Answer:

A and D

Step-by-step explanation:

A.) plug in 2 first then 4

2^2= 4 and 4^2= 16 so it applies

B.) does NOT apply bc 2+6=8 and not f(2)=4 and also does not equal to 16

4+6=10

C.) does NOT apply bc 4(2)+2=10 and not to 4 and also does not equal to 16; 4(4)+2=18

D.) does apply 2^2=4 and 2^4=16

1. 8/9 ÷ 4/9 is done by inverting the divisor (4/9) and then multiplying:

(8/9)(9/4) = 8/4 = 2 (answer)

2. 1/3 ÷ 6 is done similarly: (1/3)(1/6) = 1/18 (answer)

3. 4 ÷ 1/5 = 4 * 5 = 20 (answer)

4. 7 1/2 ÷ 1/4 = (15/2)(4/1) = 30 (answer)

PART A: Mrs. konsdorf claims that angle R is a right angle.Is Mrs. konsdorf correct? explain your reasoning PART B: if T is trab

Anna007 [38]

Answer:

Part A: Angle R is not a right angle.

Part B; Angle GRT' is a right angle.

Step-by-step explanation:

Part A:

From the given figure it is noticed that the vertices of the triangle are G(-6,5), R(-3,1) and T(2,6).

Slope formula

$m=\frac{y_2-y_1}{x_2-x_1}$

The product of slopes of two perpendicular lines is -1.

Slope of GR is

$\text{Slope of GR}=\frac{1-5}{-3-(-6)}=\frac{-4}{3}$

Slope of RT is

$\text{Slope of RT}=\frac{6-1}{2-(-3)}=\frac{5}{5}=1$

Product of slopes of GR and RT is

$\frac{-4}{3}\times 1=\frac{-4}{3}\neq -1$

Therefore lines GR and RT are not perpendicular to each other and angle R is not a right angle.

Part B:

If vertex T translated by rule

$(x,y)\rightarrow(x-1,y-2)$

Then the coordinates of T' are

$(2,6)\rightarrow(2-1,6-2)$

$(2,6)\rightarrow(1,4)$

Slope of RT' is

$\text{Slope of RT'}=\frac{4-1}{1-(-3)}=\frac{3}{4}$

Product of slopes of GR and RT' is

$\frac{-4}{3}\times \frac{3}{4}=-1$

Since the product of slopes is -1, therefore the lines GR and RT' are perpendicular to each other and angle GRT' is a right angle.

A recipe for 24 cookies calls for 4 tablespoons of sugar. If you make 40 cookies and use 5 tablespoons, will the cookies taste t

uranmaximum [27]

Answer:

Step-by-step explanation:

No, because they wouldn't contain the same amount of sugar per cookie

for the first recipe - 24 cookies with 6 tablespoons

thats 6/24 so 0.25 tablespoons of sugar per cookie

for the second recipe - 36 cookies with 10 tablespoons

thats 10/36 so 0.276 tablespoons per cookie

the cookies in the second recipe would be slightly sweeter than the cookies in the first
