Step-by-step explanation:

-0.92 2.49

-5.62 9.76

Rise = 9.76 - 2,49 = 7.27

Run: -5.62 - (-0.92) = -4.7

Slope (Rise/Run) = (7.27.`-0.92) = -1.55

The line has the form:

y = 1.55x + b

We need to find a value of b that forces the line through both point, Use one of the points and solve for b. I'll use (-0.92, 2.49).

y = 1.55x + b

2.49 = 1.55(-0.92) + b

b = 2.49 - 1.426 = 1.064

The equation is y = 1.55x + 1.0

Answer:

No, she doesn't have enough varnish for all the floors.

Step-by-step explanation:

Area of the floor, A= 10x6-5x2=50 \(m^2\)

Since 5 m^2 required 1 liter of varnish.

So, the amount of varnish required for 1 \(m^2\) = 1/5= 0.2 liters.

The amount of varnish required for 50 \(m^2\) = 0.2X50=10 liters.

Now, as 1 tin has 2.5 liters of varnish.

So, the total amount of varnish available = 3x2.5=7.5 liters, which is less than the total requirement.

Hence, she doesn't have enough varnish for all the floors.

Integrating by parts, we have:

I x f''(x) dx = I x f'(x) f'(x) dx - I f'(x) x f'(x) dx

The value of the integral I x f''(x) dx when f(0) = 2, f(1) = 3, f'(0) = 2, f'(1) = 4 is 3.

Using the fact that f(0)=2 and f(1)=3, the left side of the equation evaluates to f(1)f'(1)-f(0)f'(0) = 3*4 - 2*2 = 8.

For the right side, we can evaluate the first term by substituting x=0 and x=1, which yields f'(1) - f'(0) = 4 - 2 = 2. For the second term, we can evaluate the integral as follows:

I f'(x) x f'(x) dx = I x2 f'(x)2 dx = x3 f'(x)2/30 = 13 f'(1)2/3 - 03 f'(0)2/3 = 22/3 - 0/3 = 4/3.

Substituting these values into the equation yields 8 = 2 - 4/3, which simplifies to 8 = 14/3. This implies that I=3.

Answer:

this question is a very simple. you should start with the biggest triangle then follow the steps to find each side of other triangles. THE ANSWER İS ROOT FORTY ONE

Step-by-step explanation:

these are all right-angled triangles. even the smallest one with the x side.

so, we need to apply Pythagoras to get the missing sides and finally x.

c² = a² + b²

c is the Hypotenuse, the baseline of the triangle opposite of the 90 degree angle. a and b are the legs of the triangle enclosing the 90 degree angle.

so,

52² = 48² + side1²

2704 = 2304 + side1²

400 = side1²

side1 = 20

20² = 12² + side2²

400 = 144 + side2²

256 = side2²

side2 = 16

13² = 5² + (larger part of side2)²

169 = 25 + (larger part of side2)²

144 = (larger part of side2)²

larger part of side2 = 12

that means the smaller part of side 2 = 16-12 = 4.

x² = 5² + 4² = 25 + 16 = 41

x = sqrt(41)

So, D is the right answer option.

Given:

For en exponential function f(a):

\(f(-3)=18\)

\(f(1)=59\)

To find:

The value of f(0).

Solution:

The general form of an exponential function is:

\(f(x)=ab^x\)          ...(i)

Where, a is the initial value and b is the growth/ decay factor.

We have, \(f(-3)=18\). Substitute \(x=-3,f(x)=18\) in (i).

\(18=ab^{-3}\)            ...(ii)

We have, \(f(1)=59\). Substitute \(x=1,f(x)=59\) in (i).

\(59=ab^{1}\)            ...(iii)

On dividing (iii) by (ii), we get

\(\dfrac{59}{18}=\dfrac{ab^{1}}{ab^{-3}}\)

\(3.278=b^{1-(-3)}\)

\(3.278=b^{4}\)

\((3.278)^{\frac{1}{4}}=b\)

\(1.346=b\)

Substituting the value of b in (iii).

\(59=a(1.346)^1\)

\(\dfrac{59}{1.346}=a\)

\(43.83358=a\)

\(a\approx 43.83\)

The initial value of the function is 43.83. It means, \(f(0)=43.83\).

Therefore, the value of f(0) is 43.83.

The value of the given expression is -1.

