True or False!!!! The measure of a tangent-tangent angle is twice the difference of the measures of the intercepted arcs.
lozanna [386]

answer : False

The measure of a tangent-tangent angle is one - half the difference of the measures of the intercepted arcs.

The diagram is attached below

AB  and BC are the two tangents

By exterior angle theorem

 ∠3 = ∠2 + ∠4

So   ∠2 = ∠3 - ∠4

Now we find angle 3  and 4, we know when a chord and tangent intersect at a point then the measure of angle is one half of measure of intercepted arc

∠3 = \frac{1}{2} * arc(ADC)

∠4 = \frac{1}{2} * arc(AC)

 ∠2 = ∠3 - ∠4

 ∠2 = \frac{1}{2} * arc(ADC)  -  \frac{1}{2} * arc(AC)

∠2 = \frac{1}{2} ( arc(ADC) - arc(AC))

The measure of a tangent-tangent angle is one half the difference of the measures of the intercepted arcs.

If f(x) = 3x2 + x - 5, find f(4). Show your steps.
Flura [38]

Answer:

f(4)=47

Step-by-step explanation:

To find the answer, replace the x’s in the equation with 4. This would make the equation 3(4)^2 + 4 - 5. According to PEMDAS, you would first raise 4 to the power of 2 (16) then multiply it by 3 (48). This makes the equation 48 + 4 - 5. You just need to add and subtract from here. 48+4=52. 52-5=47

Simplify. Rewrite the expression in the form 5^n<br>(5^3)^2=<br>​
Temka [501]

Answer:

5^12

Step-by-step explanation:

index notation rules states that when there is a power inside AND outside the brackets, they shall multiply together. hence, we will multiply 3 and 2 so we will get 6 and thus the answer will be 5^6. Sike, that's not the answer, we forgot to multiply 5 with that power too... so we will get 25^6 because same power (outside brackey) will affect everything inside...

now after we got 25^6, we need to simplify it to get 5^n ....

so as we know 5^2 is 25, we can do this,

(5^2)^6 so we will multiply the powers to get

5^12 which is your answer :)
