Answer: 25

Step-by-step explanation:

To figure out the mystery number, the biggest clue we have is the fact that the number is a double digit and the 2 integers add up to 7. We can list out the possible ways to get a sum of 7. Then we can see which is the mystery number.

0+7

1+6

2+5

3+4

With these pairs, we can automatically eliminate 0+7 because 70 is greater than 30. We can also eliminate 3+4 because 34 is even, not odd. When you flip it to 4+3, it is odd, but it is greater than 30. We can also eliminate 1+6 because 16 is even and 61 is greater than 30. Our answer is 25. 2+5=7 and 25 is odd that is less than 30.

Answer:

Tan 45=√2/n

n=√2

again

sin 45=√2/m

m=2

answer: m=2,n=√2

2.

sin 45=x/3

x=3/√2=3√2/2

y=3√2/2

ans:x=3√2/2,y=3√2/3

3.

sin 45=a/4

a=4/√2

b=4/√2

ans:a=4/√2,b=4/√2

b=4 base sides of isosceles triangle

sin 45=4/a

a=4√2

ans:a=4√2 and b=4

Answer:

Rx)=1/3x^2

Step-by-step explanation:

A horizontal stretch is simply making the parabola of the parent function wider, it's kind of like changing the slope of a line to make it less steep.

In the graph, the red line is the parent function and the blue line is the horizontally stretched function. See how the blue line appears to be stretched (horizontally).

How would you explain to someone the rules of a horizontal translation where we are subtracting from the inputs(within the paren

chubhunter [2.5K]

Answer:

Ok, we know that we can write a horizontal translation as:

y' = f(x - A)

where if A is positive, this moves the graph of f(x) A units to the right.

Why is this?

Ok, let's compare:

y = f(x)

and

y' = f(x - A)

in y, when x = 0 we have f(0).

While to have this same point in y', we need to evaluate in x = A.

f(A - A) = f(0).

Then the value f(0) is now at x = A, this means that the point moved A units to the right.

And you can do this for all the values, so you will find that the entire graph of f(x) has ben moved A units to the right.

Which expression shows how to multiply 5x381 by using place value and exxpanded form?

Dovator [93]

1. We have the given number = 5 x 381
Let’s show how to multiply this given equation using its expanded form and place value
=> 5 x 381
since we’re multiplying, we will start with the ones value which is 1
=> 5 x 1 = 5
Second is on the tens value
=> 5 x 80 = 400
Third is the hundreds value
=> 5 x 300 = 1 500
Now, we already have the answer to each values. Add
=> 1 500 + 400 + 5
=> 1 905
