Answer:
[tex]x=6\\y=12[/tex]
Step-by-step explanation:
To find the value of x you can use sin rule
[tex]sin(60)=\frac{oppoaite}{hypotenuse}\\\frac{\sqrt{3} }{2} =\frac{x}{4\sqrt{3} } \\[/tex]
Use cross multiplication
[tex]4*\sqrt{3} *\sqrt{3} =2x\\4*3=2x\\12=2x\\\frac{12}{2} =\frac{2x}{2} \\6 =x[/tex]
To find the value of y you have to use sin rule again
[tex]sin(30)=\frac{opposite}{hypotenuse}\\\frac{1}{2} =\frac{x}{y} \\\frac{1}{2} =\frac{6}{y} \\[/tex]
Use cross multiplication
[tex]y=6*2\\y=12[/tex]
Hope this helps you.
Let me know if you have any other questions :-)
x = 5.9 units (just round it to 6)
y= 11.8 units (round it to 12)
Steps:
1) Use Soh Cah Toa to identify the unknown sides.
The side across the angle is the opposite. Therefore, the x side is opposite.
4√5 = 6.9 ( this side is the hypotenuse).
So we have the opposite side and the hypotenuse side. Therefore, we will use sine
2) Sin theta = opp/hyp
Sin 60 = opp/6.9
Multiply both sides by 6.9
6.9(sin60) = opp
5.9 = opp
3) now that you have side x, we will use x to figure out side y.
Identify the sides first. Side x is opposite and side y is the hypotenuse. Use sine to solve for side y
Sin theta = opp/hyp
Sin 30 = 5.9/hyp
0.5 = 5.9/hyp
Divide 0.5 and bring it over to the other side.
= 5.9/ hyp ÷ 0.5/1
= 5.9/hyp x 1/0.5
= 5.9/0.5
= 11.8 units (side Y)

HELP ME PLZZZ
Answers
Answer:
16 cmStep-by-step explanation:
Use ratios to solve:
125 m ⇒ 25 cm80 m ⇒ x cmFind the value of x:
x = 80*25/125 = 16The length of the building on the scale drawing for the given context is obtained as: 16 cm.
How are scale drawings formed?For a particular scale drawing, it is already specified that all the measurements' some constant scaled version will be taken. For example, let the scale be K feet to s inches.
Then it means
[tex]\rm 1\: ft : \dfrac{s}{k}\: in.[/tex]
All feet measurements will then be multiplied by s/k to get the drawing's corresponding lengths.
For the given case, The height of the building 125 meters was drawn as 25 cm in the scale drawing.
That means:
[tex]\rm 125 \: m : 25 \: cm\\\\1 \: m : \dfrac{25}{125} \: cm\\\\1 \: m :\dfrac{1}{5} \: \rm cm[/tex]
Since the length of the building in reality is 80 meters.
Thus, in scale drawing, it would become:
[tex]\rm 80 \: m = 80 \times 1 \: m : 80 \times \dfrac{1}{5} \: cm = 16 \: \rm cm[/tex]
Thus, The length of the building on the scale drawing for the given context is obtained as being of 16 cm.

How to find the factor of 6+x-x^(2)
PLS ANSWER TOT
Answers
(2 + x)(3 - x)
To factorise a quadratic we first need to think of factors of the number term (The 6).
Factors of 6 are 1 & 6 and 2 & 3.
What combination of addition or subtraction of these factor pairs will produce the second number (which is positive 1x)
3 minus 2 will give us 1, so we will use this pair
Throw up your brackets with the x's and the number pair we chose
(x 2) (x 3)
We chose 3 minus 2
So in our brackets we will put positive 3, negative 2

A scientist determines that the number of bacteria in a culture is modeled by the formula A(t)=4,000e0.02t, where t is the number of minutes after observation begins.
Answers
Using the exponential model given, the number of bacteria in the culture after 9 minutes after the observation began will be 4789
Given the exponential model :
[tex] A(t) = 4000e^{0.02t} [/tex] [tex] A(t) = Number\:bacteria\:in\:the\:culture\:after\:t\:minutes [/tex] t = number of minutes after observation beginsThe number of bacteria in the culture 9 minutes after the observation began can be calculated thus :
[tex]t = 9 \: minutes [/tex]
Substitute 9 for t in the exponential equation :
[tex] A(t) = 4000e^{0.02\times9} [/tex]
[tex] A(t) = 4000e^{0.18} [/tex]
[tex] A(t) = 4000 \times 1.1972173 [/tex]
[tex] A(t) = 4788.87 [/tex]
Therefore, the number of bacteria in the culture after 9 minutes will be about 4789
