Answer:

a) 47.7%

b) 87.2%

Step-by-step explanation:

Find the ratio of interest, and convert it to a percentage.

(messy right-handed writers)/(right-handed writers)

= 31/65 = 31/65 × 100% ≈ 47.7%

(neat right-handed writers)/(neat writers)

= 34/39 = 34/39 × 100% ≈ 87.2%

The rhombus, m<1 = 168. what are m<2 and m<3?

Ket [755]

Answer:

∠2 = 168°

∠3 = 6°

Step-by-step explanation:

Opposite angles of a rhombus are congruent, so ∠2≅∠1 = 168°.

∠3 is the base angle of the isosceles triangle with an apex angle of 168°. Hence it will be (180° -168°)/2 = 6°.

Identify the parent function that can be used to graph the function f(x)= -9(x+5)2

olga nikolaevna [1]

Answer:

The parent function that can be used to graph $f(x)=-9(x+5)^2$ is:

$f(x)=x^2$

Step-by-step explanation:

We are asked to find the parent function that can be used to graph the function f(x) which is given as:

$f(x)=-9(x+5)^2$

We know that from the given options the parent function that best represents the relationship or that can be used to graph the function f(x) is:

$f(x)=x^2$

since the function $f(x)=-9(x+5)^2$ is just a transformation of the parent function the transformation that is applied is a combination of a dilation with a scale factor '-9' and a translation '-5' units to the left and a reflection along 'x' axis.

Hence, the parent function is:

$f(x)=x^2$
