A study showed 64% of those surveyed prefer coke to pepesi. If 275 people were surveyed how many said they prefer coke

Answer:

Step-by-step explanation:

The first step is to find the slope of the tangent line. To do that, we need to find the derivative of f(x):

f(x) = sin(x) + 2cos(x)

f'(x) = cos(x) - 2sin(x)

Now we can find the slope of the tangent line at x=0 by plugging in x=0 into f'(x):

f'(0) = cos(0) - 2sin(0) = 1

Therefore, the slope of the tangent line at x=0 is 1.

Next, we need to find the y-coordinate of the point on the graph where x=0. To do that, we simply plug in x=0 into f(x):

f(0) = sin(0) + 2cos(0) = 2

Therefore, the point on the graph where x=0 is (0, 2).

Now we can use the point-slope form of the equation of a line to find the equation of the tangent line:

y - y1 = m(x - x1)

where m is the slope and (x1, y1) is the point on the line. Plugging in m=1 and (x1, y1) = (0, 2), we get:

y - 2 = 1(x - 0)

Simplifying, we get:

y = x + 2

Therefore, the equation of the tangent line is y = x + 2.

Answer:

The equation of the tangent line at x = 0 can be found by differentiating the function f(x) and using the point-slope form of a line.

The derivative of f(x) is f'(x) = cos(x) - 2sin(x). Substituting x = 0 into f'(x) gives f'(0) = cos(0) - 2sin(0) = 1 - 0 = 1.

Therefore, the equation of the tangent line is y = 1x + b, or y = x + b.

To find the value of b, we can plug in x = 0 and y = f(0) = sin(0) + 2cos(0) = 2 into the equation. Solving for b, we get 2 = 0 + b, so b = 2.

Therefore, the slope-intercept equation of the line tangent to the graph of y = f(x) at the point (0,2) is y = x + 2.

The factor of the expression x² + 3x - 4 will be (x + 4) and (x - 1). And the variable 'x' represents the length of the rectangle.

The area of the rectangle is the multiplication of the two different sides of the rectangle. Then the rectangle's area will be

Area of the rectangle = L × W square units

Let 'x' be the length of the rectangle. Then the width will be (x - 5). Then the factors of the expression is given as,

A = x² + 3x - 4

A = x² + 4x - x - 4

A = x(x + 4) - 1(x + 4)

A = (x + 4) · (x - 1)

Answer: 40 fluid ounces is approximately equal to 1182.94 milliliters.

Step-by-step explanation:

A fluid ounce (oz) is a unit of volume used in the United States and some other countries, while milliliters (ml) are used in the metric system. To convert ounces to milliliters, we can use the conversion factor of 29.5735 ml per fluid ounce.

So, 40 fluid ounces is equal to:

40 oz * 29.5735 ml/oz = 1182.94 ml

Therefore, 40 fluid ounces is approximately equal to 1182.94 milliliters.

The QS would be QS = PQ(1 + PQ/13)

What are the sides and angles of a parallelogram?

S = (n 2) 180°, where 'n' specifies the number of sides in the polygon, can also be used to determine this.

Since PQRS is a parallelogram, opposite sides are parallel and equal in length. Therefore, we can say that PQ = SR and QS = PR.

If QX = 13, then we can use the fact that PQRS is a parallelogram to find the length of QS. We can draw a line segment from Q that is parallel to SR, and call the point where this line segment intersects PS as Y. This forms two triangles, QXY and QSR, which are similar because they share an angle and have parallel sides.

By the properties of similar triangles, we can set up a proportion:

QY/QX = QS/SR

Since QY is the same as PS, we can substitute PQ + QY for PS:

(QX + PQ)/QX = QS/SR

Substituting the value of QX and recognizing that PQ = SR, we get:

(13 + PQ)/13 = QS/PQ

Simplifying this equation, we get:

1 + PQ/13 = QS/PQ

Multiplying both sides by PQ, we get:

PQ + (PQ^2/13) = QS

Since PQ = SR and PQRS is a parallelogram, we know that SR = PQ, so we can substitute PQ for SR:

QS = PQ + (PQ^2/13)

Simplifying further, we get:

QS = PQ(1 + PQ/13)

Therefore, The QS would be QS = PQ(1 + PQ/13)

From trigonometric ratios, the value of x and y are 11 [tex]\sqrt{3}[/tex] and 11, respectively.

