Please help me with expression

Answer:

c = 121

Step-by-step explanation:

Given

t² - 22t

To complete the square

add ( half the coefficient of the t- term )² to t² - 22t

= t² + 2(- 11)t + (- 11)²

= t² - 22t + 121

with c = 121

Thus

t² - 22t + 121 = (t - 11)²

Answer:

3/28

Step-by-step explanation:

3/8 * 2/7 = 6/56 = 3/28

Answer:

1.)10  2.)0  3.)10

Step-by-step explanation:

1.) 4 (2) = 8 + 2 = 10

2.) 2(2) - 4/5 = 0

3.)2y + 11/-11 = +3y/-3y +1

2y - 3y = 1 - 11

-1y/-1 = -10/-1 = 10

Answer:

x=24

Step-by-step explanation:

Use Pythagorean Theorem to solve for x.

7^2+x^2=25^2

49+x^2=625

-49       - 49

x^2=576

sqrt sqrt

x=24

Given:

Two diameters intersect each other.

To find:

The correct statement regarding two adjacent arcs created by two  intersecting diameters.

Solution:

We know that, two diameter intersect each other at origin and measure of arc is equal to the corresponding angle generated by the intersection of diameters.

If two lines intersect each other then we get 4 angles and sum of any two adjacent angles is 180°.

It means the sum of any two adjacent central angles generated by the intersection of diameters is 180°.

So, the sum of two adjacent arcs created by two  intersecting diameters is 180°.

Therefore, the correct option is C.

Answer:

Jupiter to Sun = 7.688 * 10⁸km

Step-by-step explanation:

Given

Earth to Moon = 3.844 * 10⁵km

Jupiter to Sun = 2 * 10³ times Earth to Moon

Required

Determine the average distance from Earth to Moon

Jupiter to Sun = 2 * 10³ times Earth to Moon

Substitute 3.844 * 10⁵km for Earth to Moon

Jupiter to Sun = 2 * 10³ *  3.844 * 10⁵km

Collect Like Terms

Jupiter to Sun = 2 *  3.844 * 10³ * 10⁵km

Jupiter to Sun = 7.688 * 10³ * 10⁵km

Jupiter to Sun = 7.688 * 10⁸km

Hence, option C answers the question

Answer:

the answer is C

Step-by-step explanation:

Because if you look at the slope and find the rise over run you wil get 1/2 slope then next you have the dotted which means you have a < or > symbol. After that you see the gray shaded area is where the y is in terms with the equation. since the shaded area is above hte line that means the y must be greater than (>)  the line and not on it.

which gives us y>1/2x+1

Answer:

The center of the circle is:

Thus, option (2) is true.

Step-by-step explanation:

The circle equation is given by

[tex]\left(x-a\right)^2+\left(y-b\right)^2=r^2[/tex]

here,

Given the equation

[tex]\left(x-14\right)^2+\left(y+21\right)^2=64[/tex]

[tex]\mathrm{Rewrite}\:\left(x-14\right)^2+\left(y+21\right)^2=64\:\mathrm{in\:the\:form\:of\:the\:standard\:circle\:equation}[/tex]

[tex]\left(x-14\right)^2+\left(y-\left(-21\right)\right)^2=8^2[/tex]

comparing with the circle equation

[tex]\left(x-a\right)^2+\left(y-b\right)^2=r^2[/tex]

Therefore, the center of the circle is:

Thus, option (2) is true.

Answer:

6,10,or 30 is your answer

Answer:

y= 1/2x - 1

Step-by-step explanation:

TO FIND SLOPE: Count the rise over run. Rise= how much the next point RISES (on the y axis). Run= how much the next point RUNS (moves on the x axis)

TO FIND Y-INTERCEPT: Where the line meets the y axis. We see that the line crosses over on the -1.

Answer:

2.2222222

Step-by-step explanation:

Use a calculator

Answer:

a) [tex]\huge\boxed{\sf 77:100}[/tex]

b) [tex]\huge\boxed{\sf 23 : 77}[/tex]

Step-by-step explanation:

Total Juices box = 100

Juices boxed taken = 100 - 23 = 77

Juices boxes remaining = 23

[tex]\rule[225]{225}{2}[/tex]

Ratio of juice boxes taken to total juice boxes:

= 77 : 100

[tex]\rule[225]{225}{2}[/tex]

Ratio of juice boxes remaining, to juice boxes taken:

= 23 : 77

[tex]\rule[225]{225}{2}[/tex]

Step-by-step explanation:

Since sides AD and BC are parallel,

Angle BAD + Angle ADC = 180° (co-interior angles)

Therefore Angle ADC = 180° - 115° = 65°.

Answer:

Step-by-step explanation:

Since no diagram attached there are two possible options.

Option 1

The quadrilateral is parallelogram.

In this case ∠A and ∠D sum up to 180°, therefore:

Option 2

The quadrilateral is isosceles trapezoid.

In this case ∠A is congruent with ∠D, therefore:
