The answer is 24. There is 2 width sides and 2 length sides. Let's say the width measurement is x. The 2 sides for width equals 2x. The 2 length sides equals 4x because there twice has long has the width which means that each length side is 2x. 2x plus 4x equals 6x. 6x=24 You divided 24 with 6 which gives you 4. That means that both width sides are 4 units long and the length sides are 8 units long. 4+4+8+8=24, 4 times 8=24

It is given that cos 0 = -0.4209 and 0° 0 < 360°. Calculato the values of 0​
beks73 [17]

Answer:

114.89 degrees

245.11 degrees

Step-by-step explanation:

cos is negative in the second and third quadrant ("pointing" on the x-axis to the left).

so, the first answer for the second quadrant is

114.89 degrees.

the answer for the third quadrant is then backwards the same angles from a full 360 degree rotation

360 - 114.89 = 245.11 degrees

I don't know how to solve this helpp
Aleksandr-060686 [28]

neverminding the jumbled lingo, is simply asking for the equation of the tangent line at that point, it says all tangents, well, there's only one passing there.

we can simply get the derivative of f(x) and take it from there.

f(x)=4-x^2+2x\implies \left. \cfrac{df}{dx}=-2x+2 \right|_{x=\frac{3}{2}}\implies -2(\frac{3}{2})+2\implies -1

since now we know the slope when x = 3/2, then we can just plug that into its point-slope intercept form, along with the coordinates.

(\stackrel{x_1}{\frac{3}{2}}~,~\stackrel{y_1}{7})~\hfill \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{7}=\stackrel{m}{-1}(x-\stackrel{x_1}{\frac{3}{2}}) \\\\\\ y-7=-x+\cfrac{3}{2}\implies y=-x+\cfrac{17}{2}
