Which of the following describe an angle with a vertex at A?
Check all that apply.
O A. _BAC
B. CAB
OC. ZACB
OD. ABC

Answer:

Just leave it how it is, you don't have to do anything with the negative symbol.

We are given that ,

[tex]{:\implies \quad \sf \dfrac{12+\sqrt{128}}{1-\sqrt{2}}=a+b\sqrt{2}}[/tex]

Consider LHS;

[tex]{:\implies \quad \sf \dfrac{12+\sqrt{128}}{1-\sqrt{2}}}[/tex]

Can be further written as ;

[tex]{:\implies \quad \sf \dfrac{12+8\sqrt{2}}{1-\sqrt{2}}}[/tex]

Rationalizing the denominator we have ;

[tex]{:\implies \quad \sf \dfrac{12+8\sqrt{2}}{1-\sqrt{2}}\times \dfrac{1+\sqrt{2}}{1+\sqrt{2}}}[/tex]

[tex]{:\implies \quad \sf \dfrac{(12+8\sqrt{2})(1+\sqrt{2})}{(1-\sqrt{2})(1+\sqrt{2})}}[/tex]

[tex]{:\implies \quad \sf \dfrac{12(1+\sqrt{2})+8\sqrt{2}(1+\sqrt{2})}{1-2}}[/tex]

[tex]{:\implies \quad \sf \dfrac{12+12\sqrt{2}+8\sqrt{2}+16}{-1}}[/tex]

[tex]{:\implies \quad \sf \dfrac{28+20\sqrt{2}}{-1}}[/tex]

[tex]{:\implies \quad \sf -28-20\sqrt{2}}[/tex]

Hence, we can conclude that ;

Answer:

[tex]\dfrac{\pi }{2}[/tex]

Step-by-step explanation:

The period of the function is from one peak to the next (or from one trough to the next).

[tex]\sf \implies period=\dfrac{\pi }{2}[/tex]

**see attached for the measurement of the period for this function**

Answer:

15•4 mm

Step-by-step explanation:

using sine rule

a÷ sinA=c ÷sinC

15•4÷sin90=0•5÷sinC

sinC =0•5 × sin90 ÷ 15•4

C =1•9°

A+B+C= 180

90+B+1•9=180

B= 88•2°

b÷sinB = a÷sinA

b÷sin88•2= 15•4÷sin90

b=sin88•2 ×15•4 ÷sin90

b =15•39

to 1 dp

b =15•4 mm

Integer, rational number, and real number

Step-by-step explanation:

Integer is a number that can be either positive or negative, but can't be a fraction or irrational number such as pi. It's also a subset of rational numbers, which is a subset of real numbers.

Answer:

y= [tex]\frac{72}{5}[/tex] or 14.4

Step-by-step explanation:

[tex]\frac{5}{6}y = 12\\[/tex]

Multiply both sides by 6/5, the reciprocal of 5/6.

[tex]y = 12 * (\frac{6}{5} )[/tex]

Express 12 x (6/5) as a single fraction.

[tex]y = \frac{12 * 6}{5}[/tex]

Multiply 12 and 6 to get 72.

[tex]y = \frac{72}{5}[/tex]

Answer: C or 6/5

Step-by-step explanation: the question is 4/5 plus 2/5 so 6/5

Answer:

Perimeter = 10

Step-by-step explanation:

Horizontally 3 units; vertically 2 units.

If h is horizontal measure, and v is vertical measure, then perimeter is 2(h+v) and area is hv.

[4] The Perimeter of the rectangle is how many units?

Perimeter formula ; 2(h+v)

2(3+2) = 10

Answer:

The 25th term is 97

Step-by-step explanation:

The explicit rule is f(n)=4n-3

Let f(n) = 97

97 = 4n-3

Add 3 to each side

97+3 = 4n-3+3

100 = 4n

Divide by 4

100/4 = 4n/4

25 = n

Answer: John ran 10 miles through Monday and Wednesday.

Step-by-step explanation: He ran for miles on 4 but 4 more than Monday and he ran 3 miles on Monday, so you add 4 + 3 which = 7 then you add 3 to 7 because he ran 3 miles on Monday then you get 10.

Since the dilation is centered at the origin, you can multiply each of the coordinates by the scale factor. This means the image is A'(-6, -6)

Answer: 25 feet

Step-by-step explanation:

If you place a 37 foot ladder against the top of a 12 food building, since 37 is greater than 12 the ladder will keep going past the building.

37-12=25

the ladder will be 25 feet from the bottom of the building

Hey there!

Step 1: Calculate percentage

Since 30% of the marbles are green

=> 80 × 30/100

=> 8 × 30/10

=> 240/10

=> 24

So, 24 of the marbles are green

Step 2: Substract 24 from 80

=> 80 - 24

=> 56

Therefore, 56 marbles are not green

Answer:

16................

Step-by-step explanation:

Above

Answer:

The answer is 16.

Step-by-step explanation:

Negatives can be tricky, but once you get the hang of it, it will be much easier! The rule to remember here is:

"Anything 'minus a negative' just means plus, because the negatives cancel each other out."

a. For example, 4 -(-1) is the same thing as 4+1, which equals 5.

b. In this problem, 12-(-4) is the same thing as 12+4, which equals 16.

I hope this helps! Feel free to give me Brainliest if you feel this helped. :)

Answer:

A

Step-by-step explanation:

The slope is 2/5. Plug in the points and slope into the slope- intercept form y-y1=m(x-x1).

It would be...

y-4=2/5(x+2)
