2 3/4. Three halves and four make five and a half. Two fourths is the same as a half . You want half of five and a half which is two and three quarters.

Solve sec2theta + tantheta - 3 =0 for 0

Serhud [2]

Answer:

Ф = $\frac{\pi }{4} ,\frac{5\pi}{4}$

Step-by-step explanation:

It is a bit difficult to input the work here, so I uploaded an image

First we can use the trig identities to change sec²(Ф) to tan²(Ф) + 1
Then we can combine like terms
Then we can factor this as a polynomial function
Then we can set each term equal to zero and solve for Ф
The first term tan(Ф) - 2 = 0 has no solution because tan(Ф) ≠ -2 anywhere
The second term tan(Ф) - 1 = 0 has two solutions of $\frac{\pi}{4}$ and $\frac{5\pi}{4}$ so these are the solutions to the problem

Applying the Procedure

Verizon [17]

Answer:

15 Square Inches

Step-by-step explanation:

Volume of the cone=40 cubic inches

Height of the cone=8 Inches

<u>Step 1:</u> Applying the formula for the volume of a cone

Volume of a Cone $=\frac{1}{3}\pi r^2 h=\frac{1}{3} X $Base Area X Height$

<u>Step 2:</u> Substituting values for the variables

$40=\frac{1}{3} X $Base Area X 8$

<u>Step 3:</u> Simplifying the right side

$40=\frac{8}{3} X $Base Area$

<u>Step 4:</u> Multiplying by the reciprocal

$40X\frac{3}{8}=\frac{8}{3} X\frac{3}{8} X $Base Area\\$

<u>Therefore, Base Area of the Cone=15 Square Inches</u>

PLS ANSWER: What is the monomial if a cube of a monomial is: 1/8 a^27

Katarina [22]

Answer:

$\frac{a^{9} }{2}$

Step-by-step explanation:

A monomial is a type of polynomial that has only one term and when there are two terms in the polynomial then it is called binomial.

Say for example (ax) is a monomial and (ax + b) is a binomial.

In our case the cube of a monomial is $\frac{a^{27} }{8}$

Therefore, the monomial will be $\sqrt[3]{\frac{a^{27} }{8}} =\frac{a^{9} }{2}$ (Answer)
