Angle A is circumscribed about circle O.<br> What is the measure of
Naddika [18.5K]

Answer:

m\angle O = 134 \degree

Step-by-step explanation:

AC and AB are tangents to the circle with center O on points C and B respectively from point A.

Therefore

m\angle ACO=m\angle ABO=90\degree

m\angle CAB=46...(given) \degree

m\angle O = 360 \degree - (2 \times 90 \degree + 46 \degree) \\  \\ m\angle O = 360 \degree - (180 \degree + 46 \degree) \\  \\ m\angle O = 360 \degree - (226 \degree) \\  \\ m\angle O = 134 \degree\\  \\

StartFraction (negative 7) squared Over (negative 7) Superscript negative 1 EndFraction
Elan Coil [88]

Answer:

-343

Step-by-step explanation:

Given the expression:   \dfrac{(-7)^2}{(-7)^{-1}}

You will notice that the terms in the numerator and denominator have the same base (-7).

This makes it very easy to simplify by applying the division law of indices.

\dfrac{a^x}{a^y} =a^{x-y}

Therefore:

\dfrac{(-7)^2}{(-7)^{-1}}=(-7)^{2-(-1)}\\=(-7)^{2+1}\\=(-7)^3\\=-7 X -7 X -7\\=-343

julia-pushkina [17]

Answer:

About 68% (is that an answer choice?)

Step-by-step explanation:

In a normal distribution (a bell curve), about 68 percent of the data is in the range between one standard deviation below the mean to one standard deviation above.  If your mean is 27, and the standard deviation is 3, then one deviation below to one above would be 27 - 3  to 27 + 3, or 24 - 30.

Write an expression with a negative exponent that has a value between 0 and 1/2
aliya0001 [1]
<span>Exponent is a number used to express shorter equation; it is a number that says how many times you are going to multiply the base number.
</span><span>
Exponents have several laws, here are some:
=> x^1 = x
=> x^0 = 1
=> x^-1 = 1/x
=> x^m x^n = X^m+n
=> x^m/x^n = x^m-n

And since we were asked to write an expression with a negative exponent that has a value between 0 and ½
=> 2^ -2 = ½
