what are the coordinates of a point where graph of y=x2+3x+2 crosses the x axis

The graph with an equation y = 6x has a slope of 6. If the slope is changed to 0, the equation becomes y = 0.

A linear function is in the form:

y = mx + b

Where m is the slope (rate of change) and b is the y intercept

The graph with an equation y = 6x has a slope of 6. If the slope is changed to 0, the equation becomes y = 0.

Step-by-step explanation:

The value of the z statistic for the considered data is given by: Option C: 1.98 approximately.

If we're given that:

Then, we get:

[tex]z = \dfrac{\overline{x} - \mu}{s}[/tex]

If the sample standard deviation is not  given, then we can estimate (in some cases) it by:

[tex]s = \dfrac{\sigma}{\sqrt{n}}[/tex]

where [tex]\sigma[/tex] = population standard deviation

For this case, we're specified that:

Thus, the value of the z-statistic is evaluated as:

[tex]z = \dfrac{\overline{x} - \mu}{\sigma/\sqrt{n}} = \dfrac{93.5 - 92}{2/\sqrt{7}} \approx 1.98[/tex]

Thus, the value of the z statistic for the considered data is given by: Option C: 1.98 approximately.

We see that Triangle ABC is an isosceles triangle which means:

We see that Angle BCD and Angle BCA are on a straight line, which means that both of the angles' measures are equal to 180 degrees

    --> in equation form:

              Angle BCD + Angle BCA = 180

                118 + Angle BCA = 180

                         Angle BCA = 62 degrees

Since Angle BCA and BAC are equal, then Angle BAC or Angle A in this case is 62 degrees

Answer:

37.69

Step-by-step explanation:

There are 3 circles

Circle A ( radius = 6 cm )

Circle B ( radius = 4 cm )

Circle C ( radius = 2 cm )

the circumference of a circle is C = 2 Pi x r

from each circle we need half of the circumference

Circle A : P = 2pi x 6 / 2 = 6 pi

Circle B : P = 2pi x 4 / 2 = 4 pi

Circle C : P = 2pi x 4 / 2 = 2 pi

the perimetee of the shaded shape is = 6 pi + 4 pi + 2 pi = 12 pi = 37.69 cm

Answer:

(a) 3x + 4 = 2x + 1

3x - 2x = 1 - 4

x = -3

Step-by-step explanation:

To solve for 'X', you must move all 'x' to the left-hand side, as seen through the working out. To balance it, you move all the lone numbers without (constants) to the right. Remember: when you move values across the 'equals' sign, the sign of the value you are moving becomes switched. For example, if you're moving 3x + 1 = 0 and you wish to move 1 to the other side, it becomes 3x = 0 ( - 1).

15 cm^3 = 15 / 1×10^6 = 15×10^-6 m^3

Using the z-distribution, as we are working with a proportion, the 95% confidence interval for the proportion of consumers who would buy the product at it's proposed price is (0.3016, 0.3830).

A confidence interval of proportions is given by:

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which:

In this problem, we have a 95% confidence level, hence[tex]\alpha = 0.95[/tex], z is the value of Z that has a p-value of [tex]\frac{1+0.95}{2} = 0.975[/tex], so the critical value is z = 1.96.

179 out of 523 members indicated they would buy the new product at the proposed price, hence:

[tex]\pi = \frac{179}{523} = 0.3423[/tex]

Then the bounds of the interval are found as follows:

[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.3423 - 1.96\sqrt{\frac{0.3423(0.6577)}{523}} = 0.3016[/tex]

[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.3423 + 1.96\sqrt{\frac{0.3423(0.6577)}{523}} = 0.3830[/tex]

The possible turning point for the continuous function f(x) is (-2, -1)

A stationary point is called a turning point if the derivative changes sign (from positive to negative, or vice versa) at that point.

There are two types of turning point:

A local maximum, the largest value of the function in the local region. A local minimum, the smallest value of the function in the local region.

Given are the coordinates of a function,

We need to find the turning point of the same,

Since we know that the function of the graph is continuous, then (-2, -1) is the most likely turning point because at this point the function stops increasing and starts decreasing.

Hence, the possible turning point for the continuous function f(x) is (-2, -1)

Given:

Two are scuba diving in the water, below sea level. One is swimming on the surface, at sea level.

We know that the the region below sea level represented by negative integers and the region above sea level represented by positive integers.

Thus, if the scuba driver is on the surface then it neither negative nor positive.

So, it would be represented by zero.
