Answer:

a=2

b=2

Step-by-step explanation:

This is a special 45-degree right triangle. Two angles equal 45 degrees, and then there is a right triangle. In these triangles, the hypotenuse is equal to [tex]k*\sqrt{2}[/tex] where k is equal to the legs (a and b). So, to find the legs divide [tex]k*\sqrt{2}[/tex] by [tex]\sqrt{2}[/tex]. This equals 2, and since a and b are congruent both a and b equal 2.

Answer:

x = 7

Step-by-step explanation:

The image below shows the relationship between secants chords and tangents.

Imagine that the letters in the image represent the numbers in the actually problem

E would equal 9

C would equal 12

and A would equal x

We would then use the same formula C² = E * ( E + A ) to solve for x , but once again instead of using letters we use the numbers in the problem

We would have 12² = 9( 9 + x )

we now solve for x

Step 1 simplify and distribute

12²=144

9 * 9 = 81

9 * x = 9x

we would then have 144 = 81 + 9x

step 2 subtract 81 from each side

144 - 81 = 63

81 - 81 cancels out

we now have 63 = 9x

step 3 divide each side by 9

63 / 9 = 7

9x / 9 = x

we're left with x = 7

Answer:

y= -5/2x + 3/2

Step-by-step explanation:

(3,-6). y=mx+b or -6=-5/2 × 3+b, or solving for b: b=-6-(-5/2)(3). b=3/2.

(-1,4). y=mx+b or 4=-5/2 × -1+b, or solving for b: b=4-(-5/2)(-1). b=3/2.

Plugging in the two points, hence y= -5/2x + 3/2

Answer:

A. 3/25

Step-by-step explanation:

From Marco: p(green marble) = 3/10

From Kira: p(blue) = 6/15 = 2/5

p(green marble & blue) = 3/10 * 2/5 = 6/50 = 3/25

Answer:

B

Step-by-step explanation:

Obviously the population is increasing.

(3297.44-2568.05)/2568.05 = .284... = 28.4% increase

(4234-3297.44)/3297.44 = .284 ... = 28.4% increase

B is the answer

Answer:

A = 175, B = π/6, C = 345

Step-by-step explanation:

The given variation of the volume in the tank and time includes are;

At t = 0 the volume in the tank, y = Maximum volume, [tex]y_{max}[/tex] = 520 gallons

At t = 6 the volume in the tank, y = Minimum volume, [tex]y_{min}[/tex] = 170 gallons

The function that models the situation is y = A·cos(B·x) + C

Given that the function that models the situation is the cosine function, we have;

A = The amplitude = (The maximum - The minimum)/2

∴ A = (520 - 170)/2 = 175

A = 175

The period = The time to change from maximum to minimum = 2 × The time to change from maximum (t = 0) to minimum (t = 6)

∴ The period = 2 × (6 - 0) = 12

The period = 12 seconds = 2·π/B

∴ B = 2·π/12 = π/6

B = π/6

C = The vertical shift = Th minimum + A = (The maximum + The minimum)/2

∴ C = (520 + 170)/2 = 345

C = 345

Answer:

-4/3

Step-by-step explanation:

if the triangle is anchored at (0, 0) you come down

from point ( 0, 48) to point ( 36, 0) so the slope is

y= rise/run = -48/ 36 = -4/3

oml, this is false. truely false!!

hope this helps ya! :)

Answer:

D 0.75

Step-by-step explanation:

There are a total of 4 pairs: White-Summer, Black-Summer, White-Winter, and Black-Winter. There are a total of 8 socks.

The probability of pulling a black sock or a summer sock is the number of all black or summer socks divided by the total number of socks.

The number of black or summer socks includes 1 pair of White-Summer, 1 pair of Black-Summer, and 1 pair of Black-Winter.

This makes for 6 black or summer socks.

Divide 6 by 8 to get 0.75

Answer:

A cube number is a number multiplied by itself 3 times.

Step-by-step explanation:

A cubed number looks like this: [tex]x^{3}[/tex]

The x is whatever number is being cubed.

The triangles ΔABC ≈ ΔBDC and ΔABC ≈ ΔADB are similar triangles. Then the correct options are B and C.

A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.

In a right-angle triangle, the measure of one angle will be 90 degrees.

If any two angle of the triangles are congruent, then the triangles will be a similar triangle.

In triangle ΔABC and ΔADB, we have

∠A = ∠A (common angle)

∠B = ∠D = 90° (right angle)

Then the triangle ΔABC and ΔADB are similar triangles.

In triangle ΔABC and ΔBDC, we have

∠C = ∠C (common angle)

∠B = ∠D = 90° (right angle)

Then the triangle ΔABC and ΔBDC are similar triangles.

Then the correct options are B and C.
