Answer:

\frac{\pi}{4},\frac{\pi}{2},\frac{\pi}{2}

Step-by-step explanation:

We know the relation between radian and degree

π radian = 180 degrees

So, we have

1^{\circ}=\frac{\pi}{180}

Using this relation, we convert all the angle which is in degree to radian.

45^{\circ}=\frac{\pi}{180}\times45\\\\=\frac{\pi}{4}

And 90 degrees in radian is equal to

90^{\circ}=\frac{\pi}{180}\times90\\\\=\frac{\pi}{2}

Therefore, in radian measure, the angles are

\frac{\pi}{4},\frac{\pi}{2},\frac{\pi}{2}

C is the correct option.

45, 45, 90

45 *π/180 = π/4
90 *π/180 =π/2

45, 45, 90 is the same as π/4, π/4, π/2

The area of the object with a shape of kite having diagonals of 14 inches and 10 inches is 70 in².

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more variables and numbers.

The area of kite = (product of diagonals)/2

Area of kite = (10 * 14) / 2 = 70 in²

The area of the object with a shape of kite having diagonals of 14 inches and 10 inches is 70 in².

Find the limit of the function by using direct substitution.
serg [7]

Answer:

Option a.

\lim_{x \to \frac{\pi}{2}}(3e)^{xcosx}=1

Step-by-step explanation:

You have the following limit:

\lim_{x \to \frac{\pi}{2}{(3e)^{xcosx}

The method of direct substitution consists of substituting the value of \frac{\pi}{2} in the function and simplifying the expression obtained.

We then use this method to solve the limit by doing x=\frac{\pi}{2}

Therefore:

\lim_{x \to \frac{\pi}{2}}{(3e)^{xcosx} = \lim_{x\to \frac{\pi}{2}}{(3e)^{\frac{\pi}{2}cos(\frac{\pi}{2})}

cos(\frac{\pi}{2})=0\\

By definition, any number raised to exponent 0 is equal to 1

So

\lim_{x\to \frac{\pi}{2}}{(3e)^{\frac{\pi}{2}cos(\frac{\pi}{2})} = \lim_{x\to \frac{\pi}{2}}{(3e)^{\frac{\pi}{2}(0)}\\\\

\lim_{x\to \frac{\pi}{2}}{(3e)^{0}} = 1

Finally

\lim_{x \to \frac{\pi}{2}}(3e)^{xcosx}=1

Convert 53 yards per hour into inches per day
marin [14]

1 yard = 36 inches.

53 yards per hour x 36 inches per yard = 1908 inches per hour.

1 day = 24 hours.

1908 inches per hour x 24 hours = 45,792 inches per day.
