Answer:

The opposite side x is 7

Step-by-step explanation:

Step one

From the given expression in the picture

We can estimate x by applying the

SOH CAH TOA rule on the triangle

Since we have one side and one angle given

step two

From the given picture we have

We have θ and adjacent side given

Hence we need to apply

tan θ= opposite/adjacent =

Tan 35°=x/10

Step three

From 4 figure table or calculator

tan 35° is 0.7

0.7=x/10

x=0.7*10

x= 7

4. 469.2

Step-by-step explanation:

16.27/2 =8.135

8.135*15= 122.025

11.73 divided by 1/2= 23.46

23.46*20=469.2

What is the local minimum value of the function? (Round answer to the nearest hundredth) g(x)=x^4-5x^2+4

Serhud [2]

The local minimum of function is an argument x for which the first derivative of function g(x) is equal to zero, so:
g'(x)=0
g'(x)=(x^4-5x^2+4)'=4x^3-10x=0
x(4x^2-10)=0
x=0 or 4x^2-10=0
4x^2-10=0 /4
x^2-10/4=0
x^2-5/2=0
[x-sqrt(5/2)][x+sqrt(5/2)]=0

Now we have to check wchich argument gives the minimum value from x=0, x=sqrt(5/2) and x=-sqrt(5/2).
g(0)=4
g(sqrt(5/2))=25/4-5*5/2+4=4-25/4=-9/4
g(-sqrt(5/2))=-9/4
The answer is sqrt(5/2) and -sqrt(5/2).

You are choosing between two mugs. One has a base that is 5.5 inches in diameter and a height of 3 inches. The other has a base

zysi [14]

Mug 2 can hold the most as its volume is greater than that of mug 1

Step-by-step explanation:

To find out which mug holds more let us find the volume of each mug

As we know

Height of first mug =H1= 3 in

Diameter of first mug= D1= 5.5 in

Radius of first mug = R1= $\frac{5.5}{2}$

= 2.75 in

The volume of first mug M1 is V1

The formula used will be

V=πr2h

V1 will be equal to

$V1=\pi r_{1} 2 h_{1} \\V1= \pi (2.75) (2) (3)\\V1= 51.81$

V1 = 51.81

Similarly

As we know

Height of second mug = H2= 4 in

Diameter of second mug = D2 = 4.5 in

Radius of second mug = R2= $\frac{4.5}{2}$

= 2.25 in

The volume of second mug M2 is V2

the formula used will be

V=πr2h

V2 will be equal to

$V2= \pi r_{2} 2h_{2} \\V2 = \pi (2.25)(2)(4)\\V2 = 56.52$

V2 = 56.52

So as V2(56.52) is greater than V1(51.81) so mug 2 can hold the most
