Step-by-step explanation:
1.2
area of triangle = ½ × base × height
so,
height = 5cm
base = 4cm
now,
→ 1/2 × 4 × 5
→ 2 × 5 = 10 cm²
therefore, area of the ∆AED is 10cm².
1.3
area of rectangle = l × b
length = 8cm
breadth/width = 5cm
now,
area of BCDE
→ 8 × 5 = 40 cm²
now,
area of,
→ ABCD = BCDE - ∆AED
→ ABCD = 40 - 10 = 30
therefore, required area of ABCD is 30cm².

[tex]Evaluate: \int \frac{ \sin(2x) }{1 + \sin^{2} (x) }dx \\ [/tex]
Hopping for a great answer.
Answer:
ln (1 + sin^2(x)) + C
Step-by-step explanation:
Note that sin(2x) = 2 sin(x) cos(x).
So, the integrand is rewritten as:
(2 sin(x) cos(x)) / (1 + sin^2(x) ).
Now, make the substitution u = sin(x), so that du = cos(x) dx. Thus, in terms of the variable u, the integrand is
(2 u )/(1 + u^2).
Make another substitution v = 1 + u^2, so that dv = 2 u du, and the integrand in terms of v is
1 / v
Now, we integrate, and then back substitute to write that the indefinite integral is
ln |v| + C = ln |1 + u^2| + C = ln |1 + sin^2(x)| + C + ln (1 + sin^2(x)) +C, since 1 + sin^2(x) + 1 is positive for all real x.
Step-by-step explanation:
[tex]\large\underline{\sf{Solution-}}[/tex]
We have to evaluate the given integral.
[tex] \displaystyle \rm = \int \dfrac{ \sin(2x) }{1 + \sin^{2} (x) } \: dx[/tex]
[tex] \displaystyle \rm = \int \dfrac{2 \sin(x) \cos(x) }{1 + \sin^{2} (x) } \: dx[/tex]
Now let us assume that:
[tex] \rm \longmapsto u = 1 + { \sin}^{2}(x)[/tex]
[tex] \rm \longmapsto \dfrac{du}{dx} = 2 \sin(x) \cos(x) [/tex]
[tex] \rm \longmapsto dx = \dfrac{1}{2 \sin(x) \cos(x) } \: du[/tex]
Therefore, the integral becomes:
[tex] \displaystyle \rm = \int \dfrac{1}{u} \: du[/tex]
[tex] \displaystyle \rm = \ln(u) + C[/tex]
[tex] \displaystyle \rm = \ln(1 + sin^{2}x ) + C[/tex]
Therefore:
[tex] \displaystyle \rm \longmapsto \int \dfrac{ \sin(2x) }{1 + \sin^{2} (x) } \: dx = \ln(1 + sin^{2}x ) + C[/tex]
10. The half-life of a radioactive substance is 15
years.
Write an equation that can be used to determine
the amount, s(t), of 200 grams of this substance
that remains after t years. (2 points)
Determine algebraically, to the nearest year, how
long it will take for 1/10 of this substance to
remain. (3 points)
Answer:
s(t)=200(1/2)^t/13
Step-by-step explanation:
Here's answer:
https://www.nysedregents.org/algebratwo/619/algtwo62019-mrs.pdf
The number of years it will take for 1/10 of this substance to remain is; 50 years
What is the half life formula?The half life formula is;
N(t) = N₀(¹/₂)^(t/t_1/2)
where;
N(t) is quantity of the substance remaining
N₀ is initial amount of substance
t is time elapsed
t_1/2 is half life
Thus;
S(t) = 200(¹/₂)^(t/15)
We want to find the time it will take 1/10 of the substance to remain. Thus;
1/10 = (200/200)(¹/₂)^(t/15)
1/10 = (¹/₂)^(t/15)
t/15 = In(1/10)/In(¹/₂)
t/15 = 3.32193
t = 49.88 ≈ 50 years

Answer: Never(!) [assuming I understand/interpret the question properly]
Step-by-step explanation: The question wants to know how many months it will take for your neighbor's total cost be the same as yours, with three televisions. One has to interpret "total cost." I deem it to be the total accumulated costs, including installation. If you interpret it as the cost per month, then they charges are the same after the month the installation cast was paid. That's because the satellite provider charges per television, and 3*(13.32) is equal to the same 39.96/month charged by the cable provider. It the questions means total cumulative costs, the satellite customer will never exceed the cable customer's total bill, because of the installation fee ($75 for cable and free for satellite)

explain mathematically how you know 5y+4=10 and 5y=6 are equivalent
Answer:
see explanation
Step-by-step explanation:
Given
5y + 4 = 10 ( subtract 4 from both sides )
5y = 10 - 4 , that is
5y = 6
Thus 5y + 4 = 10 is equivalent to 5y = 6
Answer: y= 9x+6y=15

a line passes through the point (4, -4) and has a slope of -5 / 4
write an equation in slope-intercept form for this line
Answer:
y=-5/4x+1
Step-by-step explanation:
y- y-coordinate= slope(x- x-coordinate)
y- (-4)= -5/4 (x - 4)
y - (-4)= -5/4x +5
move (-4) to the other side of the equal sign, the sign changes to +4
y= -5/4x +5 +4
y=-5/4x+1

