Answer: X = 5.0

Step-by-step explanation:

- since these are right triangles you can use trigonometry to solve this pretty easily

- for this situation, you only have to use sine/sin

sine/sin is [tex]opposite/hypotenuse[/tex]

__________________________________________________________

- to start you just need to identify which side is which:

the side that is labeled 10 is the hypotenusein this case, the shared side is the opposite since you're using sin

- so, for this problem the equation is: [tex]10xSin(45) = 7.071067812[/tex]

__________________________________________________________

- so 7.071067812 is the hypotenuse of the smaller triangle so you just do the same thing again

- start with identifying which side is which:

as said, the side that is shared and 7.071067812 is the hypotenusethe side labeled x is the opposite

- so for this part, the equation is: [tex]7.071067812xSin(45) = 5.0[/tex]

- so X = 5.0

What is the equation of the line that passes through the point (-5,4)(−5,4) and has a slope of 3/5?

Answers

Answer: y = 3/5x + 7

Explanation:

What we know:

The final equation will be in the form y=mx+bThe slope (m) is 3/5The slope must go through the point (-5,4)

How to solve:

By substituting the point the slope passes through into slope-intercept form, we can calculate the y-intercept (b.) From here, we can use our slope and y-intercept values to set up the final equation.

Process:

Finding the y-intercept

Set up equation                                                         y = mx + b

Substitute                                                                   4 = 3/5(-5) + b

Simplify                                                                       4 = -3 + b

Simplify                                                                     +3    +3

Solve                                                                           7 = b

Creating final equation

Set up equation                                                         y = mx + b

Substitute                                                                   y = (3/5)x + 7

Step-by-step explanation:

Solve for x in both equations

Divide both sides by 2:

x<3

3x+2>-4

Subtract 2 from both sides:

3x>-6

Divide both sides by 3:

x>-2

There is this trick you can use when x is on the left side of the equation to find out which way to shade in you graph. Keep in mind this is only for the left side, it will not work if your variable is on the right.

When the symbol is facing left < then shade left, imagine it is pointing which way to shade. x<3 is represented by the 3 picture on the left. When the symbol is facing right > then shade right, again it is pointing which way to shade. x>-2 is represented by the 3 picture on the right.

The circles are not filled in because the symbol is < and > rather than [tex]\leq and \geq[/tex]. When it is greater than or equal to or less than and equal to (represented by the line under the symbol), then the circle is shaded in.

The line which has a gradient of 6 is A. line A

To answer the question, we need to know what the gradient of a line is.

What is the gradient of a line?

The gradient of a line is its slope. It is given by m = Δy/Δx where

Δy = change in y and Δx = change in x.

How to find the line that has the gradient 6?

Now, to find the line that has the gradient of 6, we see that the gradient

m ∝ Δy and m ∝ 1/Δx.

So, for a high value of gradient, we need

a large change in y and a small change in x.

Also, since 6 is positive, the gradient for the line will be positive.

The only line that meets these criteria is line A.

The value of GX is 13 and m ∠ABX is 22°

How to determine the angles

With the information, we have

EX = 4z + 1  and XF = 2z + 7

It is important to note that  EX = XF = GX are congruent, that is, they are equal

Equate EX = XF to determine z

4z + 1 = 2z + 7

Collect like terms

2z = 6

z = 3

We know that  EX = XF = GX and x = 3, substitute into the value of any one

EX = 4(3) + 1

EX = 13

EX = GX

GX = 13

To determine m ∠ABX, we divide m ∠ABC by 2

2. Subtract that amount from one

      [tex]1-0.9=0.1[/tex]

3. multiply the result by 40

    [tex](40)(0.1)=4[/tex]

Hope this helps

Step-by-step explanation:

a probability is always desired cases / total cases.

from the table and given information we know :

there are 40 blue counters.

0.25 = 40/x

x being the total number of counters in the box.

x = 40 / 0.25 = 160

the sum of all probabilities must be 1 (the always true probability), as there are only counters in the box, and one of the 4 colors is always the result.

so,

1 = 0.25 + 0.35 + 0.3 + red-probability

1 = 0.9 + red-probability

red-probability = 1 - 0.9 = 0.1

0.1 = red counters / 160

red counters = 0.1 × 160 = 16

there are 16 red counters in the box.

A certain tranquilizer decays exponentially in the bloodstream and has a ​half-life of 47 hours. How long with it take for the drug to decay to 82​% of the original​ dose?
This is a​ two-step problem.

Answers

The drug will decay to 82% of the initial dosage after 7.18 hours.

Finding the Decay constant(λ):

λ = 0.693 / (half-life)

we are given that the half-life is 47 hours

λ = 0.693 / (47)

λ = 0.01925 /hour

Time is taken for 82% decay:

How do find the decay?

