A circle has a radius that measures 9 centimeters what is the area of the circle to the nearest tenth use pie 3.14​

Answer:

Height: 6.7         Length: 22

Step-by-step explanation:

Use Soh (sin(angle)=[tex]\frac{opposite}{hypotenuse}[/tex]) Cah (cos(angle)=[tex]\frac{adjacent}{hypotenuse}[/tex]) Toa (tan(angle)=[tex]\frac{opposite}{adjacent}[/tex])

Height:

You'd use sin so the equation is sin17=x/23 which is equal to (rounded) 6.7

Length:

You'd use cos so the equation is cos17=y/23 which is equal to (rounded) 22

*You always need to use a calculator when using sin, cos, and tan*

*SohCahToa is an easy way to remember the equations!*

Answer:

Mass of blackcurrants = 750 gram

Total conserve = 1,050 gram

Step-by-step explanation:

Given:

Mass of redcurrants = 300 gram

Blackcurrants : Redcurrants = 5 : 2

Find:

Mass of blackcurrants

Total conserve

Computation:

Mass of blackcurrants = 300 x (5/2)

Mass of blackcurrants = 750 gram

Total conserve = Mass of blackcurrants + Mass of redcurrants

Total conserve = 750 + 300

Total conserve = 1,050 gram

Answer: y = 0.4x in desmos

Step-by-step explanation:

Answer:

Not applicable.

Step-by-step explanation:

You could use Desmos as another person answered. However, if you are graphing by hand, simply choose two points and draw a straight line between them.

For example, you could pick x = 0 and x = 1. This gives you the two points (0, 0) and (1, 0.4)

Plot those two points and use a straight edge to draw a line between the two.

In case you are having trouble plotting (1, 0.4) since it is a decimal, try setting x = 5, you will get (5, 2) which should be much easier to graph.

Step-by-step explanation:

Recall that the first derivative of an equation gives us the SLOPE for the tangent line.

So first, we should find the first derivative.

[tex]\frac{dy}{dx} = 6 - 3x^2[/tex]

With the first derivative, we can solve for the SLOPE of the tangent line at (1,5).

Using x = 1.

[tex]slope = 6 - 3(1)^2[/tex]

A tangent line is a line. And has the form [tex]y = mx +b[/tex]

Where m is the SLOPE of the line. and b is the y-intercept.

To get to this equation, let's use the point-slope technique.

[tex]y-y_1 = m(x-x_1)[/tex]

[tex]y - 5 = m(x-1)[/tex]

Solve for slope, substitute it into this equation for m and solve. That is the equation of the tangent line at the point (1,5).

Answer:

w=13

Step-by-step explanation:

15+w=3w-11

+11           +11

26+w=3w

    -w   -w

26=2w

26/2=2w/2

13=w

Answer:

w =13

Step-by-step explanation:

15+w=3w−11

Collect like terms

15+11=3w−w

Simplify

26=2w

Divide both sides of the equationy 2

26/2=2w/2

Simplify

13=w

switch sides

w=13

Answer:

$360.

Step-by-step explanation:

Given that 5 liters of a solvent cost $ 72 per liter, to determine the value of 5 liters of solvent the following mathematical calculation must be carried out, consisting of multiplying the value per liter by the number of liters to be purchased:

72 x 5 = X

360 = X

Therefore, the 5 liters of solvent will have a cost of $ 360, that is, five times the value of the liter, which is $ 72.

Step-by-step explanation:

Answer:

P of white: 0.26

P of green: 0.39

Step-by-step explanation:

Assume the probability of a white pin is p.

Then the probability of a green pin is (3/2)p because their ratio is 3:2.

The sum of the probabilities must be 1.

0.1+(3/2)p+0.25+p=1

(5/2)p+0.35=1

(5/2)p=0.65

p=(2/5)(0.65)=0.26

(3/2)p=0.39

Answer:

78

Step-by-step explanation:

One simple way to solve problems like this is to multiply the number being divided in this case 6 and the end result in this case 13

so we do 6x13=78

The value 'd' obtained after solving the expression will be equal to 78.

The four basic mathematical operations are the addition, subtraction, multiplication, and division of two or even more integers.

Among them is the examination of integers, particularly the order of actions, which is crucial for all other mathematical topics, including algebra, data organization, and geometry.

As per the given equation in the question,

13 = d/6

d = 13 × 6

d = 78

Answer:

   f(x+1) = -21 -2x-4

Step-by-step explanation:

Explanation:-

Given that the function f(x) = -22-2x-1

                   f(x+1) = -22 -2( x+1) -1

                          = -22 -2x-2-1

                         = -2x -21 -4

                 f(x+1) = -21 -2x-4

Answer: Also according to Faraday's law of electromagnetic induction, changing magnetic field will create an electric field perpendicular to it's direction.

... That is why in an electromagnetic wave, electric and magnetic fields promote each other in directions perpendicular to themselves.

So they are perpendicular

Hope this helps.

Answer:

7

Step-by-step explanation:

We solve for x first.

So: 4x - 7 = 2x

Subtract 2x from both sides: 4x - 2x - 7 = 2x - 2x

2x - 7 = 0

Add 7 to both sides: 2x - 7 + 7 = 0 + 7

2x = 7

Divide by 2: [tex]\frac{2x}{2}[/tex] = [tex]\frac{7}{2}[/tex]

x =  [tex]\frac{7}{2}[/tex]

Now, we substitute x for  [tex]\frac{7}{2}[/tex] like this:

2 ( [tex]\frac{7}{2}[/tex]) = 7
