Answer 1

Answer:

a. 8m

b. 7cm

Step-by-step explanation:

a. Area of a square is s², where s is the side length.

To find s:

s² = 64

s = √64

s = ±8

length cannot be negative, hence it is positive 8

b. Perimeter of a square is 4s = P, where P is the perimeter and s is the side length.

4s = 28

s = 7

B is the correct answers

Step-by-step explanation:

Issun Sengeki... Messatsu!

In my opinion, I'd say A and C aren't functions, but B is a function.

The reason being is because every "X" value has a "Y" value. For those that don't have exactly 1 "Y" value aren't functions.

A. has more "Y" values than "X" values, so that proves not to be a function.B. Has "X" values that are exactly appointed to a "Y" value.C. Has one "X" value that's missing, and a "Y" value that doesn't exist.

Hope this helps!

Answer:

tan x

Step-by-step explanation:

(tan-x)[sec(pi/2)-x] (sin-x)

We know that tan (-x) = - tan (x) and sin (-x) = - sin (x)

-(tanx)[sec(pi/2)-x] -(sinx)

(tanx)[sec(pi/2)-x] (sinx)

Using the identity sec = 1/ cos

sec ( pi/2 -x) =1/cos ( pi /2 -x)

We know that cos (s-t)=cos (s) cos(t) + sin (s) sin (t)

1/ ( cos pi/2 cos x + sin pi/2 sin x) = 1/(0 cos x - 1 sinx) = 1 / sinx

Replacing into the equation

(tanx)[1/ sinx] (sinx)

Answer:

d) x = 4/3

Step-by-step explanation:

Given equation,

→ -x + (3/7) = 2x - (25/7)

Now the value of x will be,

→ -x + (3/7) = 2x - (25/7)

→ -x - 2x = -(25/7) - (3/7)

→ -3x = -28/7

→ -3x = -4

→ x = -4/-3

→ [ x = 4/3 ]

Hence, the value of x is 4/3.

A researcher needs 25 mL or 45%
base Solution for a certain
expiriment, but she has only 15%
Solution and 65% Solution. How
many mL of the 15% and the
65% Solutions should she mix to
get what She needs?

Answers

Answer:

10 mL of 15% solution

15 mL of 65% solution

Step-by-step explanation:

If x is the volume of 15% solution, and y is the volume of 65% solution, then:

x + y = 25

0.15 x + 0.65 y = 0.45 (25)

Solve with substitution:

0.15 x + 0.65 (25 − x) = 0.45 (25)

0.15 x + 16.25 − 0.65 x = 11.25

0.50 x = 5

x = 10

y = 15

Answers

Answer:

The answer is $4025

Step-by-step explanation:

In this problem we are given his annual salary. meaning per year. to find how much he makes in a month, we must divide by how many months there are in a year.

there are 12 months in a year.

so, 48300/12= 4025

hope this helps!

Answer:

$4,025 is his monthly salary.

Step-by-step explanation:

Annual salary means yearly. Since there are 12 months in a year, you would just take his annual (yearly) salary and divide it by 12 in order to get his monthly salary. Thus it would be:

[tex]\frac{48300}{12} =4025[/tex]

What number should be added to both sides of the equation to complete the square?b. Solve for x by completing the square. Class description: A MyString class should behave much like the c++ string class. The class should use a dynamically allocated char array to hold a character string. If the amount of memory allocated to the array is too small to complete some necessary task (e.g., assigning a new character string to the object) the object should automatically double its capacity until it is large enough to complete the task. If it's discovered that the object is using less than 25% of its capacity the object should shrink to half its capacity until it is using more that 25% of its capacity.Assignment: Implement the MyString class using a header and implementation file named MyString.h and MyString.cpp respectively. Even though MyString.h will be provided on the upload site, create own version for testing code locally. Make sure to properly test code on by creating a test driver that fully tests every function created in the MyString classMemory Requirements: MyString should start with 10 bytes of allocated memory and should grow in size by doubling. So, we should be able to predict the capacity of MyString as acquiring a patten of 10, 20, 40, 80, bytes of memory depending of the number of characters stored.Attributes:int size the number of characters currently stored in the string object. Do NOT count the NULL character.int capacity the number of bytes currently allocated. This should always be at least size + 1.
