Answer 1

Answer: See explanation: 10, 1, 1, -7

Step-by-step explanation:

I'll assume you are working with Excel. The Product function multiplies all the cells given in the specified range. Here, those are cells A2 through A5. As presnted, this would be [10*5*0*(-7)] = 0, which is the value of cell B2. If we want cell B2 to be -70, we must change one or more of the numbers in cells A2 to A5.

Initial: 10, 5, 0, -7 B2=0

Change: 10, 1, 1, -7 B2 = -70

Other combinations are possible.

Which is the image of the point (9,-4) after a reflection about line y = 2 then translated along the vector <-2,4>?
A. (7,4)
B. (9,8)
C. (7,0)
D. (7,12)

Answers

Answer: Choice D. (7, 12)

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

Explanation:

Start at (9,-4). Move 6 units up to arrive at (9,2). This second point is on the horizontal mirror line of y = 2. We move another 6 units to get to (9,8).

Going from (9,-4) to (9,8) represents reflecting over the line y = 2.

Now apply the translation vector <-2,4> which says "shift to the left 2 units and shift up 4 units". That translation vector is the same as writing the rule [tex](x,y) \to (x-2,y+4)[/tex]

Applying that translation to the point (9,8) moves us to (7,12)

A package of 6 pairs of insulated gloves costs $38.94. What is the unit price of the pairs of gloves? The unit price is $ per pair of gloves.

Answers

Answer:

6.49

Step-by-step explanation:

6 pairs of insulated gloves cost $38.94

That means 6 x (price of one glove) = 38.94

Let's say the price of on glove = x

The equation is :

6x = 38.94

x = 38.94 ÷ 6 (divide all sides by 6)

x = 6 + (2.94 ÷ 6) (Splitting numbers to multiples of 6)

x = 6 + 0.4 + ( 0.54 ÷ 6) (Splitting numbers to multiples of 6)

x = 6 + 0.4 + 0.09 (Adding all sums)

x = 6.49

Each pair of gloves cost 6.49

Answer:

6.49

Step-by-step explanation:

Now, the unit price = Price per unit of the given item

How can you tell if an equation (for example, x=16+3y (don’t solve this)) will be represented by a straight line when graphed on a coordinate plane? Is there an easy way to tell or how do you figure that out?

Answers

Answer:

I know it is a straight line because I can convert it into standard or slope intercept form. An example of when something isn't a straight line is like y=|x|.

x=16+3y

-3y=-x+16

y=1/3x-16/3

An equation where y = whatever and the ALL the variables are to the power of 1, like yours, then the line will be straight.

If the variable looks like x^2 or something, then it will not be a straight line.

Answers

Only when b = 0 or k = 1.

If f(x) = mx + b, then

f (kx) = m (kx) + b = mkx + b

while

k f(x) = k (mx + b) = kmx + kb

The two expression are identical only if

kb = b ===> kb - b = 0 ===> b (k - 1) = 0 ===> b = 0 or k = 1

An object is thrown upwards with a speed of 20 m/s. After t seconds, its height can be solved using the formula h = 20t - 4.9t2 where h is the height and t is the time. After how many seconds is the object 19.6 meters high?

Answers

Step-by-step explanation:

h= 20t - 4.9t^2

when h=19.6m

19.6=20t - 4.9t^2

4.9t^2 -20t+19.6=0

solving quadratically

t= 1.64 seconds or t= 2.45 seconds

Which equation shows that the product of a square matrix A and its identity matrix I is A?

Answers

Answer:

Option B

Step-by-step explanation:

The multiplication process of matrices works by multiplying the first row of the first matrix by the first column of the second matrix. The same goes with the second row of the first matrix by the second column of the other matrix. Below is the solution why option B is the correct answer.

[tex]A = \left[\begin{array}{ccc}8&11\\13&5\\\end{array}\right][/tex]

[tex]B = \left[\begin{array}{ccc}1&0\\0&1\\\end{array}\right][/tex] ← This is the Identity Matrix.

The attached screenshot shows the solution of the multiplication process. In essence, if you multiply any matrix by the identity (Matrix B), you should end up with your original matrix. Thus, multiplying Matrix A by the Identity matrix results in the same values as Matrix A.

Therefore, the correct answer is B.

Step-by-step explanation:

Pls mark as brainliest

Answer:

-4(3r + 5)

Step-by-step explanation:

To factor -4 out of -12r + 20, we need to find out what are the factors that can be multiplied with -4 to get a product of -12r and 20.

To get a product of -12, we must multiply -4 by 3r.

And to get a product of 20, we must multiply -4 by -5.

Therefore, the correct answer is: -4(3r - 5)

The remaining 20 percent noncontrolling interest shares had an acquisition-date estimated fair value of $428,000. Seidels acquisition-date total book value was $1,700,000.
