the diagram of g||h, with transversal f,
a rectangle is 12 feet long and 5 feet wide. if the length of the rectangle is increased by 25% and the width is decreased by 20% what is the change in the area of the rectangle
Answer:
60% decrease in area
Step-by-step explanation:
12 x5 == 60 sq feet (original area)
9 x 4 == 36 sq feet (new area)
36/60 = 6/10 = 60%

Solve the following trigonometric equation over the interval of [0,2π). Show your work, thank you!
[tex] \large{2sin \theta tan \theta = - 3}[/tex]
Answer:
[tex] \rm \displaystyle \theta = \{ {150}^{ \circ} , {240}^{ \circ} \}[/tex]
Step-by-step explanation:
we would like to solve the following equation:
[tex] \displaystyle 2 \sin( \theta) \tan( \theta) = - 3[/tex]
to do so we need to put the equation in term of a function of a angle therefore rewrite tanθ:
[tex] \displaystyle 2 \sin( \theta) \cdot \frac{ \sin( \theta) }{ \cos( \theta) } = - 3[/tex]
simplify multiplication:
[tex] \displaystyle \frac{ 2\sin^{2} ( \theta) }{ \cos( \theta) } = - 3[/tex]
cross multiplication:
[tex] \displaystyle 2\sin^{2} ( \theta) = - 3 \cos( \theta) [/tex]
isolate -3cosθ to left hand side and change its sign:
[tex] \displaystyle 2\sin^{2} ( \theta) + 3 \cos( \theta) = 0[/tex]
well we can rewrite sin²θ by applying Pythagorean theorem and that yields:
[tex] \rm \displaystyle 2(1 - \cos^{2} ( \theta)) + 3 \cos( \theta) = 0[/tex]
distribute:
[tex] \rm \displaystyle 2 - 2\cos^{2} ( \theta) + 3 \cos( \theta) = 0[/tex]
now notice that our equation ended up with a pattern and that is Quadratic thus by letting cosθ be x to transform the equation:
[tex] \rm \displaystyle 2 - 2 {x}^{2} + 3 x = 0[/tex]
rearrange it to standard form:
[tex] \rm \displaystyle - 2 {x}^{2} + 3 x + 2 = 0[/tex]
divide both sides by -1:
[tex] \rm \displaystyle 2 {x}^{2} - 3 x - 2 = 0[/tex]
well we can factor the quadratic to do so rewrite -3x as -4x+x:
[tex] \rm \displaystyle 2 {x}^{2} - 4 x + x - 2 = 0[/tex]
factor out 2x:
[tex] \rm \displaystyle 2x ({x}^{} - 2)+ x - 2 = 0[/tex]
factor out 1:
[tex] \rm \displaystyle 2x ({x}^{} - 2)+ 1(x - 2 ) = 0[/tex]
group:
[tex] \rm \displaystyle (2x + 1)(x - 2 ) = 0[/tex]
by Zero Product property we obtain:
[tex] \rm \displaystyle \begin{cases} 2x + 1 = 0\\ x - 2 = 0 \end{cases}[/tex]
cancel 1 from the first equation and add 2 to the e equation:
[tex] \rm \displaystyle \begin{cases} 2x = - 1\\ x = 2\end{cases}[/tex]
substitute back:
[tex] \rm \displaystyle \begin{cases} 2 \cos( \theta) = - 1\\ \cos( \theta) = 2\end{cases}[/tex]
since cosθ is only defined for the interval [1,-1] the second equation is false for any value of θ but we can still continue the first equation
[tex] \rm \displaystyle \begin{cases} 2 \cos( \theta) = - 1\\ \cos( \theta) \neq 2\end{cases}[/tex]
divide both sides by 2:
[tex] \rm \displaystyle \cos( \theta) = \frac{ - 1} {2}[/tex]
