the sequence?

We are told that f(1) = -1.5, and that f(n+1) = -2f(n).
Then: f(2) = -2f(1) = -2(-1.5) = +3 (answer)

When two fractions are between 0 ½, how do you know which fraction is greater? Explain

Serga [27]

0 1/4 and 0 These are both lower fractions because 0 plus a half..and 0 and 1/4. Sorry I'm not great at explaining

CAN SOME ONE HELP ME WITH THIS HURRY PLEASE

Nina [5.8K]

7) x= men
x+6= women

x + (x+6)= 30
2x + 6= 30
2x= 24
x= 12
x+6= 18

8) x= first integer
x+1= second integer
x+2= third integer

x + (x+1) + (x+2)= 153
3x + 3= 153
3x= 150
x= 50

Second integer
= x+1
= x+50
= 51

9) x= first integer
x+2= second integer
x+4= third integer

x + (x+2) + (x+4)= 54
3x + 6= 54
3x= 48
x= 16

x + (x+2)= 34
16 + 16 + 2= 34
34=34

10) rate= 356 km/hr
distance= 1424 km

Distance= rate * time
D= rt
1424= 356 * t
divide both sides by 356
4 hrs= t

ANSWERS:
7) 18 (B - second choice down)
8) 51 (B - second choice down)
9) 16 (D - fourth choice down)
10) 4 (B- second choice down)

Hope this helps! :)

2 - ( - 8 ) + ( - 3 ) =

solmaris [256]

Hey!

First, let's write the problem.
$2-\left(-8\right)+\left(-3\right)$
We know that, $-\left(-8\right)=+8$ , so let's apply that
$=2+8+\left(-3\right)$
We have to add, $2+8=10$
$=10+\left(-3\right)$
We know that $+\left(-3\right)=-3$ , so let's apply that.
$=10-3$
Subtract. $10-3=7$
$=7$

Our final answer would be 7!

Thanks!

Find ST if S(-3, 10) and T(-2, 3)

FrozenT [24]

We have the following points and their coordinates:

$\begin{gathered} S(-3,10), \\ T(-2,3). \end{gathered}$

We must compute the distance ST between them.

The distance ST between the two points is given by:

$ST=\sqrt[]{(x_S-x_T)^2+(y_S-y_T)^2_{}},$

where (xS,yS) are the coordinates of the point S and (xT,yT) are the coordinates of the point T.

Replacing the coordinates of the points in the formula above, we find that:

$\begin{gathered} ST=\sqrt[]{(-3_{}-(-2)_{})^2+(10_{}-3_{})^2_{}}, \\ ST=\sqrt[]{1^2+7^2}, \\ ST=\sqrt[]{50}\text{.} \end{gathered}$

Answer: ST = √50

Pls help me with this! (Links=report)

Answer:

XZ=12 in

Step-by-step explanation:

area of a rhombus is A=pq/2

where p=WY=15.5 and A=93 and q=XZ

93=15.5(XZ)/2

93(2)=15.5(XZ)

186/15.5=XZ

XZ=12 in
