Write the equation 3x+2y- 5 = 0 in normal form. Then, find the length of the normal and the angle it makes with the

1 answer:

8 0

Hey, hope you are having a nice day. The answer I got was y=-1.5x+2.5. This was because most equations are y=mx+b. So y had to be by itself.
3x+2y-5=0
-2y. -2y
3x-5=-2y since 0 doesn’t do anything
——- ——
-2. -2
-1.5 +2.5 =y

The value of Adam's model railway is $550.

garik1379 [7]

Answer:(c)

Step-by-step explanation:

Given

The initial value of Adam's model is $A_o=\$550$

the value increases exponentially with the rate of $r\%$

Time period $t=5\ years$

Final amount $A=\$736$

Exponential growth is given by

$\Rightarrow A=A_o(1+r)^t$

Putting values

$\Rightarrow 736=550(1+r)^5\\\\\Rightarrow (1+r)^5=1.338$

$\Rightarrow 1+r=1.05999\\\Rightarrow r=0.05999\ or\ 5.99\%\approx 6\%$

Option (c) is correct

Write an equation in slope-intercept form of the line that passes through (-1, 4) and (0, 2)

MrMuchimi

Answer:

y = -2x + 2

General Formulas and Concepts

Pre-Alg

Order of Operations: BPEMDAS

Algebra I

Slope-Intercept Form: y = mx + b

m - slope

b - y-intercept

Slope Formula: $m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

Step 1: Define

Point (-1, 4)

y-intercept (0, 2)

Step 2: Find slope m

Substitute: $m=\frac{2-4}{0+1}$
Subtract/Add: $m=\frac{-2}{1}$
Divide: $m=-2$

Step 3: Write linear equation

y = -2x + 2

Answer:

h/3 + p/3 + 8 = k

Step-by-step explanation:

h+p=3(k-8)

h+p=3k-24

h+p+24=3k

h/3 + p/3 + 8 = k

If the sixth term in a geometric sequence is 1/625, and the common ratio is 15, find the explicit formula of the sequence.

Nonamiya [84]

Answer:

The explicit formula of the sequence is $a_n=5(\frac{1}{5})^{n-1}$ for $n \geq 2$

Step-by-step explanation:

Sixth term in a geometric sequence = $\frac{1}{625}$

Common ratio = $\frac{1}{5}$

Formula of nth term = $a_n=ar^{n-1}$

Substitute the values

So, $\frac{1}{625}=a(\frac{1}{5})^{6-1}\\\frac{1}{625}=a(\frac{1}{5})^{5}\\\frac{1}{625} \times 5^5=a$

5=a

Substitute the value in 1

So, $a_n=5(\frac{1}{5})^{n-1}$

So, Option C is true

Hence the explicit formula of the sequence is $a_n=5(\frac{1}{5})^{n-1}$ for $n \geq 2$
