X = 28°

we know this because the box shows that angle ABC is a 90° angle & we know that angle AB is 62°, so that means we have to do 90-62 which is 28. therefore, x = 28°.

Multiply and simplify. (3x+5)(2x2−3x+2) Enter your answer, in standard form, in the box.
Sveta_85 [38]

Answer:

6x^3+x^2-9x+10

Step-by-step explanation:

We have the product, (3x+5)(2x^{2}-3x+2).

On simplifying the product, we get,

(3x+5)(2x^{2}-3x+2)

i.e. 6x^3-9x^2+6x+10x^2-15x+10

i.e. 6x^3+x^2-9x+10

Thus, the standard form of the product (3x+5)(2x^{2}-3x+2) is 6x^3+x^2-9x+10.

I need help pls<br> 11+4b=8b-13<br> b=?
spin [16.1K]
With this, you need side A to equal side B. Your first step is to move the variable to one side. (I've also worked in out, and color coordinated the steps, so you can see better).

11 + 4b = 8b - 13 < let's subtract "4b" from the left side to get rid of it (we're subtracting because it is added on to left side). This will give us:

11 = 8b - 13 < we've subtracted "4b" from the left side, however what you do to one side of the equal sign, you must do to the other, so subtract "4b" from the right side as well. Once done, you should have this"

11 = 4b - 13 < we have "4b-13" because you can only work with like terms. 8b-4b=4b, and the 13 stays untouched.
 
Now let's work on isolating the variable. See how we have a -13 on the side with the variable? We don't want that, so we're going to add 13 to that side, to give us 0 and cancel it out. Remember, what you do to one side, you must do to the other, so add 13 to the 11 on the other side as well. This will give you 24, and your equation should now look like this:

24 = 4b < we're almost done, but the variable is not quite by itself yet. We need to get rid of the "4" in "4b". 4 in being multiplied to "b" so we need to do the opposite operation to cancel it out. We need that 4 to be a 1 because 1x=x. So, divide 4b by 4 to get 1b or just plain b. 

Remember, what you do to one side, you must do to the other, so divide 24 by 4 to get 6, and you're left with your answer.

Answer 6 = b 

Hope this helps!

What are the diameter and circumference of the unit circle? Answer using π.
sveticcg [70]

Answer:

Diameter = 2      Circumference = 2π

Step-by-step explanation:

The diameter of a circle is the radius*2 and the radius of a unit circle is 1 so the diameter is 2. The circumference of a circle is the diameter*π. Since you are allowed to express it in terms of π. Just leave it at 2π, though the actual value of π is approximately 3.14

A guy wire is attached to the top of a radio antenna and to a point on horizontal ground that 40 m from the base of the antenna.
frutty [35]

Answer:

The length of the wire is 76.19 m.

Step-by-step explanation:

It is given that a guy wire is attached to the top of a radio antenna and to a point on horizontal ground that 40 m from the base of the antenna.

It means base of the right angled triangle is 40 m.

The wire makes an angle of 58deg 20min with the ground.

1 degree = 60 min

Using this conversion convert the given angle in degree.

58^{\circ}20'=58^{\circ}\frac{20}{60}^{\circ}=58\frac{1}{3}^{\circ}=\frac{175}{3}^{\circ}

In a right angled triangle

\cos \theta=\frac{adjacent}{hypotenuse}

\cos (\frac{175}{3}^{\circ})=\frac{40}{hypotenuse}

0.525=\frac{40}{hypotenuse}

hypotenuse=\frac{40}{0.525}

hypotenuse=76.190

Therefore the length of the wire is 76.19 m.
