A) AB is parallel CD from graphic;
b) m AB = (3-1)/(2-0) => m AB = 1;  m CD = (7-5)/(6-4) => m CD = 1 => m AB = m CD => AB is parallel CD;

Answer:

Step-by-step explanation:

1). Vertical intercept of the graph = Point at which the graph intersects the y-axis.

Therefore, vertical intercept is y = 1000.

In this situation vertical intercept means the initial dose of the drug taken = 1000 mg.

2). From the graph attached, point (x, y) represents,

x = Time 't' or duration

y = concentration of the drug after time 't'

Point (0, 1000) represents concentration = 1000 mg of the drug after t = 0 hour

Similarly, (1, 750) represents concentration = 750 mg after t = 1 hour

Therefore, fraction of drug remained = \frac{750}{1000}

                                                              = \frac{3}{4}

3). Let the equation, representing the concentration of the drug and time is,

y=a(b)^t

Here, a = Initial amount of the drug (at t = 0 hours)

            = 1000 mg

At (t = 1 hours), concentration of the drug = 750 mg

y=1000(b)^t

750=1000(b)^1

b=\frac{750}{1000}

b=\frac{3}{4}

Therefore, equation will be,

y=1000(\frac{3}{4})^t

Are the triangles congruent why or why not
maxonik [38]

Answer:

The triangles are congruent by either Angle Side Angle (ASA) or Angle Angle Side (AAS).

Further Explanation:

The congruent triangles are those in which all the corresponding angles and the sides are equal.

There are many congruency rules and are as follows.

1. Angle Angle Side (AAS)

2. Angle Side Angle (ASA)

3. Side Side Side (SSS)

4. Side Angle Side (SAS)

Explanation:

The sum of all the angle of a triangle is {180^ \circ }180

∘

.

In triangle ABC the sum of all angle is {180^ \circ }180

∘

.

\begin{lgathered}\begin{aligned}\angle A+\angle B+\angle C&={180^\circ}\\{42^\circ}+{53^\circ }+\angle C&={180^\circ }\\\angle C&={180^\circ }-{95^\circ }\\\angle C&={85^\circ }\\\end{aligned}\end{lgathered}

∠A+∠B+∠C

42

∘

+53

∘

+∠C

∠C

∠C

=180

∘

=180

∘

=180

∘

−95

∘

=85

∘

In triangle RMQ the sum of all angle is {180^ \circ }180

∘

.

\begin{lgathered}\begin{aligned}\angle R+\angle M+\angle Q&=180^{\circ}\\42^{\circ}+\angle M+85^{\circ}&=180^{\circ}\\\angle M&=180^{\circ}-127^{\circ}\\\angle M&=53^{\circ}\end{aligned}\end{lgathered}

∠R+∠M+∠Q

42

∘

+∠M+85

∘

∠M

∠M

=180

∘

=180

∘

=180

∘

−127

∘

=53

∘

Consider the triangle ABC and triangle RMQ.

\angle A=\angle R={42^\circ }∠A=∠R=42

∘

Side AB = RM

\angle B=\angle M∠B=∠M

Therefore, the triangle ABC is congruent to triangle RMQ.

The triangles are congruent by either Angle Side Angle (ASA) or Angle Angle Side (AAS).

What is the value of k in the equation below? 5k - 2k = 12? 1 1/5, 1 5/7, 3, 4
valkas [14]
Hi there!

5k - 2k = 12
Solve for K
3k = 12
Divide both sides by 3
3k/3 = 12/3
k = 4
The correct answer is : 4
