Answer:

54°

Step-by-step explanation:

$m\angle CDE = \frac{1}{2} \{237 \degree - (360 \degree -237 \degree ) \} \\ \\ = \frac{1}{2} \times \{237 \degree - 123 \degree \} \\ \\ = \frac{1}{2} \times 114 \degree \\ \\ = 54 \degree \\ \\ \huge \red{ \boxed{ \therefore \: m\angle CDE =54 \degree}}$

Function A is a quadratic function with a vertex at (3, 4) and a leading coefficient of -1 Function B has the equation y = |x +

skad [1K]

With the information given, we deduce that the parabola is

$y=-(x-3)^2+4 = -(x^2-6x+9)+4 = -x^2+6x-5$

Reflecting a function over the x axis means to change its sign. After the reflection, the parabola becomes

$y=x^2-6x+5$

And to shift down a function, you subtract the shift from the equation: the equation becomes

$y=x^2-6x+5-2=x^2-6x+3$

Similarly, the other function is reflected over the x axis (sign change) and shifted up 3 (add 3 to the equation):

$|x+2|\mapsto -|x+2|\mapsto -|x+2|+3$

In order to compute the y intercept, we simply have to evaluate the functions at x=0: for the parabola we have

$y(0)=3$

For the other function, we have

$y(0)=-|2|+3=-2+3=1$

I’m completely lost can anybody help solve this

Marizza181 [45]

Answer:

$\huge\boxed{x=54^o}$

Step-by-step explanation:

<em>Look at the picture.</em>

<em />

We have:

$l=108^o$

Therefore

$2\alpha=108^o$ <em>divide both sides by 2</em>

$\dfrac{2\alpha}{2}=\dfrac{108^o}{2}\\\\\alpha=54^o$

Please help ASAP I don’t understand

Answer:

88 square inches

Step-by-step explanation:

if the entire square was shaded it would be 14 x 12 (as best as i can see)

the "cut out" or white part of the square is 8 x 10

Entire squre - cutout white part

14 x 12 - 8 x 10

168 - 80

88 sq in

In one school, half of all students who like math like science as well. Also, in that school, a third of all students who like s

Nimfa-mama [501]

Answer:

2/3

Step-by-step explanation:

If we have 'x' students who like math and 'y' students that like science, we can formulate that:

Half of x likes math and science, and also one third of y likes math and science, so:

(1/2) * x = (1/3) * y

x / y = (1/3) / (1/2)

x / y = (1/3) * 2 = 2/3

So the ratio of the number of students who like math to the number of students who like science is 2/3
