What is the product of the binomials (4a – 1) and (2b + 3)?A=18ab – 3
B=8a2b2 + 10ab – 3
C=6ab + 7a – 2b – 3
D=8ab + 12a – 2b – 3

Answers

Answer 1
Answer: Multiplying binomials can be done by distributing the first term of binomial 1 to the second binomial and then adding it to the product of the distribution of the second term of binomial 1 to the second binomial. This is shown below:

(4a - 1)(2b + 3) = 8ab + 12a - 2b - 3

From the choices, the correct answer is D.

What is the length of AC ? Round to the nearest tenth.10.5 m

Answers

The length of AC is equal to 10.5m

Data;

  • AC = ?
  • BC = 15m
  • Angle = 55 degrees

Trigonometric Ratio

To solve this problem, we have to apply trigonometric ratioSOHCAHTOA here;

Since we have the value of opposite side, angle and we are looking for the adjacent, we can use tangent of the angle to find AC
tan\theta = (opposite)/(adjacent)

Let's substitute the values and solve for AC

tan 55 = (15)/(AC) \nAC = (`15)/(tan55) \nAC = 10.5m

From the calculations above, the length of AC is equal to 10.5m

In this right triangle, side AC is adjacent to the reference angle we were given.  That's our unknown.  The other side is the side opposite the reference angle, so we need a trig ratio that relates the side adjacent to the side opposite which is tangent.  Setting up our ratio we have this: tan(55)= (15)/(x) and x= (15)/(tan(55)).  Do that on your calculator to find that side AC (x) = 10.5, first choice above.

I need help with this math question on my study guide!Sadly, I do not remember how to do this and I would greatly appreciate any help you can offer.

Sadly is right.  You must have practiced this stuff in middle school
until it was coming out of your ears.  Fortunately, you have a chance
to relearn it now.  You should do that ... it'll be important in any math
course you ever take.

'm' is the slope of the line on the graph.

The slope is

                (the change in 'y' between any two points on the line)
divided by
               (the change in 'x' between the same two points).

You can choose any two points on the line, and the slope is always the same.

To make it easy, look at the two points on this graph where the line crosses
the x-axis and the y-axis.

Going between these two points ...
-- the line goes up, from  y=0  to  y=4.  The change in 'y' is  4 .
-- the line goes to the right, from  x=-2  to  x=0.  The change in 'x' is  2 .

           'm' = the slope  =  (4)/(2)  =  2 .

The  "y-intercept"  is the place where the line crosses the y-axis.
On this graph, that's the point where  y=4 .

The equation of EVERY straight line on ANY graph is:

                 Y  =  (the slope) times 'x'  +  (the y-intercept) .

So the equation of THIS line on THIS graph is

                 Y = 2x + 4 .
 

Write in vertex form:

y = x2 - 4x - 1

On Monday at the county fair , Jared played a game and won 75 tickets . On Tuesday , he won 105 tickets on Wednesday , he won 127 tickets , but the spent 250 of them on a prize . How many more tickets does Jared need to win a prize that costs 150 tickets ?

Answers

Answer: 93

Step-by-step explanation:

75+105+127= 307

307-250= 57

150-57= 93 (57 + 93 = 150)

What is the domain of g?

Answers

Answer:

x≥ -3

Step-by-step explanation:

The domain is the values that x can take

g(x) = sqrt( x+3)

This must be greater than or equal to zero

x+3  must be greater than or equal to zero

x must be greater than or equal to -3

x≥ -3
