Answer:

Use the given functions to set up and simplify x^2+1/x^2.
x+1/x=6=x=1/6
x^2+1/x^2=1/x^2

Answer:

3/10

Step-by-step explanation:

total boxes = 100

shaded boxes = 30

fraction =30/100

= 3/10

Rs.13680 is the answer.

Step-by-step explanation:-

Given-

• Principal (P) = Rs.57,000

• Rate (r%) = 6%

[tex]→ \frac{6}{100} [/tex]

[tex]→ 0.06[/tex]

• Time (n) = 4 years

Applying Interest formula,

[tex]→In=P \times R \times T[/tex]

[tex]→57,000 \times 0.06 \times 4[/tex]

[tex]→Rs.13680[/tex]

Hence, the interest is Rs.13680

Answer:

x = ln (y)

Step-by-step explanation:

There's two main ways to solve this. When there is no logarithm in the equation you can either take the log of both sides OR change an exponential equation to logarithmic form.

See image.

note: log_2 (2) = 1

log_3 (3) = 1

log_4 (4) = 1

log_5 (5) = 1

if the base and the article are the same then it equals 1

ln e = 1

because ln e means the same thing as log_e

log_e (e) = 1

e is just a number!

If you are changing exponential form to logarithmic form, the base is the same in both forms. The base is the base. The base in exponential form is the base in logarithmic form. The base is the base. The exponent and article basically switch places to change forms.

Answer:

[tex](a-b)(a+c)[/tex]

Step-by-step explanation:

Factor each half of the expression separately:

[tex]a^2-ba+ac-cb\\a(a-b)+c(a-b)[/tex]

Since both a and c are being multiplied by a-b, we can combine them to get:

[tex](a-b)(a+c)[/tex]

Answer:

B

Step-by-step explanation:

f(x) = x³

g(x) = (x - 3)³ - 2

The inside of the parenthesis represents a horizontal shift

If the number operation being done to x inside of the parenthesis is adding ( or if the number is positive ) then the graph will shift to the left. If the operation being done inside of the parenthesis to x is subtraction ( or if the number is negative ) then the graph will shift to the right.

The operation being done is subtraction therefore it will shift to the right. So it will go 3 units to the right.

the number on the outside works like a y intercept. if it's positive it goes up, if it's negative it goes down. the number is -2 so it will go down 2 units

we can conclude that g is shifted 3 units right and 2 units down

the answer is B

Answer:

85%

Step-by-step explanation:

P(a) = 25%=1/4

P(b) = 60%=3/5

P(a and b) = 1/4 + 3/5 = 5+12/20 = 17/20 = 85%

Answer:

The probability of A and B is 85%

Step-by-step explanation:

It is 85% because 25% is 0.25 or 25/100(1/4), and 60% is 0.6 or 6/10(3/5). 0.6+0.25=0.85 and to convert it back to a percentage you need to times 100%. 0.85x100%=0.85x100 with a percentage symbol =85%.

Answer:

x=14.87

Step-by-step explanation:

What we want to use is pythagoras theorem:

a^2+b^2=c^2, where c is the hypotenuse

10^2+11^2=x^2

221=x^2

x=[tex]\sqrt{221}[/tex]

x=14.866...

x=14.87

Answer:

a)  y = 7    

b) y =5 sin t

Step-by-step explanation:

35*75 is

2625

2625/400 is

6.5625

Since you cannot have a decimal amount of a bag, you should purchase

(rounding)

7 bags of fertilizer

Answer:

7 bags

Step-by-step explanation:

First thing you need to do is figure out the area of the garden. Area=length×width, so just put in your numbers, 35×75=2625 square feet. One bag covers 400 feet, so you divide the area by 400, 2625÷400=6.5625. You can't buys 6.5625 bags of fertilizer, so you have to go up to the next whole number which is 7.

Answer:

They flipped the wrong fraction it should have been 2/3 as the fraction you divide by is the fraction you flip

Answer:

19.7 inches

Step-by-step explanation:

circumference of a circle = 2πr

62 = 2*22/7 *r

r = 62 * 7 / 44 = 9.86

diameter = 2* r

= 2* 9.86

= 19.7 inches

Answer: I do not understand

Step-by-step explanation:

Answer: 116.4 and 63.6 degrees

Step-by-step explanation:

Let the angle be x, so supplement is 180-x.

This means x - 52.8 = 180 - x

2x = 232.8

x = 116.4

So the angle measures are 116.4 and 63.6 degrees

Answer:

The calculator costs $91.80 in total.

Step-by-step explanation:

85*8% = 6.80

85+6.80 = 91.80

Step-by-step explanation:

[tex]x \: as \: the \: first \: piece \\ 2x \: as \: the \: second \: piece \\ 4(2x) = 8x \: as \: the \: third \: piece[/tex]

[tex]x + 2x + 8x = 440 \\ 11x = 440 \\ x = \frac{440}{11} \\ x = 40 \\ 2x = 2 \times 40 = 80 \\ 8x = 8 \times 40 = 320 [/tex]
