Answer:

∠ ABD = 49°, ∠ CBD = 28°

Step-by-step explanation:

∠ ABD + ∠ CBD = ∠ ABC , substitute values

3x + 22 + 5x - 17 = 77 , that is

8x + 5 = 77 ( subtract 5 from both sides )

8x = 72 ( divide both sides by 8 )

x = 9

Thus

∠ ABD = 3x + 22 = 3(9) + 22 = 27 + 22 = 49°

∠ CBD = 5x - 17 = 5(9) - 17 = 45 - 17 = 28°

Answer:

-18+(-90) = -18-90 = -108

Answer:-108

Step-by-step explanation:

Answer: Rotate 180 degrees around the origin

You can do this clockwise or counterclockwise.

Whenever we move from one quadrant to the complete opposite quadrant like this, we perform a 180 degree rotation. Connect any preimage point to its corresponding image point, and this segment will go through the origin. This works because the origin is the center of rotation, and only works with 180 degree rotations.

Answer:

$450

Step-by-step explanation:

You want to calculate the interest on $3000 at 3% interest per year after 5 year(s).

The formula we'll use for this is the simple interest formula, or:

Where:

P is the principal amount, $3000.00.

r is the interest rate, 3% per year, or in decimal form, 3/100=0.03.

t is the time involved, 5....year(s) time periods.

So, t is 5....year time periods.

To find the simple interest, we multiply 3000 × 0.03 × 5 to get that:

The interest is: $450.00

Usually now, the interest is added onto the principal to figure some new amount after 5 year(s),

or 3000.00 + 450.00 = 3450.00.

Explication étape par étape:

Étant donné la fonction polynomiale f (x) = -2x² + 4x + 6. Pour vérifier si f (-1) est un facteur de l'expression, nous devons montrer que f (-1) est équivalent à zéro. S'il est nul, donc x + 1 est un facteur du polynôme.

Preuve

f (x) = -2x² + 4x + 6

f (-1) = -2 (-1) ² + 4 (-1) +6

f (-1) = -2 (1) -4 + 6

f (-1) = -2-4 + 6

f (-1) = -6 + 6

f (-1) = 0

Puisque f (-1) = 0, donc x + 1 est un facteur du polynôme.

Ensuite, il faut obtenir l'autre racine du polynôme. Pour obtenir cela, nous devons factoriser la fonction polynomiale donnée.

Soit f (x) = 0

-2x² + 4x + 6 = 0

multiplier par -1

2x²-4x-6 = 0

diviser par 2

x²-2x-3 = 0

x²-3x + x-3 = 0

x (x-3) +1 (x-3) = 0

(x + 1) (x-3) = 0

x + 1 = 0 et x-3 = 0

x = 1 et x = 3

Par conséquent, l'autre racine du polynôme en dehors de 1 est x = 3

edge 2021

Answer:

1) The dependent variable is the monthly charge and the independent variable is the $110 to open the membership.

2)The dependent variable is the monthly charge because it will change depending on how many months you plan to keep your membership.

3)This relationship is linear because it will go up by $30 every month.

4)You could create a graph off of this information because all you would need to do is graph the cost each month.

5)I would need the number of month that I would keep the membership going and the amount that i have already paid.

Step-by-step explanation:

====================================================

Explanation:

Check out the diagram below. I recreated the diagram in your textbook, but I added on a few other points and segments.

Point E is the midpoint of segment AB. Segment OE is perpendicular to AB.

Point F is the midpoint of CD. Segment OF is perpendicular to CD.

Right triangle AOE forms with OA = 10 as the hypotenuse (radius of the circle) and AE = 8, since E cuts AB in half.

Use the pythagorean theorem to find that...

a^2+b^2 = c^2

(AE)^2 + (OE)^2 = (OA)^2

8^2 + (OE)^2 = 10^2

64 + (OE)^2 = 100

(OE)^2 = 100-64

(OE)^2 = 36

OE = sqrt(36)

OE = 6

--------------------

Because chord CD is the same length as chord AB, this means the chords are the same distance from the center point O.

So, OE = OF = 6

Since we have rectangle OEPF, the opposite sides are congruent and we can say OF = EP = 6

Now focus on right triangle OEP. Use the pythagorean theorem again

a^2+b^2 = c^2

(OE)^2 + (EP)^2 = (OP)^2

(6)^2 + (6)^2 = (OP)^2

72 = (OP)^2

(OP)^2 = 72

OP = sqrt(72)

OP = sqrt(36*2)

OP = sqrt(36)*sqrt(2)

OP = 6*sqrt(2)