by unit circle we acquire:
[tex] \begin{cases} \rm \displaystyle \theta = {150}^{ \circ} \\ \theta = {240}^{ \circ} \end{cases}[/tex]
add period of 2nπ:
[tex] \begin{cases} \rm \displaystyle \theta = {150}^{ \circ} + 2n\pi\\ \theta = {240}^{ \circ} + 2n\pi \end{cases}[/tex]
for the interval [0,2π) θ is only defined when n is 0 Thus:
[tex] \begin{cases} \rm \displaystyle \theta = {150}^{ \circ} + 2(0)\pi\\ \theta = {240}^{ \circ} + 2(0)\pi \end{cases}[/tex]
simplify:
[tex] \begin{cases} \rm \displaystyle \theta = {150}^{ \circ} \\ \theta = {240}^{ \circ} \end{cases}[/tex]
hence,
θ is equal to 150° and 240°
Can y’all help me plz
Answer:
Step-by-step explanation:
I think it is A
Answer:
A. 54 pie cm³
Step-by-step explanation:
height of the cylinder = 6 × radius of one sphere.
= 6 × 3
= 18 cm
as we can see 3 spheres make up the height of one cylinder,
height of one sphere = 6 cm (3 + 3)
with three spheres it becomes = 6 × 3
= 18 cm
volume of a cylinder = [tex]\pi[/tex] r² h= [tex]\pi[/tex] × (9)² × 18
= 27 × 6 [tex]\pi[/tex]
volume of a sphere = 4/ 3 × [tex]\pi[/tex] 3³= 36 [tex]\pi[/tex]
for 3 spheresvolume = 3 × (36 [tex]\pi[/tex] )
= 27 × 4 [tex]\pi[/tex]
volume of the empty space
= volume of cylinder- volume of 3 spheres
= 27 × 6 [tex]\pi[/tex] - 27 × 4 [tex]\pi[/tex]
= 27 [tex]\pi[/tex] ( 6 - 4)
= 27 × 2 [tex]\pi[/tex]
= 54 [tex]\pi[/tex] cm³What is the approximate volume of the cylinder? Use 3.14 for π.
top of the cylinder is 9 bottom is 4
A. 324 cm3
B. 452.16 cm3
C. 734.76 cm3
D. 1,017.36 cm3
c. 734.76 cm3 espero que te sirva :)
What is the value of the discriminant for the quadratic equation –3 = –x2 + 2x? Discriminant = b2 – 4ac –8
Answer:
32
Step-by-step explanati
everyone knows that
Answer:
[tex]16[/tex]
Step-by-step explanation:
The discriminant of a quadratic in standard form [tex]ax^2+bx+c[/tex] is given by [tex]b^2-4ac[/tex].
The quadratic [tex]-3=-x^2+2x[/tex] in standard form is [tex]-x^2+2x+3[/tex]. Thus, we can assign the following values:
[tex]a[/tex] of -1[tex]b[/tex] of 2[tex]c[/tex] of 3Therefore, the discriminant of this quadratic is [tex]2^2-4(-1)(3)=4+12=\boxed{16}[/tex]

Answer:
d. Keisha did not make a mistake
Step-by-step explanation:
3+(-4)-7
3+(-4)+(-7) adding negatives is the same as subtracting
3+(-11) -4 and -7 do make -11
-8 3 and -11 do make -8

Answer:
9 pi
Step-by-step explanation:
First find the circumference of the circle
C =2 * pi *r
C = 2 * pi *9
C = 18 pi
This is a semicircle which is 1/2 of a circle
Take 1/2 of the circumference
1/2 C = 1/2 ( 18 pi)
1/2 C = 9 pi
can you construct a polygon with angles measures of 60, 60, and 62 degrees? explain your reasoning. ILL GIVE BRAINLIEST
Answer:
No
Step-by-step explanation:
Given 3 angles, the shape is a triangle.
The sum of all angles in a triangle = 180°
60° + 62° + 60° = 182°
Since it doesn't equal to 180°, it can't form a polygon
