3.9 point is equivalent to how many tenths?

Answers

Answer 1

Answer:

Answer with explanation:

3.9= 3 ones + 9 Tenths

1 ones =10 Tenths

3 ones =3 × 10 Tenths=30 Tenths

3.9=30 Tenths +9 Tenths

=39 Tenths

So, 39 Tenth

$=(39)/(10)\n\n=3.9$

Answer 2

Answer: 10 is in 3, so that's 30. There's another 9.

30 + 9 = 39.

39 tenths.

Jodi is retiring at the age of 65. When she retires, she estimates that she will need a monthly income for 25 years. If Jodi starts with $328,133.32 in an account that pays 6.2% interest compounded montly, approximately what monthly income will she be able to draw?

Answers

Given:
Principal = 328,133.32
Interest rate = 6.2%, compounded monthly
term = 25 years

A = P (1 + r/n)^nt
A = 328,133.32 (1 + 6.2%/12)^12*25
A = 328,133.32 (1 + 0.0052)^300
A = 328,133.32 (1.0052)^300
A = 328,133.32 (4.74)
A = 1,555,351.94 Total value after 25 years.

1,555,351.94 / 300 months = 5,184.51 per month.

Solve the system using multiplication for the linear combination method.6x – 3y = 3
–2x + 6y = 14
What is the solution to the system?
(2, 1)
(2, –3)
(2, –1)
(2, 3)

Answers

If you would like to solve the system of equations, you can calculate this using the following steps:

6x – 3y = 3
–2x + 6y = 14 /*3
_________
6x – 3y = 3
–6x + 18y = 42
_________
-3y + 18y = 3 + 42
15y = 45
y = 45/15
y = 3

6x – 3y = 3
6x - 3 * 3 = 3
6x = 3 + 9
6x = 12
x = 12/6
x = 2

(x, y) = (2, 3)

The correct result would be (2, 3).

(01.03) A box has dimensions of 17 inches long, 1.3 feet wide, and 8 inches high. What is the volume of the box? The formula for the volume is V = l ⋅ w ⋅ h. (1 point) 2121.6 cubic inches (in3) 176.8 cubic inches (in3) 14.7 cubic inches (in3) 1.2 cubic inches (in3)

Answers

we know that

the volume of a rectangular prism is equal to

$V=L*W*H$

where

L is the length of the box

W is the width of the box

H is is the height of the box

in this problem we have

$L=17\ in$

$W=1.3\ ft$

$H=8\ in$

Convert $1.3$ feet to inches

we know that

$1$ feet is equal to $12$ inches

$1.3*12=15.6\ inches$

$W=15.6 in$

Find the volume

$V=17*15.6*8$

$V=2,121.6\ in^(3)$

therefore

the answer is

$2,121.6\ in^(3)$

Convert 1.3 ft to inches which is 15.6in

then multiply all measurements using the volume formula which is L•W•H

17 * 15.6 * 8 = 2121.6 cubic inches

write an equation of the parabola that has the same shape as the graph of f (x)=4x^2, but with the point (-9,2) as the vertex

Answers

The equation of the parabola is y = a(x - h)^2 + k, where (h,k) is the coordinates of the vertex. In this case, the equation would be y = 4(x + 9)^2 + 2.

How will you define parabola?

Any point on a parabola is equally distant from the directrix, a fixed straight line, and the focus, a fixed point. An U-shaped plane curve is a parabola.

What is a parabola in a graph?

Drawing a parabola for the quadratic function f(x) = $ax^(2)$ + bx + c results in a U-shaped curve. When an is smaller than zero, the parabola's graph is downward (or opens downward). When the value of an is greater than 0, the parabola's graph ascends (or opens up).

Is a parabola a shape?

Every point on a parabola is equally distant from both a focus, or central point, and a directrix, or connecting line. It is a U-shaped curve that frequently appears in math.

Given,

Graph f(x) = $4x^(2)$

Vertex = (-9,2) = (h,k)

So, We can represent the equation in the form of

f(x) = y = a $(x-h)^(2)$ + k

= 4 $(x+9)^(2)$ + 2

Now simplifying the equation y = a $(x-h)^(2)$ + k to y = $ax^(2)$ + bx +c

f(x) = 4 $(x+9)^(2)$ + 2

= $4x^(2)$ + 72x + 326

∴ f(x) = $4x^(2)$ + 72x + 326 is the equation of parabola

#SPJ2

following f(x)=af(b(x-h))+k as my general guideline for writing transformations, you need to know the point (h,k) serves as the "new origin" of the function.
in your original equation (the squared function),
a=4
b=1
h=0
k=0
we need h=-9 and k=2, so plopping those numbers in gives you
f(x)=4(x+9)^2 +2
