Answer:
x = 3 ± 
or
x = 3 + , x = 3 -
Step-by-step explanation:
given f(x) = 2(x - 3)^2 - 8, find when f(x) = 40
So, we plug in 40 for f(x) in the 1st equation and solve for x. (Aim to got x on its own)
40 = 2 (x - 3)^2 - 8
+ 8 + 8
-----------------------------
48 = 2 (x - 3)^2
/2 /2
-----------------------------
24 = (x - 3)^2
square root both sides
--------------------
= x - 3
x = 3 ±
Answer:
r = 9/sin Ф or r = 9 csc Ф
Step-by-step explanation:
The polar form is represented as:
x = r cos Ф and
y = r sin Ф
We are given:
y = 9
Putting value in y = r sin Ф
9 = r sin Ф
=> r = 9/sin Ф
1/sin Ф = csc Ф
or, r = 9 csc Ф

Step-by-step explanation:
Answer:
<em>Here </em><em>it </em><em>is </em><em>a </em><em>parallelogram </em><em>so </em><em>opposite </em><em>angles </em><em>of </em><em>parallelogram </em><em>are </em><em>equal</em><em>. </em>
Step-by-step explanation:
<em>so</em>
<em>8x </em><em>+</em><em>1</em><em>7</em><em> </em><em>=</em><em> </em><em>12x </em><em>-</em><em> </em><em>3</em><em>9</em>
<em>1</em><em>7</em><em>+</em><em>3</em><em>9</em><em> </em><em>=</em><em> </em><em>12x </em><em> </em><em>-</em><em> </em><em>8</em><em> </em><em>x</em>
<em>4x </em><em> </em><em>=</em><em> </em><em>5</em><em>6</em>
<em>Therefore </em><em>x </em><em>=</em><em> </em><em>1</em><em>4</em>
Answer:
Compound interest = Rs 1,575 (Approx.)
Step-by-step explanation:
Given:
Amount invested = R.s 6,500
Rate of interest = 7.5% per annum
Number of year = 3 year
Find:
Amount of compound interest
Computation:
Compound interest = P[(1+r)ⁿ - 1]
Compound interest = 6500[(1+7.5%)³ - 1]
Compound interest = 6500[(1+0.075)³ - 1]
Compound interest = 6500[(1.075)³ - 1]
Compound interest = 6500[1.2423 - 1]
Compound interest = 6500[0.2423]
Compound interest = 1574.95
Compound interest = Rs 1,575 (Approx.)
