Answer: 6 years

Step-by-step explanation:

Formula to calculate compound amount: [tex]A=P(1+r)^t[/tex], where P= Principal , r=rate of interest, t= time

Given: P = £400, r = 3% = 0.03 , A= 475

Required equation: [tex]400(1+0.03)^t\geq475[/tex]

[tex]400(1.03)^t\geq475\\\\\Rightarrow\ (1.03)^t\geq\dfrac{475}{400}\\\\\Rightarrow\ (1.03)^t\geq1.1875[/tex]

Taking log on both sides , we get

[tex]t \log 1.03\geq\log1.1875\\\\\Rightarrow\ t(0.0128372)\geq(0.0746336)\\\\\Rightarrow\ t\geq\dfrac{0.0746336}{0.0128372}=5.81385\approx6[/tex]

Hence, he needs to invest the money for 6 years to get atleast £475.

Answer:

because 3 spheres is inside the cylinder and they are placed close together

=> The height of the cylinder is 3 times the diameter

=> the height is 18cm

the volume of the cylinder is 3,14.18.(6/2)² = 508,68

because 3 spheres have the same diameter

=> the volume of 3 spheres is 4.3,14.3³ = 339,12

=> the volume of the cylinder that is left empty is 508,68 - 339,12 = 169,56

Step-by-step explanation:

Answer:

The answer is 508,68

Step-by-step explanation:

Since the volume of the cylinder is equal to the area of the permanent base multiplied in the height

Since the radius of the base is equal to 3 and since the area of its cylinder is equal to

[tex]314 \times 3 \times 3 = 28.26[/tex]

When the height equal to 18

Then the volume equal to

[tex]28.26 \times 18 = 508.68[/tex]

Answer:

31.4 in

Step-by-step explanation:

the formula for circumference is 2*[tex]\pi[/tex]*radius. Since the diameter (which is the radius multiplied by 2) is labeled we can divide 10 by 2 to get the radius. 10/2 is 5. Since pi is an infinite number, we round it to 3.14. Then, plug in the numbers. The expression will be 2*3.14*5. 2* = 10 and 10 * 3.14 you can just move the decimal so the answer is 31.4.

Answer: y=-9x+5

Step-by-step explanation:

slope intercept form is y=mx+b

simply plug in the values.

m= the slope

the slope you gave was -9, so plug that in to m.

b= the y intercept aka when the number touches the y axis. in this case, it would be 5.

y=-9x+5

Answer:

Step-by-step explanation:

15.50+what she had in the bank already = what she has now

Step-by-step explanation:

Elise's new credit card balance is $-50.

Elise's credit card balance is negative. This means that she has withdrawn more money than she has deposited. Elsie thus owes the bank $-120. If she paid $70, the amount she owes would be reduced by $70.

Elise's new credit card balance = credit card balance + payment made

$-120 + $70 = $-50

Step-by-step explanation:

f(4) is just asking what the y value is when x=4 which is 1

f(-3) = -4

This has no minimum or maximum because the range is all real numbers (the y value goes to infintiy and negative infinity)

f(3)=6

f(0)= 3

This has a minimum because the lowest y value possible is not infinity (it's 2)

f(1)= -5

f(4)= -2

max= -1

f(-1)= 0

f(6)= -5

The inequality representing the problem will be x+3 ≥ 8

A relationship between two expressions or values that are not equal to each other is called inequality.

Given that, Brad has $75 in his savings account and adds $25 every month he doesn't make any withdrawals from the account, and saves at least $200.

Let the number of months be x,

75 + 25x ≥ 200

25(3+x) ≥ 200

x+3 ≥ 8

Hence, The inequality is x+3 ≥ 8
