Answer: Choice A

m = undefined

point (-2,5)

==================================================

Explanation:

The equation x = -2 describes a vertical line in which every point on this line has x coordinate -2. Two points on this line are (-2,0) and (-2,1)

Another point on this line is (-2,5) since this also has x coordinate -2.

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

All vertical lines have undefined slope.

Let's pick two points such as (-2,0) and (-2,1) and find the slope through them

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

m = (1-0)/(-2-(-2))

m = (1-0)/(-2+2)

m = 1/0

m = undefined, since we cannot divide by zero.

a) The distance from point P to the pole  is: 6.2 m

b) The height of the Pole is: 6.2 m

The triangle attached shows us the triangle formed as a result of the given word problem about angle of elevation and distance and height.

Now, we are given that:

The angle of elevation of the top of the pole =  45°

Angle of elevation of the top of the pole = 58°.

|PQ|= 10m

a) PR is distance from point P to the pole and using trigonometric ratios, gives us:

PR/sin 58 = 10/sin(180 - 58 - 45)

PR/sin 58 = 10/sin 77

PR = (10 * sin 58)/sin 77

PR = 8.7 m

b) P O can be calculated with trigonometric ratios as:

P O = PR * cos 45

P O = 8.7 * 0.7071

P O = 6.2 m

Now, the two sides of the isosceles triangle formed are equal and as such:

R O = P O

Thus, height of pole R O = 6.2 m

Answer:b

Step-by-step explanation:

Using the z-distribution, the 95% confidence interval of the population mean is: (17.5, 24.5).

The confidence interval is:

\(\overline{x} \pm z\frac{\sigma}{\sqrt{n}}\)

In which:

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

For this problem, the other parameters are:

\(\overline{x} = 21, \sigma = 26.8, n = 225\)

Hence the bounds of the interval are:

\(\overline{x} - z\frac{\sigma}{\sqrt{n}} = 21 - 1.96\frac{26.8}{\sqrt{225}} = 17.5\)

\(\overline{x} + z\frac{\sigma}{\sqrt{n}} = 21 + 1.96\frac{26.8}{\sqrt{225}} = 24.5\)

The interval is: (17.5, 24.5).

Answer:

(a) The function has a minimum value

(b) The minimum value is 2

Step-by-step explanation:

(a)Currently y = x^2 + 4x + 6 is in standard form, whose general equation is

y = ax^2 + bx + c.  

We know that for our function a = 1.

Thus, y = x^2 + 4x + 6 must have a minimum value.

(b) Whenever a problem asks for the minimum value, it's asking for the y-coordinate of the minimum.

Step 1:  First we can find the x-coordinate of the minimum using the equation -b/2a from the quadratic formula.  

Plugging in 4 for b and 1 for a, we get:

x-coordinate of minimum = -4 / 2(1)

x-coordinate of minimum = -4 / 2

x-coordinate of minimum = -2

Step 2:  Now we can plug in -2 for x in the quadratic function.  The result will be our minimum value:

f(-2) = (-2)^2 + 4(-2) + 6

f(-2) = 4 - 8 + 6

f(-2) = -4 + 6

f(-2) = 2

Thus, the minimum value of the quadratic function is 2.

Step-by-step explanation:

Im pretty sure at least

Step-by-step explanation:

you mixed an 8% and a 12% solution together.

so, you get (8%×mass1 + 12%×mass2)/((mass1 + mass2)/2) as resulting % of the combined solution.

since the result is 10%, which is precisely the arithmetic middle

(8 + 12)/2

we see that mass1 = mass2.

in other words : the same quantity (mass) of the 8% solution and the 12% solution was mixed together.

so, 760g = 2×mass

=>

mass = 380g

380g of the 8% solution and 380g of the 12% solution were mixed together.

What are the zeros of the function algebraically?

The zeros of a function are the points at which the function's value is zero. These are obtained algebraically by setting the function to zero and solving the quadratic.

