Answer:
After 10 weeks, Susan will have $295 and CiCi will have $259.
Step-by-step explanation:
Susan: y= 65+23x
CiCi: y = 119+14x
65+23(6)=203
119+14(6)=203
After 6 weeks, Susan and CiCi will both have $203 in their accounts.
65+23(10)=295
119+(14)(10)=259
Therefore, After 10 weeks, Susan will have $295 and CiCi will have $259.
If x2 + y2 + z2 = 9, dx dt = 3, and dy dt = 9, find dz dt?
Answer:
dz/dt = -(3x + 9y)/z
Step-by-step explanation:
x² + y² + z² = 9
2x dx/dt + 2y dy/dt + 2z dz/dt = 0
x dx/dt + y dy/dt + z dz/dt = 0
x * 3 + y * 9 + z dz/dt = 0
so
dz/dt = -(3x + 9y)/z

f(x) = -2x4 + 6x3 - 3x + 11 when x = 4
(
-
Answer:
f(4) = -129
Step-by-step explanation:
Substitute the value of x which is 4
f(x) = -2x4 + 6x3 - 3x + 11
f(4) = -2(4)4 + 6(4)3 - 3(4) + 11
f(4) = -2(256) + 6(64) - 12 + 11
f(4) = -512 + 384 - 1
f(4) = -128 - 1
f(4) = -129

It takes 79 pounds of seed to completely plant a 12-acre field. How many acres can be planted per pound of seed?
Answer:
0.152 acres
Step-by-step explanation:
Given the information that 79 pounds of seed means you can plant 12 acres of field, we can set the two equal to each other:
79 pounds of seed = 12 acres
Now, we just need to use 1 pound of seed to solve for the amount of acres that can be planted per that one pound:
1 pound seed ([tex]12acres/79pounds[/tex]) = 0.152 acres
The line y = 4x + c passes through (1,7), find the value of c
Answer:
c = 3
Step-by-step explanation:
y = 4x + c
to find c substitute (1, 7 ) into the equation
7 = 4 + c ⇒ c = 7 - 4 = 3
6. Write and solve an equation to find the value of x. (Example 3) 120° X (2x) ico
Answer:
120° = 2(x)°
120/2 = x
60 = x
Step-by-step explanation:
120° = 2(x)° because the two lines cross forming an x shape and angles opposite to each other are always equal in lines forming x shapes. Hence you can form an equation as shown above and solve it for x. Since the above equation is a linear one you can simply solve it by bringing all the numbers to one side. since 2 is multiplied on the right hand side, when we bring it to the left it has to be divided.

Step-by-step explanation:
0.25 x 63 = 15.75
0.05 x 63 = 3.15
----------------------------
0.25 x 50 = 12.50
+ = $13.15
0.05 x 13 = 0.65
----------------------------
0.25 x 25 = 6.25
+ = $8.15
0.05 x 38 = 1.90
----------------------------
0.25 x 30 = 7.50
+ = $9.15
0.05 x 33 = 1.65
--------------------------
0.25 x 35 = 8.75

Which equation represents exponential growth? A)Y=2x or B)Y=3(5)^ or C)y=4x2 or D)Y= 2(0.5)x
Answer:
B)
Step-by-step explanation:
Why A Doesn't Work:
y=mx+b is a linear equation.
y=2x, y=2x+0 which is a linear equation.
Why C doesn't work:
Anything with x² in it is a parabola. Anything.
4x² is a parabola, not an exponential equation.
Check for yourself on Desmos.
Why D doesn't work:
2(0.5)x
2(0.5) = 1
(1)x = 1x
y=1x, y = 1x+0 = LINEAR
Why B Works:
I do not understand what B is supposed to be, but I suppose it is correct by using the process of elimination.
Hope this helps :)

c) 3+3+4+4=14 units
d) 12 units squared
question 3
if their slopes are the same, they are parallel.
if the lines do not intersect graphically, they are parallel.
if the slopes multiply to -1, they are perpendicular.
if the degree made by the intersection is 90 degrees, the lines are perpendicular.

65% = 4875
divide both by 65
1% = 75
multiply by 100
100% = 7500
Marie built a sand castle that is made a
of two rectangular prisms. If there are
2,000 cubic inches of sand in a bag of
sand, how much sand was left after
Marie built her sand castle? Explain
how you found your answer.
Answer:
Are there any measurements for the size of the prisms? I think we need more info for this. I'll delete this when you answer and upload a new one :)
Step-by-step explanation:
The amount of sand left after building the sand castle is 290 inches³.
What is Rectangular Prism?Rectangular prism is a three dimensional shape which consist of six faces. The two faces are at the top and bottom and the other faces are lateral faces.
We have to find the volume of each of the rectangular prism to know how much sand is used to make the castle.
Volume of a rectangular prism = l × w × h
where l, h and w are length, height and width of the prism respectively.
Volume of larger prism = 15 × 15 × 6
= 1350 inches³
Volume of smaller prism = 9 × 8 × 5
= 360 inches³
Total volume of the castle = 1350 + 360 = 1710 inches³
Remaining sand = 2000 - 1710 = 290 inches³
Hence the sand that remains is 290 inches³.

let the vertices on either side of the 0 be A and B
then let the vertex opposite of O be C
First, angle ACB will be equal to 90° as it is the angle that lies on the same arc as the diameter. From there you can find angle y with angle A+ angle B+ Angle C=180°
then you can find the angle complementary to x with the same formula then you can subtract that angle with 90° to get x.

IF Cos 3A =Sin7A then A is
Answer: A=0.8767601914
First you need to find the value of cos(3) and sin(7) which happens to be cos(3)=0.9986295348A and sin(7)=0.1218693434A. So you have the numbers, then what do you do with them? Well you will want to subtract them both and find the difference between them which should be the value of A. so 0.9986295348-0.1218693434=0.8767601914 so A=0.8767601914 if you want you can simplify this...

write an algebraic expression for the following phrases.
1. 34 more than a number __
2. twice a number minus 12 __
3. 16 less than a number __
4. a number increased by 45 __
5. the difference of 23 and a number __
6. decrease a number by 7 and multiply by 6 __
7. 4 tikes a number subtracted from 78 __
8. increase the product of a number and 4 by 10 __
9. the sum of 3 times a number and 2 __
10. a number times the difference of 13 and a number. __
Answer:
1. x + 34
2. 2x - 12
3. x - 16
4. x + 45
5. 23 - x
6. 6(x - 7)
7. 78 - 4x
8. 4x + 10
9. 3x + 2
10. x(13 - x)
Step-by-step explanation:
For problems like this in the future, pay attention to the order of words, and how they go together! For example- "the difference of 23 and a number" means to subtract a number from 23, whereas "the difference of a number and 23" would mean to subtract 23 from the number. Words like "increase" and "sum" both mean addition; "product" and "times" both mean multiplication; "difference" and "less" mean subtraction. Just keep these in mind (and watch for context)!
