Answer 1

Answer:

D. -3z+2

Step-by-step explanation:

Steps:

Remove parentheses: (a) = a

= 5z+9-(8z+7)

....

Simplify

5z+9-8z-7: -3z+2

Answer 2

Answer:

-3z +2

Step-by-step explanation:

A expression in terms of z is given to us and we need to simplify out the given expression . The give an expression to us is ,

[tex]\implies (5z + 9 ) - ( 8z + 7 )[/tex]

Recall that , + × - = - . We have ,

[tex]\implies 5z + 9 - 8z - 7 [/tex]

Combining the like terms and simplifying ,

[tex]\implies 5z - 8z - 7 +9 \\\\\implies \underline{\underline{ -3z +2 }}[/tex]

Hence the last option is correct .

A. work backwards
B. use a formula
C. make a table, chart or list
D. make a model or diagram

Answers

Answer:

The correct option is;

B. Use a formula

Step-by-step explanation:

Given that Jim and Lillian have the dimensions of the wall they want to paint, therefore, in order to know how much paint they need to buy, they should proceed as follows;

1) Determine the quantity of paint required to paint a unit area of the wall, and record the quantity UA

2) Calculate the area, A, of the wall they want to paint, which is 15 ft. × 9 ft. = 135 ft.²

3) The amount of paint needed, AmP is therefore given by the following formula

AmP = A × AU = 135 × AU

Answer:i dont know

find the constant rate of change​

Answers

Answer:

- 2 ft/ s

Step-by-step explanation:

The rate of change is the slope m of the line.

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (0, 80) and (x₂, y₂ ) = (40, 0) ← 2 points on the line

m = [tex]\frac{0-80}{40-0}[/tex] = [tex]\frac{-80}{40}[/tex] = - 2

Rate of change is - 2 ft/ s

Given:

A right angled triangle.

To find:

The value of x.

Solution:

We have,

Base = x

Hypotenuse = [tex]\sqrt{5}[/tex]

In a right angle triangle,

[tex]\cos \theta = \dfrac{Base}{Hypotenuse}[/tex]

For the given triangle,

[tex]\cos 45^\circ= \dfrac{x}{\sqrt{5}}[/tex]

[tex]\dfrac{1}{\sqrt{2}}= \dfrac{x}{\sqrt{5}}[/tex]

Multiply both sides by [tex]\sqrt{5}[/tex].

[tex]\dfrac{\sqrt{5}}{\sqrt{2}}= x[/tex]

[tex]\dfrac{\sqrt{5}}{\sqrt{2}}\times \dfrac{\sqrt{2}}{\sqrt{2}}= x[/tex]

[tex]\dfrac{\sqrt{10}}{2}= x[/tex]

Therefore, the required value of x is [tex]\dfrac{\sqrt{10}}{2}[/tex].

Which polynomial can be factored using the binomial theorem?

100x2 + 70x + 49
100x2 + 210x + 49
1,000x3 – 2,100x2 + 1,470x – 343
1,000x3 – 2,800x2 + 1,960x – 343

Answers

Answer:C

Step-by-step explanation:

The polynomial can be factored using the binomial theorem is

1,000x³  – 2,100x² + 1,470x – 343.

What is Binomial Theorem?

Assertion that the sum of the nth power of the product of two positive integers a and b may be written as the sum of the n + 1 terms of the form for any positive integer n.

If a and b are real numbers and n is a positive integer, then

[tex](a + b)^n =^nC_0 a_n + ^nC_1 a_{n-1} b_1 + ^nC_2 a_{n-2} b_2 + ... 1.[/tex]

Given:

Using Binomial we can write

(a+ b)³ = a³ + b³ + 3a²b + 3ab²

and, (a+ b)² = a² + 2ab + b²

So, 100x²+ 70x + 49 and 100x² + 210x + 49 cannot be factors using Binomial Theorem because the correct expansion would be

(10x+ 7)² = 100x² + 140x + 49

and, 1,000x³  – 2,100x² + 1,470x – 343 can be factored using Binomial theorem.

As, (10x - 7)³ = 1000x³ -2100x² + 1470x - 343.

Cancer Read the passage and answer the questions that follows :(1) We all want to succeed. Whether its in losing weight learning the guitar,speed reading, or starting our own business. For those of us who have triedand failed, success seems elusive. Why is it one person succeeds where anotherpersonal fails? First and foremost, I believe it is in their mindset. But secondly,I believe that successful people have developed certain habits, either naturallyor through research that the rest of us havent stumbled upon yet.(2) What is important to you? Finding your core values may seem a bit off-topicwhen it comes to success, but creating goals that are in line with your valuesis key to creating intrinsic motivation. Sit and reflect on what you value most.Pick a handful of things and actually write them down. Remind yourself ofyour values every day, and reflect on whether you are honoring those valuesthrough your work.(3) Choose one goal to start. Something large enough that will give you a sense ofaccomplishment, while aligning well with your core values. Focus is key here.The more focused you are on one goal, the higher chance you have of success.Set a date for success. Identify when your hope to achieve your goal. Keepit realistic, while not giving yourself too much time. By setting a time limit, youare making the process more real. Believe fully in your ability to achieve yourgoal. Visualize yourself having completed your goal in the exact time-frameyou have chosen, although finishing early is also acceptable. You dont needto consider the failures that will happen along the way. Success is inevitable.Others may think you will fail, dont let yourself be one of them!(4) Set up negative consequences for missing the deadline. Necessity is the motherof all invention. If you can manage to keep yourself intrinsically motivated,thats great. If not, this will help kick you into gear and keep your eye on theprize. Prioritize the tasks you have in front of you. Dont always do the mosturgent thing first. Pick the task thats the most important. Sometimes theseoverlap, which is nice. By always accomplishing whats most important, youare making clear progress toward your goal.(5) Push yourself. Go out of your comfort zone. This is the best way to learn, andthe best way to make progress quickly. If youre looking for new ideas, beingrisk averse will not help. This takes a lot of self-awareness. Try and beconscious of when you are holding yourself back out of fear. Push yourself tobe courageous, and take that next step. Failure is inevitable when you takerisks, which is what youll be doing if you want to succeed. By its very definition,the desire to succeed at something means you are risking failure. Many peopletend to give up far too early. Use failure. Treat it as a good thing, and marchon!(6) Take time every day to sit quietly and reflect on your values, goals, and progressmade so far. Where have you excelled, and where can you do better. Iseverything you are doing still lining up with your core values? Always look forways to improve. Never stop learning. Know what everyone else is doing,and what everyone else has done, and how they did it. Search wide forknowledge that might help you, and any inspiration that may do the same.Never think you have nothing to learn from others.(a) On the basis of your reading of the above passage, make notes on itsusing recognizable abbreviations (Min. 4) wherever necessary.
