Answer:
1) x= 35 , y = 18
2) x = 20 , y = 23.33
3) x = 11
4) x = 9
5) x = 10
Step-by-step explanation:
1)As the triangles are similar, here the ratio is as;


from here, x=35 and y = 18
2)As the triangles are similar, here the ratio is;


from here, x=20 and y= 23.33
3)As the triangles are similar, here the ratio is;

![\frac{24}{x +5} = \frac{54}{36} here, x = 114)As the triangles are similar, here the ratio is; [tex]\frac{AB}{AD} = \frac{BC}{DE}](https://tex.z-dn.net/?f=%5Cfrac%7B24%7D%7Bx%20%2B5%7D%20%3D%20%5Cfrac%7B54%7D%7B36%7D%20%3C%2Fp%3E%3Cp%3Ehere%2C%20x%20%3D%2011%3C%2Fp%3E%3Cp%3E4%29As%20the%20triangles%20are%20similar%2C%20here%20the%20ratio%20is%3B%3C%2Fp%3E%3Cp%3E%20%20%20%20%3Cstrong%3E%5Btex%5D%5Cfrac%7BAB%7D%7BAD%7D%20%3D%20%5Cfrac%7BBC%7D%7BDE%7D)

here, x = 9
5)As the triangles are similar, here the ratio is;

,
from here, x = 10
Answer:
(-1,5) (3, 1/125)
Step-by-step explanation:
I used desmos to graph the equation then the points attached you will see the screenshot so you can be sure. The points are the same color as the circle on the left side of the point. Hope this helps!
Domain 0≤x≤12 this means the domain (x values) are between x=0 and x=12 and you started measuring the degree of temperature starting at a time of 0 and stopped measuring the temperature at a time of 12 hours
Range -4≤y≤4 this means the range (y values) are between y=-4 and y=4. The range is referring to the degree in celcius based on what time you measured it
Hope this helps!
Answer:
1. B 2. C
Step-by-step explanation:
1. x^2-18x+(18/2)^2=19+(18/2)^2
(x-18/2)^2=100
(x-9)^2=100
x1= -1 x2= 19
2. x^2=81
x=+-9
x1=-9 x2=9
