Answer:

307.5$

Step-by-step explanation:

150$. 105% of it added.

Since 105% is 1.05, multiply the percentage by the cost to get the money added.

150*1.05=157.5

Then ADD it to the price/savings.

150+157.5=307.5$

Therefore, The bond be worth when Elena is 20 years old,

⇒A= $307.5

Therefore, after 20 years the the bond worth $307.5

Answer:

-\dfrac{b^2}{16a^4}

Step-by-step explanation:

Given expression:

\dfrac{(2a)^{-2}b^5}{-4a^2b^3}

\textsf{Apply the exponent rule}\quad (ab)^c=a^c \cdot b^c:

\implies \dfrac{2^{-2}a^{-2}b^5}{-4a^2b^3}

Separate the variables:

\implies \dfrac{2^{-2}}{-4}\cdot \dfrac{a^{-2}}{a^2}\cdot \dfrac{b^5}{b^3}

\textsf{Apply the exponent rule} \quad \dfrac{a^b}{a^c}=a^{b-c}:

\implies \dfrac{2^{-2}}{-4}\cdot a^{-2-2}\cdot b^{5-3}

\implies \dfrac{2^{-2}}{-4}\cdot a^{-4}\cdot b^{2}

\textsf{Apply the exponent rule}\quad a^{-n}=\dfrac{1}{a^n}:

\implies \dfrac{1}{-4(2^2)}\cdot \dfrac{1}{a^4}\cdot b^{2}

\implies -\dfrac{1}{16}\cdot \dfrac{1}{a^4}\cdot b^{2}

Simplify:

\implies -\dfrac{b^2}{16a^4}

The equation of a circle with radius r and center at point (a, b) is given by
(x - a)^2 + (y - b)^2 = r^2
1.) For the circle given by x^2 + y^2 = 24
(x - 0)^2 + (y - 0)^2 = (√24)^2
Therefore, center = (0, 0) and radius = √24 = 4.9 units

3.) x^2 + y^2 -10x -2y = -10
x^2 - 10x + (-5)^2 + y^2 - 2y + (-1)^2 = -10 + (-5)^2 + (-1)^2
x^2 - 10x + 25 + y^2 - 2y + 1 = -10 + 25 + 1
(x - 5)^2 + (y - 1)^2 = 16
(x - 5)^2 + (y - 1)^2 = 4^2

What is the equation of the line through 4.2 and 0, -2?
MissTica

Answer:

y = x-2

Step-by-step explanation:

y = mx + b as an equation

m = slope

slope = (change in y) / (change in x) = (y₂-y₁)/(x₂-x₁) = (y₁-y₂)/(x₁-x₂) = (2-(-2))/(4-0) = 4/4 = 1

y = 1*x + b

plug a value in, e.g. (0, -2)

-2 = 1 * 0 + b

-2 = b

our equation is thus

y = x - 2
