It is a constant function, y = -12

If you have to choose from linear and exponential, then you can go with linear function.

Hope it helps!

The equation y = 3*2^2 represents a linear function...

Suppose the probability that a randomly selected man, aged 55-59, will die of cancer during the course of the year is startfra

Romashka-Z-Leto [24]

The probability that a randomly selected man dies of cancer during the course of the year = $\frac{300}{100000}= \frac{3}{1000}=0.003$

The probability that a randomly selected man does not die of cancer during the course of the year = $1-0.003=0.997$

The probability that atleast one man of this age dies of cancer is the complement of the probability that no man dies of cancer. In equation form we can write:

Probability that atleast one man of this age dies of cancer = 1 - No man at this age dies of cancer

The probability that no man dies of cancer out of 1000 selected men = $(0.997)^{1000}=0.04956$ , rounded of to 5 decimal places

Thus the probability that atleast one man at this age dies of cancer = 1 - 0.04956 = 0.95044

Write (9 + 6i) − (1 + 3i) as a complex number in standard form.

777dan777 [17]

Answer:

8 +3i

Step-by-step explanation:

(9 + 6i) − (1 + 3i)

Distribute the minus sign

(9 + 6i) − 1 - 3i

Combine like terms

9-1 + 6i -3i

8 +3i

Given: Tangents LA and LB, m∠AOB=110°. Find: m∠ALO.

Yuri [45]

Answer:

The measure of angle ALO = 35°

Step-by-step explanation:

* Lets talk about the tangents to a circle drawn from a point

outside the circle:

- They are equal in length

- They are perpendicular to the radii at the point of tang-ency

- If we join the points of tang-ency withe the center of the circle

and join the outside point with center of the circle, we

formed two congruent triangles

* Now lets check our problem

- AL and LB are two tangents to the circle O ant points A and B

∴ LA = LB ⇒ (1)

- OA and OB are radii in circle O

∴ OA = OB ⇒ (2)

∴ OA ⊥ AL and OB ⊥ BL ⇒ radius and tangent

∴ m∠OAL = 90° , m∠OBL = 90

∴ m∠OAL = m∠OBL ⇒ (3)

* From (1) , (2) , (3)

- The two triangles LAO and LBO are congruent ⇒ SAS

- SAS is one case of congruence

∵ The lengths of two sides and the measure of the including

angle between them in one triangle equal to the

corresponding sides and angles in the second triangle,

then the two triangles are congruent

∴ m∠LOA = m∠LOB

∵ m∠AOB = 110°

∴ m∠LOA = m∠LOB = 110/2 = 55°

* In ΔLAO

∵ m∠ LAO = 90° , m∠LOA = 55°

∴ m∠ALO = 180 - (90 + 55) = 180 - 145 = 35°

* The measure of angle ALO = 35°