We have,

f(x) = -25x⁴ + 9x²

= (25 • (x⁴)) -  32x²

= (5)²x⁴ -  (3)²x²

= 25x⁴ - 9x²

= x² • (25x²- 9)

25x² - 9

  A difference of two perfect squares,  A2 - B2  can be factored into  (A+B) • (A-B)

25  is the square of  5

9 is the square of 3

x²  is the square of  x¹

Step-by-step explanation:

Correct on E2020!

The best decision to purchase a old car is cheaper compare to new car as per the total cost for each scenario over three years.

Compare the total costs of keeping his old car versus buying a new car, Manny needs to consider all the costs involved.

These include the cost of gas, the cost of maintenance and repairs, and the cost of purchasing the new car.

First, calculate the total cost of keeping his old car for three years.

Gas Cost,

Manny drives 190 miles per week,

which is approximately 9,880 miles per year 190 miles x 52 weeks.

With his old car's fuel efficiency of 18 miles per gallon,

He will use approximately 549 gallons of gas per year 9,880 miles ÷ 18 mpg.

At the current gas price of $ 2.9 per gallon, his annual gas cost will be $ 1,593 (549 gallons x $ 2.9 per gallon).

Over three years, his total gas cost will be $ 4,779.

Maintenance and Repairs Cost,

Manny's old car needs an average of $ 770 per year in maintenance and repairs.

Over three years, his total maintenance and repairs cost will be $ 2,310.

Total Cost of Keeping His Old Car,

Adding the gas cost and the maintenance and repairs cost,

Manny's total cost of keeping his old car for three years will be $ 7,089.

Now let's calculate the total cost of buying the new car.

Cost of Purchasing the New Car,

The new car costs $ 6,500, which he will pay over three years.

This works out to a monthly payment of approximately $ 181.94.

Gas Cost,

With the new car's fuel efficiency of 32 miles per gallon,

Manny will use approximately 309 gallons of gas per year (9,880 miles ÷ 32 mpg).

At the current gas price of $ 2.9 per gallon,

His annual gas cost will be $ 897.10 (309 gallons x $ 2.9 per gallon).

Over three years, his total gas cost will be $ 2,691.30.

Maintenance and Repairs Cost,

The new car will only require an average of $ 10 per month for general maintenance.

Over three years, his total maintenance and repairs cost will be $ 360.

Total Cost of Buying the New Car,

Adding the cost of purchasing the new car, the gas cost, and the maintenance and repair cost

= 6500 + 2691.30 + 360

=$9551.30

$9551.3 > $7089

Total cost of new car > Total cost of old car.

The linear function that has the same y-intercept as the given graph is the equation y = -2x + 10, corresponding to option 3.

To determine the linear function with the same y-intercept as the graph, we need to find the equation of the line passing through the points (3, 4) and (5, 0).

First, let's find the slope of the line using the formula:

slope (m) = (change in y) / (change in x)

m = (0 - 4) / (5 - 3)

m = -4 / 2

m = -2

Now that we have the slope, we can use the point-slope form of a linear equation to find the equation of the line:

y - y1 = m(x - x1)

Using the point (3, 4) as our reference point, we have:

y - 4 = -2(x - 3)

Expanding the equation:

y - 4 = -2x + 6

Simplifying:

y = -2x + 10

Now, let's check the given options to find the linear function with the same y-intercept:

Option 1: The table with x-values (-3, -1, 1, 3) and y-values (-4, 2, 8, 14)

The y-intercept is not the same as the given line. So, this option is not correct.

Option 2: The table with x-values (-4, -2, 2, 4) and y-values (-26, -18, -2, 6)

The y-intercept is not the same as the given line. So, this option is not correct.

Option 3: The table with x-values (-5, -3, 3, 5) and y-values (-15, -11, 1, 5)

The y-intercept is the same as the given line (10). So, this option is correct.

Option 4: The table with x-values (-6, -4, 4, 6) and y-values (-26, -14, 34, 46)

The y-intercept is not the same as the given line. So, this option is not correct.

Therefore, the linear function that has the same y-intercept as the given graph is the equation y = -2x + 10, corresponding to option 3.
