Answer:

Option B is correct.

Step-by-step explanation:

We have been given a point on unit circle defined by real number theta.

So, tan theta is the given by: $tan\theta=\frac{y}{x}$

Equation of unit circle is $x^2+y^2=1$

Where 1 is the radius.

Therefore, Option B is correct that is $tan\theta=\frac{y}{x}$

Write a cubic function whose graph goes through the points: (-5, 0) (1, 0) (2, -2) (4, 0)

Free_Kalibri [48]

Answer:

f(x) = $\frac{1}{7}(x+5)(x-1)(x-4)$

Step-by-step explanation:

Let the equation of the give cubic function is,

f(x) = p(x - a)(x - b)(x - c)

Here, a, b, c and d are the x-intercepts of the given graph.

Since, x-intercepts given in the graph are x = -5, 1 and 4,

Equation of the curve will be,

f(x) = p(x + 5)(x - 1)(x - 4)

Since, the graph of this function passes through (2, -2) also

-2 = p(2 + 5)(2 - 1)(2 - 4)

-2 = -p(14)

p = $\frac{2}{14}$

p = $\frac{1}{7}$

Therefore, equation will be,

f(x) = $\frac{1}{7}(x+5)(x-1)(x-4)$

jeyben [28]

Answer:

y=2x-23

Step-by-step explanation:

m=(-9+7)/(7-8)=-2/-1=2

y=2x+b

-7=2(8)+b

-7-16=b

b=-23

y=2x-23

60 total fourth graders and 43 are girls. To find the number of boys, subtract.

60 - 43 = 17 boys

If 5 girls were absent, subtract.

43 - 5 = 38 girls present

If 4 boys were absent, subtract.

17 - 4 = 13 boys present

Therefore, there were 13 boys present.

Best of Luck!

If XYZ ~ EDF, the measure of angle F is _____ a0°.

hoa [83]

Answer:

63° (same as Z)

Step-by-step explanation:

The question indicates that ΔXYZ is similar to ΔEDF.

By definition, when we indicate that triangle XYZ is similar to the triangle EDF, the order of the letters is important and match the congruent angles.

So, ∠X = ∠E, ∠Y = ∠D and ∠Z = ∠F

It's hard to see because the angles are quite similar in opening (56°, 63° and 61°), and the drawing doesn't seems to be to scale.

But according to the naming convention: ∠Z = ∠F

Since ∠Z = 63°, ∠F = 63°