Given is an expression 1/4 (-4/1) (3/5) (-5/6) (-2) we need to simplify it,

Step-by-step explanation:

Answer:

When f(x)= 3x – 1 and g(x) = 7x + 6,

f(g(x)) = 21x + 17

and

g(f(x)) = 21x - 1

Step-by-step explanation:

Given:

f(x) = 3x - 1

g(x) = 7x + 6

To find f(g(x)), substitute the value of g(x) into f(x).

f(g(x)) = f(7x + 6)

Substitute variable.

f(7x + 6) = 3(7x + 6) - 1

Distribute the 3 inside the parenthesis.

f(7x + 6) = 21x + 18 - 1

Subtract 1 from 18.

f(7x + 6) = 21x + 17

Therefore, f(g(x)) is 21x + 17.

To find g(f(x)), substitute the value of f(x) into g(x).

g(f(x)) = g(3x - 1)

Substitute variable.

g(3x - 1) = 7(3x - 1) + 6

Distribute the 7 inside the parenthesis.

g(3x - 1) = 21x - 7 + 6

Add 6 to -7.

g(3x - 1) = 21x - 1

Therefore, g(f(x)) is 21x - 1.

Substituting u = x^(2/3x^6) in the integral ∫ (2x^3)(x^2/3x^6)^5 dx and arriving at the solution  3∫(x^3)(u^5) du.

To evaluate the integral ∫ (2x^3)(x^2/3x^6)^5 dx, we can simplify the expression by making the substitution u = x^(2/3x^6). This substitution allows us to transform the integral into a simpler form, making it easier to evaluate.

Let's make the substitution u = x^(2/3x^6). Taking the derivative of both sides with respect to x gives us du = (2/3x^6)(x^(-1/3)) dx. Simplifying this equation, we have du = (2/3)dx.

Now, we can rewrite the original integral in terms of u as follows:

∫ (2x^3)(x^(2/3x^6))^5 dx = ∫ (2x^3)(u^5) dx.

Using our substitution, we can also rewrite x^3dx as (3/2)du. Substituting these into the integral, we have:

∫ (2x^3)(x^(2/3x^6))^5 dx = ∫ (2x^3)(u^5) dx = 2∫(x^3)(u^5)dx = 2∫(x^3)(u^5)(3/2)du.

Simplifying further, we have:

∫ (2x^3)(x^(2/3x^6))^5 dx = 2(3/2) ∫ (x^3)(u^5) du = 3∫(x^3)(u^5) du.

Now, we can evaluate this integral with respect to u, which gives us a simpler expression to work with. Once we find the antiderivative of (x^3)(u^5) with respect to u, we can substitute u back in terms of x to obtain the final result.

2,735 yes votes

Step-by-step explanation:

First we have too determine the ratio of yes votes to the total number of votes.

We can rationalize thus

If there are 5 yes votes and 4 no votes, the total number of votes = 5+ 4 = 9

So 5/9th of the total votes are yes votes

If the total number of votes = 4923 , number of yes votes = 5/9 x 4923

= 2,735 yes votes       ANSWER

We can check to see if our reasoning is correct:

Total number of no votes = 4923 - 2735 = 2188

Yes votes to Nay votes = 2735 : 2188

As a fraction:
2735 / 2188 = 1.25

1.25 = 1 1/4 = 5/4 which is the ratio of yes to no votes and tallies with the question data

The surface with the given vector equation, r(s, t) = (s cos(t), s sin(t), s), is a circular cone.

The vector equation r(s, t) = (s cos(t), s sin(t), s) represents a surface in three-dimensional space. Let's analyze the equation to determine the nature of the surface.

In the equation, we have three components: s, cos(t), and sin(t). The presence of s indicates that the surface expands or contracts radially from a central point. The trigonometric functions cos(t) and sin(t) determine the angle at which the surface extends in the x and y directions.

By observing the equation closely, we can see that as s increases, the radius of the surface expands uniformly in all directions, while the height remains constant. This behavior is characteristic of a circular cone. The circular base of the cone is defined by s cos(t) and s sin(t), and the vertical component is determined by s.

Therefore, the surface described by the vector equation r(s, t) = (s cos(t), s sin(t), s) is a circular cone.

Think about what happens when you double a number.

You multiply it by 2. Since it's been doubles, we say is has had a 100% increase.

Likewise a 50% increase correlates to multiply by 1.5

Since we are trying to find the previous amount that experienced the increase, we divide by 1.5 to find the original amount because that amount*1.5 gives us 279.

Calling the original r, it is clear that 1.5r=279.

Solving for r, we find the original # of robberies to be 186.