Since decay is first-order, we will use the formula:

[tex]t = \frac{2.303}{0.0192} log\frac{100}{82}[/tex]

Final amount = 100*82/100 = 82 mg

Replacing the values in the equation:

t = 2.303/ 0.0192 x 0.06

t = 7.18 hours

Therefore, the drug will decay to 82% of the initial dosage after 7.18 hours.

A tub contains red, yellow and blue counters. There is ten more yellow than red counters, and the ratio of red to blue counters is 3:4.If there are 20 blue counters, what is the probability of picking a yellow counter?

Answers

Answer:

5/12

Step-by-step explanation:

A ratio of 3:4 means that red counters make up 3/7 of the sum of red and blue counters and blue counters make up 4/7 of the total sum of red and blue counters.

If there is 20 blue counters, then 20 is 4/7 of the sum of the total red and blue counters.

So we need to solve for the total sum.

[tex] \frac{4}{7} x = 20[/tex]

[tex]4x = 140[/tex]

[tex]x = 35[/tex]

So the total amount of red and blue counters are 35,

So this means the amount of red counters is 15.

The amount of yellow counters is 25.

So the total number of counters are 60.

So P(Yellow counters)= 25/60= 5/12

Answers

Last option. The sequence that can be used to to get the figure A'B'C'D' is Reflection about the y-axis followed by a translation to the right by 1 unit.

How to get the reflection of the image

We have an opposite orientation in this question. This based on the fact that (ABCD)' is counterclockwise. While its reflection ABCD is clockwise.

The reflection has to go over a vertical line given that (CD)' and CD are at the bottom. Hence this reflection has to go over  a vertical line.

How do I find the formula for the nth term in a sequence? Like for example the sequence:4,9,14,19 what is the next term?

Answers

Answer:

Step-by-step explanation:

Arithmetic sequence:

   a = first term = 4

   d = common difference =  second term - first term

       = 9 - 4

   d  = 5

[tex]\sf t_n =a +(n -1)*d[/tex]

   = 4 + (n - 1) *5

   = 4 + 5n - 5

    = 5n -1

Check; n= 1 ,  first term = 5*1 - 1 = 5 - 1 = 4

           n = 2,  second term = 5*2 - 1 = 10 -1 = 9

           n = 3, third term = 5*3 - 1 = 15 - 1 = 1

The next term, fifth term  = 5*5 - 1

                                          = 25 - 1

                                          = 24


[tex] {3}^{2x - 2} - 28( {3}^{x - 2} ) + 3 = 0[/tex]
solve for x..... ​

Answers

Answer:

x = 3, x = 0

Given expression:

[tex]3^{2x-2}-28\left(3^{x-2}\right)+3=0[/tex]

rewrite expression

[tex]3^{2x} \times 3^{-2}-28\left(3^{x} \times 3^{-2}\right)+3=0[/tex]

treat [tex]\sf \s3^{x}\:as\:u[/tex], then expression

[tex]u^2 \times 3^{-2}-28\left(u \times 3^{-2}\right)+3=0[/tex]

multiply both sides by [tex]\sf 3^{2}[/tex]

[tex]u^2-28\left u+27=0[/tex]

factor expression

[tex]u^2-27\left u - u + 27=0[/tex]

factor out common terms

[tex]u(u-27) -1( u - 27)=0[/tex]

collect into groups

[tex](u-1)( u - 27)=0[/tex]

set to zero

[tex]u =1, \ u=27[/tex]

Substitute [tex]\sf 3^x = u[/tex], to find x

[tex]3^x = 1, \ 3^x = 27[/tex]

[tex]3^x = 3^0, \ 3^x =3^3[/tex]

[tex]x= 0, \ x = 3[/tex]

A body and tackle with a velocity ratio of 5 is used to raise a mass of 50kg through a vertical distance of 20n at a steady rate if the effort is equal to 80n. Determine (a) distance moved by effort (b)the workdone by the effort in lifting the load (c)the losses in energy involve the operating in machine

Answers

a. Distance moved by effort = 1 meter

b. Work done by effort = 80 Joules

c. Losses in energy = 18 Joules

How to determine the parameters

a. Note that velocity ratio is defined as the ratio of a distance through which any part of a machine moves to the distance moved by its parts

Velocity ratio = distance moved by the effort/distance moved by the body

Where velocity ratio = 5

vertical distance = 20cm

Distance moved by effort = 5 × 0. 20 = 1 meter

b. Formula for work done is given as ;

Work done = Effort × distance moved by effort

Work done = 80 × 1

Work done = 80 Newtons

c. First, let's find the work output

Work output = m g h

Work output = 50 × 9.8 × 0. 20

Work output = 98 Joules

Losses in energy = Work output - work done

Losses in energy = 98 - 80

Losses in energy = 18 Joules
