Scale Factor = 1 is it reduction or enlarge

Answers

I think it’s reduction

Answer:

The image remains the same.

Step-by-step explanation:

If the scale factor is one, then the image is not reduced or increased, it remains the same. This is because, if one multiplies the original image by the scale factor, then one will get the scaled answer. If one multiplies anything by 1, then they will get the number they multiplied by 1 (this is called the multiplicative identity property), hence the image remains the same.

In right angled triangle

Hypotenuse ² = perpendicular² + base²

Base = 22

Perpendicular = 27

Hypotenuse = x

[tex] \implies \: {x}^{2} = {27}^{2} + {22}^{2} [/tex]

Square of 27 and 22 are 729 and 484 respectively.

[tex] \implies \: x = 729 + 484[/tex]

[tex] \implies \: x {}^{2} = 1,213[/tex]

In this triangle, the product of sin B and tan C is
and the product of sin Cand tan B is

Answers

Answer:

[tex]\frac{c}{a}[/tex] and [tex]\frac{b}{a}[/tex]

Step-by-step explanation:

sinB = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{AC}{BC}[/tex] = [tex]\frac{b}{a}[/tex]

tanC = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{AB}{AC}[/tex] = [tex]\frac{c}{b}[/tex]

Thus

sinB tanC = [tex]\frac{b}{a}[/tex] × [tex]\frac{c}{b}[/tex] ( cancel b on numerator/ denominator )

                 = [tex]\frac{c}{a}[/tex]

---------------------------------------------------------------------------

sinC = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{AB}{BC}[/tex] = [tex]\frac{c}{a}[/tex]

tanB = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{AC}{AB}[/tex] = [tex]\frac{b}{c}[/tex]

Thus

sinC tanB = [tex]\frac{c}{a}[/tex] × [tex]\frac{b}{c}[/tex] ( cancel c on numerator/ denominator )

                 = [tex]\frac{b}{a}[/tex]

Subtract (4x2 - x + 6) from (3x2 + 5x - 8).
A. O 7x2 + 6x - 14
B. 7x2 + 4x - 2
C.x2 - 6x + 14
D. -x2 + 6x - 14

Answers

Answer:

[tex]\left(3x^2+5x-8\right)-\left(4x^2-x+6\right)=-x^2+6x-14[/tex]

Hence, option D is correct.          

Step-by-step explanation:

We have to subtract (4x² - x + 6) from (3x² + 5x - 8).

so

[tex]\left(3x^2+5x-8\right)-\left(4x^2-x+6\right)[/tex]

Remove parentheses: [tex]\left(a\right)=a[/tex]

[tex]=3x^2+5x-8-\left(4x^2-x+6\right)[/tex]

[tex]=3x^2+5x-8-4x^2+x-6[/tex]

Group like terms

[tex]=3x^2-4x^2+5x+x-8-6[/tex]

Add similar elements:  [tex]\:3x^2-4x^2=-x^2[/tex]

[tex]=-x^2+5x+x-8-6[/tex]

Add similar elements:  [tex]5x+x=6x[/tex]

[tex]=-x^2+6x-8-6[/tex]

Subtract the numbers: [tex]-8-6=-14[/tex]

[tex]=-x^2+6x-14[/tex]

Therefore,

[tex]\left(3x^2+5x-8\right)-\left(4x^2-x+6\right)=-x^2+6x-14[/tex]

Hence, option D is correct.
