-2, -10,-50, -250 What Is The Ninth Term, The Fifth Term And What Is The Common Ratio? What Is A Rule

Answers

Answer 1
I can’t remember what a common ratio is but you keep multiplying by 5 so the ninth term would be −781,250

Answer:

x + 22x - 3 = 4 (5x) + 3 (x-1)

Step-by-step explanation:

x + 22x - 3  

23x - 3

20x + 3x - 3

5x + 15x + 3x - 3

5x (1 + 3) + 3 ( x - 1)

Which of the following trigonometric ratios are correct?

Answers

Hi there! In this problem, you should have the knowledge of three basic Trigonometric Ratio.

sinA = opposite/hypotenusecosA = adjacent/hypotenusetanA = opposite/adjacent

Now that we know three basic ratio. Let's check each choices!

sin50° = d/c

This choice is wrong because we focus on the 50° angle. When we focus on 50°, sin50° should be d/x and not d/c.

sin50° = c/x

This choice is also wrong because in ratio, it's cos50° that adjacent/hypotenuse.

tan50° = d/c

This choice is correct! As ratio states, tanA = opposite/adjacent.

tan50° = x/c

This choice is wrong. x/c is a reciprocal of cosine which is 1/cos. We call the reciprocal of cosine as secant or sec in short.

cos50° = x/d

This choice is wrong as x/d is a reciprocal of sine which is 1/sin. We call the reciprocal of sine as cosecant or cosec/csc in short.

cos50° = c/x

This choice is right by the ratio. Nothing really much to explain since we follow by ratio that is defined.

Answer

tan50° = d/ccos50° = c/x

Questions can be asked through comment.

Furthermore, tan also has its reciprocal form itself which is called cotangent also known as cot in short.

Hope this helps, and Happy Learning! :)

In the rectangle below, SU= 4x-2, RT = 5x-10, and m ZSVT= 84º.
Find RV and m ZVUR.
R
S
U
T

Answers

Answer:

RV = 15, ∠ VUR = 48°

Step-by-step explanation:

The diagonals of a rectangle are congruent , so

RT = SU , that is

5x - 10 = 4x - 2 ( subtract 4x from both sides )

x - 10 = - 2 ( add 10 to both sides )

x = 8

Then

RT = 5x - 10 = 5(8) - 10 = 40 - 10 = 30

The diagonals bisect each other , then

RV = 0.5 × 30 = 15

---------------------------------------------------------------

∠ RVU = ∠ svt = 84° ( vertical angles )

RV = UV ( diagonals are congruent and bisect each other )

Then Δ RVU is isosceles with base angles congruent , then

∠ VUR = [tex]\frac{180-84}{2}[/tex] = [tex]\frac{96}{2}[/tex] = 48°

A triangle has sides with lengths of 72 inches, 78 inches, and 30 inches. Is it a right triangle?

Answers

Right triangles cant be found with the lengths of the sides of the triangle it’s the degrees of the actual Angles within the triangle a right triangle has at least one 90 degree angle

Answer:

yes

Step-by-step explanation:

Using the converse of Pythagoras' identity.

If the square of the longest side is equal to the sum of the squares on the other 2 sides then the triangle is right.

longest side = 78 and 78² = 6084

72² + 30² = 5184 + 900 = 6084

Then the triangle is right

Answers

Answer: w = 2

Explanation: To find the slope of a line, we use the formula y = mx + b, where m is the slope and b is the y-intercept. Since there is a variable, w, we can use this formula: m = 7 + w.

We know that m, or the slope of the line, is 9. If we substitute the value of 9 into that equation... we should get 9 = 7 + w.

It's simple mathematics from here.

7 plus what is 9?? 2. That's your answer. If you need help with slope-intercept and rate of change WITHOUT variables (besides x and y, of course), feel free to let me know!!

Where did I get that 7?

Usually, we use the slope formula to find the slope of a line when we know two points on the line. But if we already know the slope of a line, we can use the slope formula to find a missing coordinate of a point on the line.

We will be using this formula: y - y₂ = m(x - x₁)

This equation is useful when we know:

one complete coordinate point (x₁, y₁)and the slope of the line (m)

and we want to find the other point.

(x₁, y₁) is the known point. In our example, it's (-7,-7).

(x, y), sometimes written as (x₂,y₂), is (-6, w) and represents the missing coordinate.

EXAMPLE (SEE IMAGE):

slope (m) = 3

y − y1 = m(x − x1)

We know m, and also know that (x1, y1) = (3,2), and so we have:

y − 2 = 3(x − 3)

That is a perfectly good answer, but we can simplify it a little:

y − 2 = 3x − 9

y = 3x − 9 + 2

y = 3x − 7

The figure above shows a store’s supply-demand graph for coffee makers. If the store sells $375 worth of coffee makers, which of the following is a valid possible price for them? a. $15 b. $25 c. $40 d. $55

Answers

answer:
b. $25

step-by-step explanation:
$375 / 15
25 coffee makers
$375 / 25
15 coffee makers
$375 / 40
9.375 coffee makers which makes no sense
$375 / 55
6.81818182 coffee makers which also makes no sense
coffee makers are usually over $20 so b makes the most sense here

The price of $25 is a valid possible price for coffee makers

What is a supply demand graph?

A supply demand graph is a graph that shows the relationship between the supply and the demand of an item

The worth of the coffee is given as:

Worth = $375

The valid price of the coffee is calculated using:

Price = Worth/n

Where n represents the number of unit coffee

Make n the subject.

So, we have:

n = Worth/Price

This gives

n = 375/Price

When Price = 15, we have:

n = 375/15 = 25

When Price = 25, we have:

n = 375/25 = 15

When Price = 40, we have:

n = 375/40 = 9.375

When Price = 55, we have:

n = 375/55 = 6.818

Ignore the decimal results

So, we have

n = 375/15 = 25

n = 375/25 = 15

At a price of $25, the coffee maker sells less coffee than at a price of $15.

This means that they sell less to earn more

Hence, the price of $25 is a valid possible price for them

Step-by-step explanation:

because the fractions have different denominators you have to multiply the denominators together to figure out what to change them too. but instead you can just figure out what the decimal for each is. 1/3 is 0.33, and 4/5 is 0.80. all you do is add these together to get 1.13. so now all you do is add 2+1.13 to get 3.13.
