Answer:

448

Step-by-step explanation:

So, here is the formula for that:

Fa=Ia(1+per)

First off, the <u>percentage</u>(per) would be represented as a <u>decimal</u>(.12). The <u>initial amount</u> (Ia) would be 400. The "+" is there because of <u>increasing interest.</u> This would be the equation:

400(1+.12)

Use the distributive property and you get 448

Answer:

Size 9

Step-by-step explanation:

The range is the highest value - the lowest value.

If the range is three, therefore the highest value - lowest value is 3

If 2 people in the family wear size 6, we can count that as 1 value. Since the question says that his shoe size can't be 3, so we let x be the number with the higher value.

x - 6 = 3

x = 9

Therefore Lee's shoe size is 9

Find x- and y-intercepts. Write ordered pairs representing the points where the line crosses the axes.
mario62 [17]

When you have a linear equation of the form y = mx, such as this one, you know immediately that the line passes thru the origin (0,0).  Were the form y = mx + b, then the y-intercept would be (0,b) and the x-intercept ( [-b/m, 0).

ASHA 777 [7]

The equation that models the movement of Tanus around Ini, where Ini is located at (0, 0) is x^2/75^2 + y^2/37.5^2 = 1

<h3>Write an equation that models the movement of Tanus around Ini, where Ini is located at (0, 0)</h3>

The given parameters are:

The length of Tanus’ major axis = 150 million miles

The length of its minor axis = 75 million miles

The center of the ellipse = (0, 0) --- the location of Ini

When the coordinate of the center of an ellipse is (0, 0), the standard form of the ellipse is represented as:

x^2/a^2 + y^2/b^2 = 1

Where:

Length of the major axis = 2a

Length of the minor axis = 2b

This means that:

2a = 150 and 2b = 75

Divide both sides of 2a = 150 by 2

a = 75

Divide both sides of 2b = 75 by 2

b = 37.5

Substitute b = 37.5 and a = 75 in the standard form of the ellipse represented as: x^2/a^2 + y^2/b^2 = 1

x^2/75^2 + y^2/37.5^2 = 1

Hence, the equation that models the movement of Tanus around Ini, where Ini is located at (0, 0) is x^2/75^2 + y^2/37.5^2 = 1

Find the numerical value of the log expression. \log a=7\hspace{15px} \log b=10\hspace{15px} \log c=3 loga=7logb=10logc=3 \log \
bija089 [108]

Answer:

  32

Step-by-step explanation:

  \log a=7\hspace{15px} \log b=10\hspace{15px} \log c=3\\\\ \log \dfrac{a^8c^2}{b^3}=8\log{a}+2\log{c}-3\log{b}=(8)(7)+(2)(3)-(3)(10)\\\\=56+6-30=\boxed{32}

__

The applicable rules of logarithms are ...

  log(ab/c) = log(a) +log(b) -log(c)

  log(a^b) = b·log(a)
