What is the value for y? Enter your answer in the box.

Anna007 [38]

Answer:

y = 28

Step-by-step explanation:

since this is an Isosceles triangle (x - 5)° must be equal to 34°

x - 5 = 34

x = 39

the sum of interior angles in a triangle is equal to 180°

if the two angles 34 + 34 = 68

Then the third angle is 180 - 68 = 112°

4y = 112

y = 28

A group of five people are all working on the same mathematics problem. On the night before it is due, they call each other to d

UkoKoshka [18]

Answer:

Minimum number of calls = 10

Step-by-step explanation:

Lets name the five people as A,B,C,D and E.

On the night before ,each person talks to every other person atleast once that means A would talk to B,C,D and E atleast once.

Lets start with A. He would talk to other 4 people which means there would be 4 phone calls made.

Now lets take B. He can talk to A,C,D and E. But A has already talked to C therefore to get minimum number of phone calls , B need not call A again. So he calls only C,D and E.

In case of C using similar logic he need to talk to only D and E.

For D , he talks to E alone.

E does not have to talk to anyone as he has already talked to everyone atleast once.

Total calls = 4 + 3 + 2 + 1

= 10

Consider the points.

miskamm [114]

Answer:

6 units

Step-by-step explanation:

Use the distance formula, $\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}$ .

Plug the x and y values from the given points into the distance formula:

$\sqrt{([-4]-2)^{2}+(5-5)^{2}}$ .

Solve the square root:

$\sqrt{36}$ = $\sqrt{6^{2}}$ = $6$

Write a quadratic function with zeroes 0 and 8.

Jlenok [28]

Answer:

$x^2-8x=0$

Step-by-step explanation:

the quadratic function should be as follows:

$x^2-8x=0$

Now let's confirm that the zeros of the function are 0 and 8

$x^2-8x=0=x(x-8)=0$

Therefore we can see that if x = 0

$0^2*8*0=0\\0=0$

the equation is fulfilled

And we also have $(x-8)$

for this expresion to be equal to zero:

$x-8=0\\x=8$

thus, if x = 8

$8^2-8*8=0\\64-64=0\\0=0$

the equation is also fulfilled

The zeros of the quadratic function $x^2-8x=0$ are 0 and 8.
