eduard

Let's factor x^2−22x+121

The middle number is -22 and the last number is 121. Factoring means we want something like

(x+_)(x+_)

Which numbers go in the blanks? We need two numbers that...

Add together to get -22

Multiply together to get 121

Can you think of the two numbers?

Try -11 and -11:

-11+-11 = -22

-11*-11 = 121

Fill in the blanks in

(x+_)(x+_)

with -11 and -11 to get...

(x-11)(x-11)


Answer: (x-11)(x-11)


Hope this helps!!!

2. The bottom of a ramp is placed 15 feet from the edge of a stage
Firdavs [7]

Answer:

The slope of the ramp is 1.

Step-by-step explanation:

See the diagram attached.

Here, AC  = 15 ft. and ED = 5 ft. while AE = 10 ft.

Then, EC = (15 - 10) = 5 ft.

Now, considering the right triangle Δ EDC, if \theta is the inclination of the ramp, then \tan \theta = \frac{ED}{EC} = \frac{5}{5} = 1

Hence, \theta = 45 ^{\circ}

Therefore, the slope of the ramp is 1. (Answer)

Design an instructional activity that could help learners recognise that decimal
sp2606 [1]

Fraction refers to a part of a whole; e.g when cup is not completely filled, it covers only a part of the cup

<h3>What is fraction?</h3>

The term fraction refers to a part of a whole. To design an instructional activity that  could help learners recognize that decimal fractions can be applied across environmental situations, we could look at certain things in the house.

For instance, when cup is not completely filled, it contains water that covers only an fraction of the cup. Also, we could boil a part and not a whole cup of rice. These are all examples of fractions.

Write -2i + (9 - 3i) - (6 - 10i) as a complex number in standard form. 3 - 5i 3 + 5i 3 + 16i 12 - 16i
Ierofanga [76]

Answer:

3 + 5i

Step-by-step explanation:

Given

- 2i + (9 - 3i) - (6 - 10i) ← distribute parenthesis

= - 2i + 9 - 3i - 6 + 10i ← collect like terms

= 3 + 5i
