Answer:
Kindly check explanation
Step-by-step explanation:
Given the data below:
Time, t (hours)__1.0__1.5__2.0__2.5__3.0
C(t) (mg/mL)__0.35_0.26_0.20_0.14_0.09
Average change of C with respect to t over the interval :
(i) [1.0, 2.0] (ii) [1.5, 2.0] (iii) [2.0, 2.5] (iv) [2.0, 3.0]
Average change = ( change in C / change in t) = C2 - C1 / t2 - t1
1) [1.0, 2.0]
C at t = 1 = 0.35 ; C at t = 2 = 0.20
(0.20 - 0.35) / (2 - 1) = - 0.15 / 1 = - 0.15 mg/mL hr
11) [1.5, 2.0]
(0.20 - 0.26) / (2.0 - 1.5) = - 0.06 / 0.5 = - 0.12 mg/mL hr
111) [2.0, 2.5]
(0.14 - 0.20) / (2.5 - 2.0) = - 0.06 / 0.5 = - 0.12mg/mL hr
iv) [2.0, 3.0]
(0.09 - 0.20) / (3.0 - 2.0) = - 0.11 / 1.0 = - 0.11 mg/mL hr
need a answer for all of them
Which led to the formation of oceans after water on Earth’s surface evaporated?
Answer:
The sun released a strong burst of water vapor. As Earth cooled, water in the atmosphere condensed. Materials collided due to strong gravitational forces. The ozone layer formed to protect against harmful UV ray exposure

1. Is a blender a convection,conduction,or a radiation? please help
Answer:
Convection! :)
Step-by-step explanation:
Solve
y
= x2 + 23 for x.
O A. x= y - 23
O B. = +Jy + 23
O C. X = +VÝ - 23
D. X = y +23
Answer:
x = ±√(y - 23)
Step-by-step explanation:
y = x^2 + 23 may be solved for x as follows:
Subtract 23 from both sides, to isolate x^2:
x^2 = y - 23
Take the square root of both sides. We get:
x = ±√(y - 23)
Given f(x) = |X - 9|.The vertex of the function moves from (0,0) nine units where?
left
right
up
down
Answer:
RightStep-by-step explanation:
Given function
f(x) = |x - 9|Let's try point x = 0
f(0) = | 0 - 9 | = | -9 | = 9So the vertex moves right

Quadrilateral EFGH is a scaled copy of quadrilateral ABCD. Select ALL of the true statements.
A. Segment EF is twice as long as segment AB, True or False
B. Segment CD is twice as long as segment FG. True or False
C. The measure of angle HEF is twice the measure of angle DAB. True or False
D. The length of segment EH is 16 units. True or False
E. The measure of angle BCD is the same as the measure of angle GFE. True or False
Answer: b,e
Step-by-step explanation:
1. In part (b) of the example, why isn't AB a correct answer? 2. In part (c) of the example, would KJL be an appropriate answer?
Answer:
Step-by-step explanation:
1. AB isn't a correct answer because it only refers to the part of the line between point A and point B. This is incorrect because it doesn't represent the whole line which goes on infinity past point A (as seen by the arrow).
2. KJL would not be an appropriate answer because the points must be listed in the same order that they appear in direction of the line. The angle shown is angle K so K should be the middle letter as it is the middle point with the angle. KJL would not be appropriate because it would refer to the angle J if there was another line between J and L.
Hope this helped!

1. what are the corrospoding parts of these two traingles? Write the corresponding angles and corresponding sides. 2. Assuming these triangles are simular, use the labels to write the ratios of corresponding sides that are proportional 3. Assuming these triangles are simular, write three statements relating the angle that are congruent
Answer:
See below.
Step-by-step explanation:
1. Look at the marks on the angles of both triangles.
Angles C and F have a single mark (that looks like an arc). They are congruent.
Angles A and D have a double mark (that look like arcs). They are congruent.
Angles B and E have a triple mark (that look like arcs). They are congruent.
Each pair of congruent angles is a pair of corresponding angles.
Corresponding angles:
<C and <F
<A and <D
<B and <E
For corresponding sides, we do this.
First, we write a statement of similarity.
Triangle ABC is similar to triangle DEF.
The statement of similarity must have the corresponding angles in the same order.
The order ABC and the order DEF matches corresponding angles.
The corresponding sides have the vertices of corresponding angles as their endpoints.
Corresponding sides:
AB and DE
BC and EF
AC and DF
2. For similar triangles, the ratios of the lengths of corresponding sides are equal.
The ratios of the lengths of corresponding sides are equal:
AB/DE = BC/EF = AC/DF
3.
<A is congruent to <D
<B is congruent to <E
<C is congruent to <F
Find the distance between the points E(3,7)and(6,5).find the exact distance between the two points ?
Step-by-step explanation:
Let the distance points E(3,7) and F(6,5)
Distance between EF = √[(x2-x1)²+(y2-y1)²]→Formula
Here, x1 = 3, y1 = 7
x2 = 6 , y2 = 5
Now,
Put all the values in distance formulae:
AB = √[(6-3)²+(5-7)²]
= √[(4)²+(2)²]
= √[(4*4)+(2*2)]
= √[16+4]
= √[20] = 2√5 Units.
Answer:- Hence, the distance between two points E(3,7) and F(6,5) is 2√5 Units.
On January 1, 2009, Jessica owed $10,212 to her friend Sam, who was kind enough not to charge Jessica any interest. Each month during 2009, Jessica paid Sam some of the money she owed. If Jessica still owed Sam $6,612 on January 1, 2010, what was the average amount of Jessica's monthly payments?
Answer:
551
Step-by-step explanation:
6612 divided by 12 ( number of months) =551
if a/b = 4/3 and b/c = 2/3, what is a,b, and c?
Answer:
.
Step-by-step explanation:
[tex] \frac{a}{b} = \frac{4}{3} [/tex]
[tex] \frac{b}{c} = \frac{2}{3} [/tex]
to give b from both equation the same value
[tex] \frac{a}{b} = \frac{4}{3} \times \frac{2}{2} = \frac{8}{6} [/tex]
[tex] \frac{b}{c} = \frac{2}{3} \times \frac{3}{3} = \frac{6}{9} [/tex]
a:b:c = 8:6:9
a = 8
b = 6
c = 9

Find the slope intercept form of the equation of the line through the points(2,-4) parallel to the line 8x+2y+2=0
Answer:
y = -4x + 4
Step-by-step explanation:
8x+2y+2=0
turn that into slope intercept form:
y = -4x - 1
a parallel line has the same slope, but different y-intercept
y = -4x + b
put (2,-4) into the equation
-4 = -4(2) + b
you get b=4
final product:
y = -4x + 4
