What is the logarithmic formula 10000= 625/8*2^t ?

Answer:

Step-by-step explanation:

Answer: y = 50

Step-by-step explanation:

Supplement angles are two angles that sums up to 180°. So we could interfere that (8x - 14)° and (5y + 16)° are supplement angles. But before we move on, we should first solve for x. Opposite angles are equal. So therefore the angle opposite to 8x - 14 is also equal to 8x - 14. Guess what? Corresponding angles are also considered equal. So we could then conclude as following:

5x + 34 = 8x - 14

With the equation above we can now solve for x. We first add 14 on both sides.

5x + 48 = 8x

We then substract 5x on both sides.

48 = 3x

We finally divide 3 on both sides. This gives us the value of x.

x = 16

Now that we know the value of x, we could now solve (8x - 14)°. We first start by substituting in the equation.

8(16) - 14

We then multiply 8 with 16.

128 - 14

We finally substract 14 from 128. This gives now the value of the angle

114°

Now that we know this, we could now solve for y. Like I said earlier, supplement angles add up to 180°. So our equation should go as following:

114 + (5y + 16) = 180

We first add like terms together.

5y + 130 = 180

We then substract 130 on both sides

5y = 50

We finally divide 5 on both sides of the equation.

y = 50

Step-by-step explanation:

given,

30m of material cost = £210

so, cost of 1m material = 210/30 = £7

therefore, cost of 1m material is £7

now,

cost of 18m Material = 18 × 7 = 126

therefore, cost of 18m material is £126.

hope this answer helps you dear!

Answer: 126

Step-by-step explanation:

30 m of material cost 210

1 m of material cost [tex]\frac{210}{30}[/tex] Or 7

18 m of material cost 7 × 18 = 126

Step-by-step explanation:

Given,

ratio of HI, IJ , Jk = 2 : 1 : 2

let their value be

HI = 2x

IJ = x

JK = 2x

HK = 25

according to question,

HI + IJ + JK = Hk

now, after inserting the values we got,

→ 2x + x + 2x = 25

→ 5x = 25

→ x = 25/5 = 5

→ x = 5

therefore value of,

HI = 2x → 2×5 = 10

IJ = x → 5

JK = 2x → 2×5 = 10

Hence, value of JK is 10.

hope this answers helps you dear...take care and may u have a great day ahead!

Because I need points

Step-by-step explanation:

the total length of all lines is 100.

there are 2 times a d line, and 5 times an x line.

well, what we have here is an equation :

2d + 5x = 100

2d = 100 - 5x = 5×(20 - x)

d = 5/2 × (20 - x) = 50 - 5x/2

take whatever form fits best to what your teacher does in class.

This is one pathway to prove the identity.

Part 1

[tex]\frac{\sin(\theta)}{1-\cos(\theta)}-\frac{1}{\tan(\theta)} = \frac{1}{\sin(\theta)}\\\\\frac{\sin(\theta)}{1-\cos(\theta)}-\cot(\theta) = \frac{1}{\sin(\theta)}\\\\\frac{\sin(\theta)}{1-\cos(\theta)}-\frac{\cos(\theta)}{\sin(\theta)} = \frac{1}{\sin(\theta)}\\\\\frac{\sin(\theta)*\sin(\theta)}{\sin(\theta)(1-\cos(\theta))}-\frac{\cos(\theta)(1-\cos(\theta))}{\sin(\theta)(1-\cos(\theta))} = \frac{1}{\sin(\theta)}\\\\[/tex]

Part 2

[tex]\frac{\sin^2(\theta)}{\sin(\theta)(1-\cos(\theta))}-\frac{\cos(\theta)-\cos^2(\theta)}{\sin(\theta)(1-\cos(\theta))} = \frac{1}{\sin(\theta)}\\\\\frac{\sin^2(\theta)-(\cos(\theta)-\cos^2(\theta))}{\sin(\theta)(1-\cos(\theta))} = \frac{1}{\sin(\theta)}\\\\\frac{\sin^2(\theta)-\cos(\theta)+\cos^2(\theta)}{\sin(\theta)(1-\cos(\theta))} = \frac{1}{\sin(\theta)}\\\\[/tex]

Part 3

[tex]\frac{\sin^2(\theta)+\cos^2(\theta)-\cos(\theta)}{\sin(\theta)(1-\cos(\theta))} = \frac{1}{\sin(\theta)}\\\\\frac{1-\cos(\theta)}{\sin(\theta)(1-\cos(\theta))} = \frac{1}{\sin(\theta)}\\\\\frac{1}{\sin(\theta)} = \frac{1}{\sin(\theta)} \ \ {\checkmark}\\\\[/tex]

As the steps above show, the goal is to get both sides be the same identical expression. You should only work with one side to transform it into the other. In this case, the left side transforms while the right side stays fixed the entire time. The general rule is that you should convert the more complicated expression into a simpler form.