What is the slope of a line with one point at (2,1) and another at (5,3)
Answer:
Slope: 2/3
Step-by-step explanation:
Take the first point (2,1) as (x1, y1), and,
the second point (5,3) as (x2, y2).
Using the slope formula to calculate the slope:
m = [tex]\frac{y2-y1}{x2-x1}[/tex]
= (3-1)/(5-2)
= 2/3
Hence, the slope is 2/3

Answer:
B = 3.31662479
rounded to 3.32
Step-by-step explanation:
Pythagorean theorem: [tex]a^{2} + b^{2} = c^{2}[/tex]
A & B = the base and height
C = The diagonal line.
A & B can be base or height. ( base = 2 Height = 3. It can be [tex]2^{2} + 3^{2}[/tex] or [tex]3^{2} + 2^{2}[/tex] )
Because when you add it doesn't matter where each number is put.
I like doing b for the base, because there's a b in base, to make it easier for me. But you can do whatever.
A = 5
B = ?
C = 6
[tex]5^{2} + b^{2} + 6^{2}[/tex]
From here you will solve to get b.
[tex]5*5 + b^{2} = 6 * 6[/tex]
[tex]25 + b^{2} = 36[/tex]
25 - 25 + [tex]b^{2}[/tex] = 36 - 25
[tex]b^{2}[/tex] = 11
To under the exponent you have to [tex]\sqrt[/tex] it.
[tex]\sqrt{b_{2}}[/tex] = [tex]\sqrt{11}[/tex]
[tex]5^{2} + 3.32^{2} = 6^{2}[/tex]
B = 3.31662479

A. f(x) = -2x + 3
B. f(x) = x2 - 6x + 3
1. As x gets larger and larger in either
the positive or negative direction,
f(x) gets larger and larger in the
positive direction.
C. f(x) = 1 – x2 + 2x3
D.f(x) = 7 - x4

2. As x gets larger and larger in the
positive direction, f(x) gets larger
and larger in the positive direction.
As x gets larger and larger in the
negative direction, f(x) gets larger
and larger in the negative direction.
3. As x gets larger and larger in the
positive direction, f(x) gets larger
and larger in the negative (help please)direction.
As x gets larger and larger in the
negative direction, f(x) gets larger
and larger in the positive direction.
4. As x gets larger and larger in either
the positive or negative direction,
f(x) gets larger and larger in the
negative direction.
Using infinity limits, the matching pairs are:
A - 3.B - 1.C - 2.D - 4.The end behavior of a function f(x) is given by:
[tex]\lim_{x \rightarrow \infty} f(x)[/tex]
Function A:
[tex]f(x) = -2x + 3[/tex]
[tex]\lim_{x \rightarrow -\infty} f(x) = \lim_{x \rightarrow -\infty} -2x + 3 = \lim_{x \rightarrow -\infty} -2x = -2(-\infty) = \infty[/tex]
[tex]\lim_{x \rightarrow \infty} f(x) = \lim_{x \rightarrow \infty} -2x + 3 = \lim_{x \rightarrow \infty} -2x = -2(\infty) = -\infty[/tex]
Thus, matches with item 3.
Function B:
[tex]f(x) = x^2 - 6x + 3[/tex]
[tex]\lim_{x \rightarrow -\infty} f(x) = \lim_{x \rightarrow -\infty} x^2 - 6x + 3 = \lim_{x \rightarrow -\infty} x^2 = (-\infty)^2 = \infty[/tex]
[tex]\lim_{x \rightarrow \infty} f(x) = \lim_{x \rightarrow \infty} x^2 - 6x + 3 = \lim_{x \rightarrow \infty} x^2 = (\infty)^2 = \infty[/tex]
Thus, matches with item 1.
Function C:
[tex]f(x) = 1 - x^2 + 2x^3[/tex]
[tex]\lim_{x \rightarrow -\infty} f(x) = \lim_{x \rightarrow -\infty} 1 - x^2 + 2x^3 = \lim_{x \rightarrow -\infty} 2x^3 = 2(-\infty)^3 = -\infty[/tex]
[tex]\lim_{x \rightarrow \infty} f(x) = \lim_{x \rightarrow \infty} 1 - x^2 + 2x^3 = \lim_{x \rightarrow \infty} 2x^3 = 2(\infty)^3 = \infty[/tex]
Thus, matches with item 2.
Function D:
[tex]f(x) = 7 - x^4[/tex]
[tex]\lim_{x \rightarrow -\infty} f(x) = \lim_{x \rightarrow -\infty} 7 - x^4 = \lim_{x \rightarrow -\infty} -x^4 = -(-\infty)^4 = -\infty[/tex]
[tex]\lim_{x \rightarrow \infty} f(x) = \lim_{x \rightarrow \infty} 7 - x^4 = \lim_{x \rightarrow \infty} -x^4 = -(\infty)^4 = -\infty[/tex]
Thus, matches with item 4.
