Olenka [21]3 years ago

Let , missing value(_)=A

As, it is given that ,

CosA=\frac{6}{19}\\\\ Cos A=0.3158\\\\ A=72 {\text{Degree}}

To convert the value of A into Radians,

360°=2 π Radians

1 {\text{degree}}=\frac{\pi}{180}\\\\72 {\text{Degree}} =\frac{72\times 22}{180 \times 7}\\\\=1.2571

So, missing value to the nearest hundredth= 1.26 Radians

reflect (7,4) across the x-axis then reflect the result across the y-axis what are the coordinates of the final point
Andrews [41]

The coordinates of the final point after the two reflections is (-7, -4)

<h3>How to reflect a point across an axis?</h3>

For a point (x, y), a reflection across the x-axis gives the point (x, -y), while for a point (x, y) a reflection across the y-axis gives (-x, y).

In this case, we have the point (7, 4), first we reflect across the x-axis, so we get the point (-7, 4).

Now we reflect across the y-axis, so the sign of the y-component changes, and we get (-7, -4)

So the coordinates of the final point after the two reflections is (-7, -4).

Iteru [2.4K]

Answer:

The answer is B - A high correlation between two or more independent variables.

Step-by-step explanation:

There are many factors that shows the possible presence of multicollinearity in a regression analysis. Multicollinearity occurs when independent variables in a regresssion model are correlated; the independent variables as their names implies is to be fully independent (on their own).

Based on the options; multicollinearity occurs when there is a high correlation between two or more independent variables.

I need to know the surface area of these
anastassius [24]

9514 1404 393

Answer:

  245 cm²

Step-by-step explanation:

The surface area of a cone is given by ...

  SA = πr(r +s) . . . . where r is the radius, and s is the slant height

Filling in the given values, we have ...

  SA = (3.14)(3 cm)(3 cm +23 cm) = (3.14)(3)(26) cm² ≈ 245 cm²

The surface area of the cone is about 245 cm².
