Answer:

Step-by-step explanation:

In expanded form, the quadratic is ...

  (2x +1)(x +6) = 2x(x +6) +1(x +6) = 2x² +12x +x +6

  = 2x² +13x +6

Comparing this to ...

  Ax² +Bx +C

Answer:

[tex]Area = 90.03cm^2[/tex]

Step-by-step explanation:

Given

[tex]s_1 = 14.9[/tex]

[tex]s_2 = 14.7[/tex]

[tex]\theta = 124[/tex] --- angle in between

Required

The area of the plate

Since [tex]\theta = 124[/tex] is between [tex]s_1[/tex] and [tex]s_2[/tex]

The area is:

[tex]Area = \frac{1}{2} * s_1 * s_2 * \sin(\theta)[/tex]

[tex]Area = \frac{1}{2} * 14.9 * 14.7 * \sin(124.7)[/tex]

[tex]Area = \frac{1}{2} * 14.9 * 14.7 * 0.8221[/tex]

[tex]Area = 90.03cm^2[/tex]

Answer:

[tex]\cos(A) = \frac{60}{61}[/tex]

Step-by-step explanation:

Given

[tex]\tan(A) = \frac{11}{60}[/tex]

[tex]0 \le A \le 90[/tex] --- First Quadrant

Required

Find cos(A)

The tan of an angle is:

[tex]\tan(A) = \frac{Opposite}{Adjacent}[/tex]

and

[tex]\tan(A) = \frac{11}{60}[/tex]

By comparison:

[tex]Opposite = 11[/tex]

[tex]Adjacent = 60[/tex]

So, the hypotenuse is:

[tex]Hypotenuse^2 = Adjacent^2 + Opposite^2[/tex]

[tex]Hypotenuse^2 = 60^2 + 11^2[/tex]

[tex]Hypotenuse^2 = 3721[/tex]

Take square roots

[tex]Hypotenuse = \sqrt{3721[/tex]

[tex]Hypotenuse = 61[/tex]

The cosine of an angle is:

[tex]\cos(A) = \frac{Adjacent}{Hypotenuse}[/tex]

This gives:

[tex]\cos(A) = \frac{60}{61}[/tex]

Answer:

a) 8

b) 27

c) x+7

d) 5

Step-by-step explanation:

For a and b your are just adding 7

For c you are just writing the algebraic equation

For d you are just subtracting 7

Hope this helps!:)

Answer:

1. a. 8 years

   b. 27 years

   c. x+7 because x is an unknown value so it is x+7.

   d. 5 years old

Step-by-step explanation:

a, b, c, d it is the value they give you plus 7.

d. her sister is 5 years old because Britney is 7 years older than her. in this situation her sister is X years old, but they tell you what Britney's age is. so you do 12-7 because her sister is 7 years younger. 12-7= 5 so her sister is 5 years old. you can check this by doing 5+7, to get 12.

Answer:

There would be a 1/221 chance.

Step-by-step explanation:

So in a stack of cards, there are 52 total cards, 4 of which are 1's.

With this, you would have a 1/13 chance of picking up a card that's a 1 for the first picking, since 1/13 = 4/52.

Since this 1 card was picked and not put back by the second picking, the chance of picking up a card that is a one drops. With this, there is now a 3 / 51 chance that a 1 card is  picked up since this card was removed.

Now with combining these two probabilities, multiply them together:

1/13 * 3/51 = 3/663 ---> 1/221.

Step-by-step explanation:

it's just a guess but the other side of the triangle is 137 degrees

Answer:

B. Tangent

Step-by-step explanation:

Tangent always makes 90 degree angle with the radius. Now in triangle let's see if it's right angled triangle or not.

To confirm if it's a right angled triangle it should follow Pythagoras Theorem.

Which states square of hypotenuse = sum of squares of other two legs

[tex]12 {}^{2} + 16 {}^{2} = 20 { }^{2} \\ 144 + 256 = 400 \\ 400 = 400[/tex]

it proves that it's a right angled triangle. Hence AB is a tangent to circle.

Yes, line AB is tangent to the circle.

The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.

Since, Tangent always makes 90 degree angle with the radius.

Hence, in triangle we can see if it's right angled triangle or not.

Now, To confirm if it's a right angled triangle it should follow Pythagoras Theorem as;

12² + 16² = 20²

144 + 256 = 400

400 = 400

Which states square of hypotenuse = sum of squares of other two legs

it proves that it's a right angled triangle. Hence AB is a tangent to circle.

Hence, We can say that;

⇒ line AB is tangent to the circle.

Answer:

100cubic inches

Step-by-step explanation:

varies inversely

pv = k

Find the constant of variation:

volume of 180 cubic inches under a pressure of 5 pounds

5 * 180 = k

k = 900

volume if the pressure is increased to 9 pounds per square inch?

9v = 900

divide both sides by 9

v = 100

Answer:

B. 68°

Step-by-step explanation:

The interior angles of the right triangle from the figure given are:

<1, right angle (90°), and (180° - 158°)

m<1 + 90° + (180° - 158°) = 180° (sum of triangle)

m<1 + 90° + 22° = 180°

m<1 + 112° = 180°

m<1 + 112° - 112° = 180° - 112°

m<1 = 68°
