3 0

Answer:

C. 57

Step-by-step explanation:

all triangles add up to 180. the tick marks show that ∠D and ∠ E are congruent so you do this and solve for x:

(4x + 1) + (4x + 1) + (5x - 4) = 180

13x - 2 = 180

13x = 182

x = 182/13

x = 14

4(14) + 1 = 57

The function f(x)= --x is shown on the graph.
sertanlavr [38]

Answer:

Option (3).

Step-by-step explanation:

Attached figure is the graph of a function,

f(x) = -\sqrt{-x}

Since domain of any function is the set of all possible input values of the function,

Therefore, Domain of the function is,

Domain : x ≤ 0 Or (-∞, 0]

And range of the function is the set of all possible output values (y-values) of the function.

Therefore, Range of the function will be,

Range : y ≤ 0 Or (-∞, 0]

Therefore, Domain and range of this function is same.

Option (3) will be the answer.

Researchers have found that after 25 years of age the average size of the pupil in a
laila [671]

Answer:

At 25 = 6.8612mm

At 50 years = 5.422mm

Step-by-step explanation:

Equation,

d = 2.115Logₑa + 13.669

d = diameter of the pupil

a = number of years

Note : Logₑa = In a (check logarithmic rule)

d = 2.115Ina + 13.669

1. At 25 years,

d = -2.115In25 + 13.669

d = -2.115 × 3.2188 + 13.669

d = -6.807762 + 13.669

d = 6.8612mm

At 25 years, the pupil shrinks by 6.86mm

2. At 50 years,

d = -2.1158In50 + 13.669

d = -2.1158 * 3.912 + 13.669

d = -8.2770 + 13.699

d = 5.422mm

At 50 years, the pupil shirks by 5.422mm

To save this question, I had to plug in the values into the equation.

Solving for Logₑa might be difficult, so instead I used Inx which is the same thing. Afterwards, i substituted in the values and solve the equation for each years.

A pitcher contains 2 liters of liquid. Jin pours 368 milliliters of this liquid into a test tube.
8090 [49]

Answer:

1,632 liters of liquid remain in the pitcher.

Step-by-step explanation:

Given that a pitcher contains 2 liters of liquid, and Jin pours 368 milliliters of this liquid into a test tube, to determine how much liquid is left in the pitcher the following calculation must be performed:

368 milliliters = 0.368 liters

2 - 0.368 = X

1.632 = X

Therefore, 1,632 liters of liquid remain in the pitcher.
