 12%.

Answer:

I think 5q+3(8-q) =36 is the answer for this question

Based on the amount the restaurant manager spends on the juice mixture, the amount of cherry juice can be found as 5q + 3(8 – q) = 8.

Assuming the cherry juice is q and the lime juice is r, the following formulas would be true:

q + r = 8

5q + 3r = 36

The first equation can be rewritten as:

q + r = 8

r = 8 - q

Using substitution into the second formula we get:

5q + 3r = 36

5q + 3(8 - q) = 36

This is it

I'm just going to start writing the email XD (btw, bold = non-email parts/me talking)

Hey (Friend name),

You kinda missed math the other day, and being the nice friend I am, I decided to catch you up on what we learned.

We learned how to solve a system of equations using the substitution method.

A system of equations is a set of two or more equations with common variables. We use those two equations to solve for the variables.

One example might be:

3x+y=3

4x+3y=10

Solving each of these two equations by themselves would be impossible, so this is where the substitution method comes in.

Solving by substitution means that you first solve one equation for a variable, and then you substitute the value of that variable into the other equation. You might understand better if you see how I use this method to solve the previous system.

Step 1: Solve for y.

 3x+y=3

 Subtract 3x from each side.

 y=3-3x

Step 2: Use the substitution method (plug in the y value).

 4x+3y=10

 4x+3(3-3x)=10

 See how we plugged in the right side of the equation that is equal to y? Now       only the x variable is left and we can easily solve it!

Step 3: Simplify to get x.

 4x+9-9x=10

 -5x=1

 x=-1/5

Step 4: Use the substitution method AGAIN (for the y).

 Now we plug in the x value into the equation for y.

 y=3-3x

 y=3-3(-1/5)

 y=3-(-3/5)

 y=18/5

The final answer is x=-1/5, y=18/5.

As you can see, using the substitution method to solve two impossible equations is how we can get the values of the variables they share! It's simple, quick, and easy!

Sincerely,

Given:

The given equation is:

[tex]16-3p=\dfrac{2}{3}p+5[/tex]

To find:

The value of p.

Solution:

We have,

[tex]16-3p=\dfrac{2}{3}p+5[/tex]

Multiply both sides by 3.

[tex]3(16-3p)=3\left(\dfrac{2}{3}p+5\right)[/tex]

[tex]48-9p=2p+15[/tex]

Isolating the variable terms, we get

[tex]48-15=2p+9p[/tex]

[tex]33=11p[/tex]

Divide both sides by 11, we get

[tex]\dfrac{33}{11}=p[/tex]

[tex]3=p[/tex]

Therefore, the required solution is [tex]p=3[/tex].
