Answer:
6.5Step-by-step explanation:
The triangle shown is right angles where;
opposite side = x
adjacent side = 8
Angle of elevation = 39°
Using TOA trigonometry identity
tan 39° = opp/hyp
tan 39° = x/8
x = 8tan39°
x = 6.48
Hence the value of x is 6.5 to the nearest tenth

Which equation represents a linear function that is proportional?
Answers
Answer:
A) f(x) = 1/3x
Step-by-step explanation:
You can rule out B and C-
B is a quadratic function, seeing as how x is being squared, and C is an absolute value function. Neither of these are linear so you don't have to worry about it here.
That leaves us with A and D, which are both linear.
Linear functions usually take the form of f(x) = mx + b. In a proportional linear function, b = 0.
So with that in mind, you should see that the b value for f(x) = 2x + 11 is 11, which should rule D out as well.
That leaves you with f(x) = 1/3x. As you can see, there's no b value in this function, which means b = 0 and the function is proportional.
Hope this helped :D
Una recta atraviesa el punto (4,-6) Y tiene una pendiente igual a 5/4
Ayúdenme con este problemaaa porfavor
Answers
Answer:
y=5/4x-11
Step-by-step explanation:
tenemos un punto (4,-6) y una pendiente equal a 5/4.
usa la ecuación y=mx+b (m es la pendiente, b es el y interceptar)
porque sabemos la pendiente es 5/4, ahora mismo la ecuación es:
y=5/4x+b
en el punto, x=4, y=-6
podemos sustituir los números en la fómula para resolver b
-6=4(5/4)+b
-6=5+b
-11=b
entonces,
la ecuación de la recta es y=5/4x-11

The radius of a circle is 9 times the radius of a smaller circle. The area of the smaller circle is 50 square centimeters. What is the area of the larger circle?
Answers
Answer:
Let R = radius of big circle
r=radius of small circle
A1=Area of small circle
A2=Area of big circle
R=9r
A1=50cm^2
A1=pi*r*2
A2=pi*R^2
A2=pi*(9r)^2
A2=81*pi*r^2
A2=81*A1
A2=4050cm^2
Hence the big circle has area of 4050cm^2
Step-by-step explanation:
The answer is 4050 cm²
What is the area and circumference of a circle?The circumference (or) perimeter of a circle = 2πr units. The area of a circle = πr2 square units. Where r is the radius of the circle. The circumference of the circle or the perimeter of the circle is the measurement of the boundary of the circle. Whereas the area of the circle defines the region occupied by the circle.
Given here: The radius of a circle is 9 times the radius of a smaller circle. And area of the smaller circle is 50 cm² then let the area of the larger circle be x
π9²/π1² =x/50
x=4050
Hence, The answer is 4050 cm²
