Answer:
The acceleration of object is -4 ms⁻²
Step-by-step explanation:
We are given:
Initial Velocity = 65 m/s
Final Velocity = 25 m/s
Time t = 10 seconds
We need to find acceleration.
The formula used to find acceleration is: [tex]Acceleration=\frac{Final\:Velocity-Initial\:Velocity}{Time}[/tex]
Putting value in the formula and finding acceleration:
[tex]Acceleration=\frac{Final\:Velocity-Initial\:Velocity}{Time}\\Acceleration=\frac{25-65}{10}\\Acceleration=\frac{-40}{10}\\Acceleration=-4\:ms^{-2}[/tex]
So, acceleration of object is -4 ms⁻²

9,-81, 729,-6561...
What is the common ratio?
Help which is the correct answer?
Answer:
[tex]r = -9[/tex]
Step-by-step explanation:
Given
[tex]Sequence: 9,-81, 729,-6561...[/tex]
Required
Determine the common ratio
The common ratio r is calculated using:
[tex]r = \frac{T_n}{T_{n-1}}[/tex]
Let [tex]n = 2[/tex]
So, we have:
[tex]r = \frac{T_2}{T_{2-1}}[/tex]
[tex]r = \frac{T_2}{T_1}[/tex]
From the sequence:
[tex]T_2 = -81[/tex]
[tex]T_1=9[/tex]
So, the equation becomes
[tex]r = \frac{-81}{9}[/tex]
[tex]r = -9[/tex]
Please please please can someone please help me with this problem. I don’t know what to do and I’m fairly certain I’m about to fail my math class...

bcdae============================================
Explanation:
The general form of a slope intercept equation is y = mx+b
m = slope
b = y intercept
Something like y = (-7/6)x + 1 matches with y = mx+b such that m = -7/6 is the slope and b = 1 is the y intercept. So that's why problem 1 matches with choice b (in column B).
Similar situations apply for problems 2 and 3
-----------
For problem 4, we can see the slope is m = -1, but unfortunately m = -1 isn't listed in column B. However, m = -7/7 is listed. So this is why problem 4 matches with choice a. This leaves problem 5 to match with choice e.
note: 6/7 = 12/14 after multiplying top and bottom by 2.
The volume of a cuboid is 40cm3.
The length is 2cm and the width is 4cm.
Work out the height of the cuboid.
Answer:
The height of the cuboid = 5 cm
Step-by-step explanation:
Explanation:-
Given that the volume of the cuboid = 40 cm³
Given that length of the cuboid (l) = 2 cm
Given that the width of the cuboid (w) = 4 cm
The volume of the cuboid is determined by
[tex]V = length X width X height[/tex]
40 = 2× 4× h
h = 5
The height of the cuboid = 5 cm

Nasser is following this recipe to make flapjacks.
Nasser uses 0.9 kg of oats.
How many flapjacks is Nasser making?
Recipe: Makes 10 flapjacks
120 g margarine
100 g sugar
150 mL syrup
225 g oats
40 g sultanas
Answer:
40 flapjacks
Step-by-step explanation:
Given the recipe :
Recipe: Makes 10 flapjacks
120 g margarine
100 g sugar
150 mL syrup
225 g oats
40 g sultanas
Given that all other ingredients are kept Constant.
225g of oats produces 10 flapjacks
0.9 kg of oat = 0.9 * 1000 = 900g oat
If :
225 g = 10 flapjacks
900 g = x
Cross multiply :
225x = 900 * 10
225x = 9000
x = 9000 / 225
x = 40
40 flapjacks
Write an expression for "h less than 13"
Answer:
13-h is h less than 13. this is how you answer this.
Hey there!
Sometimes “less than” means “>” ( a number smaller than the number that’s being compared to) or “subtraction”
So, therefore your answer should be
[h < 13] or [h - 13]
Good luck on your assignment and enjoy your day!

find the value of v
Answer:
v = 38
Step-by-step explanation:
A parallelogram is a quadrilateral in which both sides are the same. That means that 2v is equal to v + 38, and you can solve this. You would get that 2v = v + 38, which means that v = 38.

Answer:
1.a and 2.b.
Step-by-step explanation: let's say the area=2. if you multiply by 2, it gets bigger. if d<1, it's like dividing by a number, meaning that the area becomes smaller.
Answer:
1. a
2. b
Step-by-step explanation:
1. If d is greater than one (d>1), then that means that the shape will be dilated outward, or expanded because the number is larger than the unit of 1.
2. Multiplying the coordinates by a fraction that is less than one (0<d<1) makes the shape smaller, because fractions are smaller than the unit of 1.
