Answer:

The account interest rate is 0.80%

Step-by-step explanation:

A=P(1+r/100)^10

1462=1350(1+r/100)^10{divide both sides by 1350}

1462/1350=(1+r/100)^10{find the 10th root of both sides}

1.00800=1+r/100{multiply through by 100}

100.800=100+r

r=100.800-100

r=0.80%

Answer:

y = -2x + 7

Step-by-step explanation:

The point-slope form of the equation of a line is:

y - k = m ( x - h )

Where m is the slope and (h,k) is a point through which the line passes.

Suppose we know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:

[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]

We are given the point (3,1) and (7,-7), calculate the slope:

[tex]\displaystyle m=\frac{-7-1}{7-3}[/tex]

[tex]\displaystyle m=\frac{-8}{4}=-2[/tex]

m = -2

No w we use any of the given points: (3,1) and substitute in the equation of the line:

y - 1 = -2 ( x - 3 )

Multiplying:

y - 1 = -2x + 6

Adding 1:

y = -2x + 7

Answer:

81.25 ; 3091.48 ; 55.60

Step-by-step explanation:

Given the data :

45, 60, 25, 55, 75, 90, 100, 120, 105, 80, 0, 220

The mean :

ΣX/n ; n = sample size

ΣX = 45+60+25+55+75+90+100+120+105+80+0+220 = 975

n = 12

Mean = 975 / 12 = 81.25

The variance :

Σ(X - m)^2 / n - 1

Using calculator to save computation time :

The variance : (34006.24997 / 11)

Variance = 3091.48

The standard deviation :

Sqrt(Variance) = sqrt(3091.48) = 55.60

Answer: D) The graph of y = f(x) will shift down 13 units.​

Step-by-step explanation:

Let's define the transformations of translations.

If we start with a function f(x):

For A > 0.

An horizontal translation of A units to the right is written as g(x) = f(x - A)

An horizontal translation of A units to the right is written as g(x) = f(x + A).

A vertical translation of A units up is written as g(x) = f(x) + A

A vertical translation of A units down is written as g(x) = f(x) - A.

In this question we have the transformation:

y = f(x) - 13

This is a translation of 13 units down, then the correct option is:

D) The graph of y = f(x) will shift down 13 units.​

Step-by-step explanation:

10 to the power of 8 is 100,000,000 ( one hundred million )

100,000,000 x 3 = 300,000,000

On the other hand

10 to the power of 3 is 1,000

1,000 x 3 = 3,000

300,000,000 > 3,000

Approximate volume gas tank will hold is 17 gallons.

Step-by-step explanation:

The best way to approach a word problem like this

is to break it down into pieces, so we can understand it fully.

In this problem, we have a number, which we don't know.

We can use any variable to represent it.

So let's use the variable n to represent it.

"Two less than three times a number" means 3n - 2.

A common mistake is for students to put 2 - 3n.

However, the word "less than" switches the order around.

So we have 3n - 2 = 19.

Solving from here, we add 2 to both sides to get 3n = 21.

Now divide both sides of the equation by 3 and we have n = 7.

So the number is 7.

Step-by-step explanation:

first, find the value of angle t

angles of a triangle add up to 180.

with this, we can set up the equation

180 = t + 62 + 56

t = 62

to find angle w, find the sum of the top angles

25 + 56 = 81

again, sum of angles in a triangle adds to 180.

since we have the bottom right angle and the top angle, we can find the bottom left angle

180 = 56 + 62 + w

w = 37

finally we can find angle v

180 = 25 + w + v

180 = 25 + 37 + v

v = 118

another approach would be to find angle v after finding angle t.

because the two angles are supplementary, they add up to 180

angle v + angle w = 180

Answer: pretty sure it's the number you multiply by 4 is 17

Step-by-step explanation:

when you multiply 4 and 16 you'll get 64 then you subtract 19 and get 45 which is less than 47 so by reasoning if you were to multiply 4 and 17 you'll get 68 then you subtract 19 from 68 and you should get 49 ( you didn't include how much greater than 47 the number should be but the safest bet would be to use 17)

The value of x will be;

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The expression is,

⇒ 5x - 12 + 3x + 30 = 48

Now,

Solve the expression for x as;

The expression is,

⇒ 5x - 12 + 3x + 30 = 48

⇒ 8x - 12 + 30 = 48

⇒ 8x + 18 = 48

Subtract 18 both side as,

⇒ 8x - 18 = 48 - 18

⇒ 8x = 30

Divide by 8 as;

⇒ x = 30/8

⇒ x = 3.75

Thus, The value of x will be;

⇒ x = 3.75
