A rectangle has a length of 28 feet less than 6 times its width. If the area of the rectangle is 48 square feet, find the length of the rectangle.
brainliest and thanks <3
help asap
Answer:
length = 8
Step-by-step explanation:
l x w = 48
let l = 6w - 48
x(6w - 28) = 48
6w² - 28w - 48 = 0
(6w + 8) (w - 6) = 0
w = 6
l = 6(6) - 28 = 36 - 28 = 8
For her birthday, Bonnie's parents gave her $5,425.00 which they put into a savings account that earns 15% interest compounded annually. When Bonnie started college, she withdrew the entire balance of $16,642.00 and used it to pay for tuition. How long was the money in the account?
Answer:
15% of $5425.00 = 5425 x- 15% = 813.75
$16,642.00 ÷ 813.75 = 20.3 = 20
So approx. 20 years

Answer:
The function is constant from x = -2 to x = 1.
Step-by-step explanation:
To find the range of where the function is constant, just look at the graph where the line is horizontal. It is horizontal from the x-values of x=-2 to x=1, and this is the range of when the function is constant.

In triangle XYZ, let angle Y be a right angle, mZ = 54°, and YZ = 361. Find the area of the
triangle. Round to the nearest whole number.
Answer:
89,709
Step-by-step explanation:
∡Z= 54°
tan 54 = XY / 361
XY = 361 · tan 54°
XY = 497
A = 1/2 (361) (497)
the difference between area and surface area.
Answer:
Area- Measurment of the size in the flat surface of a plane (Two Dimensional)
Surface Area- Measurment of the exposed surface of a soilid shape (Three Dimensional)

How to find the derivative of the below question?
Given:
[tex]y=\dfrac{x}{\sqrt{x-1}}[/tex]
To find:
The derivative of the given problem.
Solution:
Chain rule : [tex]\dfrac{d}{dx}f(g(x))=f'(g(x))\cdot g'(x)[/tex]
Quotient rule : [tex]\dfrac{d}{dx}\left(\dfrac{f(x)}{g(x)}\right)=\dfrac{g(x)f'(x)-f(x)g'(x)}{[g(x)]^2}[/tex]
We have,
[tex]y=\dfrac{x}{\sqrt{x-1}}[/tex]
Differentiating with respect to x using chain rule and quotient rule, we get
[tex]\dfrac{dy}{dx}=\dfrac{\sqrt{x-1}\dfrac{d}{dx}(x)-x\dfrac{d}{dx}(\sqrt{x-1})}{(\sqrt{x-1})^2}[/tex]
[tex]\dfrac{dy}{dx}=\dfrac{\sqrt{x-1}(1)-x\dfrac{1}{2\sqrt{x-1}}\dfrac{d}{dx}(x-1)}{(x-1)}[/tex]
[tex]\dfrac{dy}{dx}=\dfrac{\sqrt{x-1}-\dfrac{x}{2\sqrt{x-1}}(1-0)}{x-1}[/tex]
[tex]\dfrac{dy}{dx}=\dfrac{\sqrt{x-1}-\dfrac{x}{2\sqrt{x-1}}}{x-1}[/tex]
[tex]\dfrac{dy}{dx}=\dfrac{\dfrac{2x-2-x}{2(x-1)^{\frac{1}{2}}}}{(x-1)}[/tex]
[tex]\dfrac{dy}{dx}=\dfrac{x-2}{2(x-1)^{\frac{3}{2}}}[/tex]
Therefore, the required derivative is [tex]\dfrac{dy}{dx}=\dfrac{x-2}{2(x-1)^{\frac{3}{2}}}[/tex].

En una heladería, la nave de envasado está a 12 *C y en el interior a 15*C bajo cero cuál es la diferencia de temperatura?
Answer:
La diferencia de temperatura es de 27 ºC.
Step-by-step explanation:
Los procesos de transferencia de calor se deben a la presencia de gradientes térmicos, es decir, diferencias de temperatura que implican transferencia de energía desde puntos a mayor temperatura a puntos a menor temperatura. Entonces, la diferencia de temperatura ([tex]\Delta T[/tex]), medida en grados Celsius, queda descrita por la siguiente fórmula:
[tex]\Delta T = T_{o}-T_{i}[/tex] (1)
Donde:
[tex]T_{o}[/tex] - Temperatura exterior, medida en grados Celsius.
[tex]T_{i}[/tex] - Temperatura al interior de la nave de envasado, medida en grados Celsius.
Si tenemos que [tex]T_{o} = 12\,^{\circ}C[/tex] y [tex]T_{i} = -15\,^{\circ}C[/tex], entonces la diferencia de temperatura es:
[tex]\Delta T = 12\,^{\circ}C-(-15\,^{\circ}C)[/tex]
[tex]\Delta T = 27\,^{\circ}C[/tex]
La diferencia de temperatura es de 27 ºC.