We use other previously established or proven trig identities to work through the steps. For example, I used the pythagorean identity [tex]\sin^2(\theta)+\cos^2(\theta) = 1[/tex] in the second to last step. I broke the steps into three parts to hopefully make it more manageable.

Answer:

x = -4

Step-by-step explanation:

Step 1: Apply distributive property.

Step 2: Combine like terms.

Step 3: Subtract 8 from both sides.

Step 4: Divide both sides by 2.

Step 5: Check if solution is correct.

Therefore, x = -4.

Answer:

1) 5.091

2) 54.6731

3) 2.954

4) 0.17278

5) 68.031

Answer:

Please see below.

Step-by-step explanation:

f^-1 (x) essentially means the reverse.

We can substitute y for x in the equation and solve for y:

x = 4y -1

x+1 = 4y

y = (x+1)/4

so that is our answer for the first one:

f^-1(x) = (x+1)/4

We do the same trick for the second question:

x = 2y +1

x-1 = 2y

y = (x-1)/2

so the answer is f^-1(x) = (x+1)/2

The last question is slightly more complex, we can write is as:

x = 2y/(y-1)

x(y-1) = 2y

yx -x = 2y

yx = 2y + x

yx - 2y = x

y(x-2) = x

y = x/(x-2)

so the answer is x/(x-2)

Answer:

Base-3 mi

Height-8 mi

Step-by-step explanation:

The area of a parallelogram is base*height.

Base*height=24

Now we just need to number that multiply to get 24. Those numbers can be 3 and 8 because 3*8=24.

The dimension of the parallelogram are 1 x 24, 2 x 12, 4 x 6, 8 x 3, and 24 x 1.

The opposite sides of the parallelogram are parallel and congruent. Let H be the height and W be the width of the parallelogram.

Then the area of the parallelogram will be

Area of the parallelogram = H × W square units

The area of the parallelogram is 24 square miles.

Then the dimension of the parallelogram is given as,

Area = 24

Area = 2 x 2 x 2 x 3

Area = 1 x 24, 2 x 12, 4 x 6, 8 x 3, 24, 1

The dimension of the parallelogram are 1 x 24, 2 x 12, 4 x 6, 8 x 3, and 24 x 1.

Answer: y=2x+7

Step-by-step explanation:

The og equation to get to the equation is y=mx+b. M=slope & B=y intercept

Lets first pick 2 points to find the slope (the formula is y2-y1/x2-x1). After using the formal, I got my slope as 2. Now I could say y=2x+b. Now to find the y intercept, the x point should be 0 because these are on going lines (you could tell by the infinite arrows) meaning there is no starting point. I got my y intercept as 7. Now, I know that y=2x+7.

Answer:

[tex]4 \frac{3}{28}[/tex]

Step-by-step explanation:

First, let's turn these mixed fractions to regular fractions to make multiplying easier:

3 2/7 = 2/7 + 21/7 = 23/7

1 1/4 = 1/4 + 4/4 = 5/4

Then multiply:

[tex]\frac{23}{7}*\frac{5}{4} = \frac{( 23 * 5 ) }{(7*4)} =\frac{115}{28}[/tex]

This fraction cannot be simplified, so let's turn it into a mixed fractions:

[tex]\frac{115}{28} =4\frac{3}{28}[/tex]

Answer:

Step-by-step explanation:

I don't do this question the same way as it is done in the classroom, but I will get you the right answer

Let the middle number = x

Let the smallest number = x - 2

Let the largest number = x + 2

x - 2 + x + x + 2 = 315             Combine like terms. The 2s cancel

3x = 315                                  Divide by 3

x = 105

So the middle number is 105

The smallest number is   103

The largest number is     107

Total                                  315

This method cuts out at least one step. It works best with an odd number of terms. If you have an even number, you have to use the more traditional method.
