Answer:

Hi there!

The answer to this question is right.

Step-by-step explanation:

Right Angle: 90 degrees

Segments WA and BM are perpendicular to each other so angle MBW is a right angle.

Point N is located at (-2, 4) on the coordinate plane. Point N is reflected over the y

Alona [7]

Answer:

(2,4)

Step-by-step explanation:

It's reflected over the y axis so it would still have the same y value but the x value will be positive instead of negative

The point is (2,4)

Arrange the functions in ascending order, starting with the function that eventually has the least value and ending with the fun

natali 33 [55]

The main factor when x values are high is the nature of the function. For example, polynomial functions intrinsically grow slower than exponential functions when x is high. Also, the greater the degree of the polynomial, the more the function grows in absolute value as x goes to very large values.

In specific, this means that our 2 exponential functions grow faster than all the other functions (which are polynomial) and thus they take up the last seats. Also, 7^x grows slower than 8^x because the base is lower. Hence, the last is 8^x+3, the second to last is 7^x.

Now, we have that a polynomial of 2nd degree curves upwards faster than a linear polynomial when x is large. Hence, we have that the two 2nd degree polynomials will be growing faster than the 2 linear ones and hence we get that they fill in the middle boxes. Because x^2+4>x^2, we have that x^2+4 is the 4th from the top and x^2 is the 3rd from the top.

Finally, we need to check which of the remaining functions is larger. Now, 5x+3 is larger than 5x, so it goes to the 2nd box. Now we are done.

What is the fourth law of exponents

fredd [130]

Answer:

The fourth law of exponents says that "any value other than zero brought to an exponent of zero is equal to one". ... However, zero to the zero gets an error with the calculator, thus any value other than zero brought to an exponent of zero is equal to one, this proves fourth law of exponents.

In the circle below, AD is a diameter and AB is tangent at A. suppose mADC=228. Find the measures of mCAB and mCAD. Type your nu

Tju [1.3M]

Answer:

m∠CAB = 66°

m∠CAD = 24°

Step-by-step explanation:

The given parameters are;

The measure of arc m $\widehat{ADC}$ = 228°

The diameter of the given circle = $\overline{AD}$

The tangent to the circle = $\underset{AB}{\leftrightarrow}$

The measure of m∠CAB and m∠CAD = Required

By the tangent and chord circle theorem, we have;

m∠CAB = (1/2) × m $\widehat{AC}$

However, we have;

m $\widehat{AC}$ + m $\widehat{ADC}$ = 360° the sum of angles at the center of a circle is 360°

∴ m $\widehat{AC}$ = 360° - m $\widehat{ADC}$

Which gives;

m $\widehat{AC}$ = 360° - 228° = 132°

m $\widehat{AC}$ = 132°

Therefore;

m∠CAB = (1/2) × 132° = 66°

m∠CAB = 66°

Given that $\overline{AD}$ is the diameter of the given circle, we have

The tangent, $\underset{AB}{\leftrightarrow}$ , is perpendicular to the radius of the circle, and therefore $\underset{AB}{\leftrightarrow}$ is also perpendicular to the diameter of the circle

∴ m∠DAB = 90° which is the measure of the angle formed by two perpendicular lines

By angle addition property, we have;

m∠DAB = m∠CAB + m∠CAD

∴ m∠CAD = m∠DAB - m∠CAB

By substitution, we have;

m∠CAD = 90° - 66° = 24°

m∠CAD = 24°
