Write an equivalent measure in yards to to 126 in.? 1 ft = 12 in.1 yd = 3 ft

1 answer:

7 0

1 yard=36 inches and 126 inches to yards would be 3.5 yards because 3ft equals 36 inches and 126 divided by 36 equals 3.5 to check to 3.5 multiplied by 36

What is the slope of the line that contains the point -6,-7 and -6,2

Masja [62]

We know that coordinates are labeled (x,y)
The formula to find slope is (Y2-Y1)/(X2-X1)
So (2- (-7))/(-6-(-6) undefined because the denominator is zero. The line looks like a vertical line at x=-6

If A is nonsingular, then (AT )-1 =(A-1) T . (a) Verify this theorem for 2 × 2 matrices

kipiarov [429]

Answer:

Verified

Step-by-step explanation:

Let the 2x2 matrix A be in the form of:

$\left[\begin{array}{cc}a&b\\c&d\end{array}\right]$

Where det(A) = ad - bc # 0 so A is nonsingular:

Then the transposed version of A is

$A^T = \left[\begin{array}{cc}a&c\\b&d\end{array}\right]$

Then the inverted version of transposed A is

$(A^T)^{-1} = \frac{1}{ad - cb} \left[\begin{array}{cc}a&-c\\-b&d\end{array}\right]$

The inverted version of A is:

$A^{-1} = \frac{1}{ad - bc}\left[\begin{array}{cc}a&-b\\-c&d\end{array}\right]$

The transposed version of inverted A is:

$(A^{-1})^T = \frac{1}{ad - bc}\left[\begin{array}{cc}a&-c\\-b&d\end{array}\right]$

We can see that

$(A^T)^{-1} = (A^{-1})^T$

So this theorem is true for 2 x 2 matrices

A bank is offering 2.5% simple interest on a savings account. If Jayden deposits $5000,

Ahat [919]

Answer:

$2250

Step-by-step explanation:

First, find how much more Jayden will get each month by doing 2.5% of 5000, or multiplying 0.025 * 5000 = $125 per month.

Then, since Jayden is leaving it there for 18 months, you can do 125 * 18 = 2250.

The interest he will earn is $2250

The World Equity Index function shown contains two valuation metrics for the S&P 500. The Verizon description page contains

Nikitich [7]

Answer: Verizon is less expensive than the S&P 500 on both a P/E and dividend yield basis.

Step-by-step explanation:

When a Price to Earnings ratio is relatively high this means that the Price of the security is high because investors believe the company has good prospects.

When a Dividend Yield is relatively low, this means that the dividends being declared are quite lower than the price because Dividend yield is dividends as a percentage of security price. Lower Dividend Yields therefore mean high security prices.

Looking at the Verizon Chart and the S&P 500 you see that Verizon P/E ratio is 11.71 while S&P is 19.01.

This means that the price of Verizon's is less than S&P 500.

Also notice that Verizon's Dividend yield is 4.09% while S&P 500's is 1.91% again signifying that Verizon is cheaper.

I have attached the full question.

Pls help

Karolina [17]

Answer:

Step-by-step explanation:

If we look at the right side of the equation we see that the y-intercept is 2, so we will place a point on (0,2).

Next, we look to see if the slope of the graph if positive or negetive, and to see what is the slope (2x).

Finally, we look at the inequality if it is greater than (>), less than (<), greater than or equal to (_>), or less than or equal to (<_).

*Note the following:

if < then the line is dotted and the shading will be under the line.

if > then the line is dotted and the shading will be above the line.

if <_ then the line is solid and the shading will be under the line.

if _> then the line is solid and the shading will be above the line.*

It is a lot of information if you look at it, but with practice it can be made easier.