A triangle is classified as a right triangle when it presents one of your angles equal to 90º.  The greatest side of a right triangle is called the hypotenuse. And, the other two sides are called legs.

The math tools applied for finding angles or sides in a right triangle are the trigonometric ratios or the Pythagorean Theorem.

It’s easy all u have to do is add the 95% and 15%

And when u get the answer u add it with 1.10$ and boom u subtract the number and u get 24%.

Answer: $1.80 and $11.40

Step-by-step explanation:

We know that Chris was short on cash by $1.20, but we need to create an equivalent percentage.

95% + 15% = 110% (how much does it cost)

110% - 110% (how much he had) = 10% (amount short) = $1.20

10% = $1.20

100% (how much he had) = $12.00

Mouse = 95% of $12.00 (how much he had) = $11.40

Mouse pad = 15% of $12.00 (how much he had) = $1.80

Check your work:

$1.80 (Mouse pad) + $11.40 (Mouse) = $13.20

$13.20 - $12.00 = $1.20 (amount short)

An equation of the line that satisfies the given conditions is x = 2y + 13.

To find the equation of the line that passes through the point (-9, -11) and is perpendicular to the line passing through (-6, 1) and (-2, -1), we can use the slope-point form of a line.

First, we find the slope of the line passing through (-6, 1) and (-2, -1). The slope of this line can be found using the formula:

m = (y2 - y1) / (x2 - x1)

where (x1, y1) and (x2, y2) are the coordinates of the two points.

Plugging in the values, we have:

m = (-1 - 1) / (-2 - (-6)) = -2 / 4 = -1/2

The slope of a line perpendicular to this line has a negative reciprocal, so the slope of the line through (-9, -11) that is perpendicular to this line is 1/2.

Next, we use the point-slope form of a line to find the equation of the line:

y - y1 = m (x - x1)

where (x1, y1) is a point on the line and m is the slope.

Plugging in the values, we have:

y - (-11) = 1/2 (x - (-9))

Expanding and simplifying, we get:

y + 11 = 1/2 (x + 9)

Multiplying both sides by 2, we get:

2y + 22 = x + 9

Subtracting 9 from both sides, we get:

2y + 13 = x

So, the equation of the line that satisfies the given conditions is:

Answer:

v = 1.165

Step-by-step explanation:

To find the value of v in the equation 0.4 = 0.167 + 0.2v, we can isolate v by subtracting 0.167 from both sides:0.4 - 0.167 = 0.2v0.233 = 0.2vNext, we can divide both sides by 0.2 to find the value of v:0.233 / 0.2 = 0.2v / 0.2v = 0.233 / 0.2v = 1.165So the value of v is 1.165.In conclusion, by subtracting 0.167 from both sides of the equation and dividing both sides by 0.2, we found that the value of v is 1.165.

Answer: The value of v that satisfies the equation 0.4 = 0.167 + 0.2v is 1.165.

Step-by-step explanation:

To find the value of v in the equation 0.4 = 0.167 + 0.2v, we can isolate v by subtracting 0.167 from both sides:

0.4 - 0.167 = 0.2v

0.233 = 0.2v

Next, we can divide both sides by 0.2 to solve for v:

0.233 / 0.2 = 0.2v / 0.2

v = 1.165

So, the value of v that satisfies the equation 0.4 = 0.167 + 0.2v is 1.165.

The least polynomial that contains the roots - 6, 0, 3 - √5 is equal to y = x⁴ - 5 · x³  - 2 · x² + 4 · x.

In this problem we must determine a polynomial function that contains the following roots: - 6, 0, 3 - √5. By quadratic formula we understand the quadratic polynomial may contain two roots of this kind: x₁ = α + β and x₂ = α - β. Therefore, the complete set of roots of the least polynomial is:

x₁ = - 6, x₂ = 0, x₃ = 3 - √5, x₄ = 3 + √5

And the factor form of the least polynomial is:
