Answer:

according to basic proportionality theorem

$\qquad\sf {:}\longrightarrow 25/35=x/63$

$\qquad\sf {:}\longrightarrow 5/7=x/63$

$\qquad\sf {:}\longrightarrow 7x=63×5=315$

$\qquad\sf {:}\longrightarrow x=315/7=45$

Make a table of values for the function rule. then graph the function. y=-x²+4

lakkis [162]

Answer:

check the attached picture

Step-by-step explanation:

Given function is $y=-x^2+4$ .

Now we need to make a table of values for the function rule then graph the function.

We are free to plug any values of x like -3,-2,-1,0,1,2,3,... etc becaues domain of polynomial function is all real numbers.

Let's plug x=1 into given function to find the y-value

$y=-x^2+4$

$y=-(1)^2+4$

$y=-1+4$

$y=3$

Hence the first point is (1,3).

Same way we can find few more points to complete the table then graph those points and connect them to get the final graph.

The question is in the picture. Plz helppp it is due tonight

Mkey [24]

Answer:

Step-by-step explanation:

We're given one equation, we have to find the other equation and solve each for 200, and whichever has the lower x is the winner

for Jayden we are given

$(0, 48), (1, 56), (2, 64), (3, 72), (4, 80)$

This looks to be a line. The y values are each separated by a common difference

We can use two points to describe the line

$m = \frac{y_2-y_1}{x_2-x_1} = \frac{80-48}{4-0} = \frac{32}{4} = 8\\ K = 8m + b\\48 = 8(0) + b\\b = 48\\so\\K = 8m + 48$

Now we can set both $K = 8m + 48$ and $K = m^2 + 10$ equal to 200

$200 = 8m + 48\\152 = 8m \\m = \frac{152}{8} = 19$

$200 = m^2 + 10\\m^2 = 190\\m = \sqrt{190} = 13.784$

A circle is divided into three arcs of measures x 2x and 3x what’s the value of x

lidiya [134]

Answer:

60°

Step-by-step explanation:

This questions tests our knowledge on arcs and arc measures.

-Arc measure is the angle that an arc makes with the circle's center.

-The arc measure is proportional to the arc.

#The sum of the 3 arcs is x+2x+3x=6x

Given a circle has 360°, the arc measurement x can be calculated as:

$[x+2x+3x]=360\textdegree\\\\6x=360\textdegree\\\\x=60\textdegree$

Hence, the arc measurement x is 60°
