Answer:

159

Step-by-step explanation:

You need to remember BIDMAS

B - brackets

I - indecieas 4 to the power of 5 for example

D - divide

M - multiply

A - add

S - subtract

Its the order in which you have to do everything.

So first do the brackets

3 + 5 = 8 and then do the indecies so 8 squared = 64

then do 10 cubed which is 100

for the moment we have 100 + 64 - 5

so the answer is 159

Hope this helps :D

Answer:

$\frac{2}{4} inch$

Step-by-step explanation:

Step 1

List the length of the wingspan of the five butterflies

$\frac{1}{4}, \frac{1}{4}, 1, \frac{2}{4}, \frac{3}{4}$

Step 2:

The two butterflies with the shortest wingspan has a wing length of $\frac{1}{4}$ inches each.

Step 3:

Total length of the wingspan of the two butterflies with the shortest wingspan

= $=\frac{1}{4} +\frac{1}{4} \\
 = \frac{2}{4}$

Final answer:

= $\frac{2}{4} inch$

What are the vertex and xintercepts of the graph of the function below?<br> y=(x + 4)(x-2)

erik [133]

Yo sup??

y=(x+4)(x-2)

to find the x intercept put y=0

0=(x+4)(x-2)

so either x=-4 or x=2

Therefore the graph intersects the x axis at -4 and 2

Lenght of x intercept=|-4-2|=6 units

y=(x+4)(x-2)

=x^2+2x-8

This is an upward opening parabola

To find the coordinates of the vertex we can apply the formula

(-b/2a,-D/4a)

b=2

a=1

D=b^2-4ac

=4-4*1*(-8)

=4+32=36

Vertex=(-2/2*1,-36/4*1)

=(-1,-9)

Hope this helps.

For some integer n, the first, the third and the fifth terms of an arithmetic sequence are respectively 3n, 5n – 6, and 11n + 8.

Mazyrski [523]

Answer:

a₄=8n+1= -39.

Step-by-step explanation:

1) if a₁=3n; a₃=5n-6 and a₅=11n+8, then it is possible to calculate the difference according to 0.5(a₅-a₃)=0.5(a₃-a₁). Then

2) 0.5(11n+8-5n+6)=0.5(5n-6-3n); ⇔ 6n+14=2n-6; ⇔ n= -5.

3) if n=-5, then the 4th term is:

$a_4=\frac{a_5+a_3}{2}; \ = > \ a_4=\frac{11n+8+5n-6}{2}=8n+1;$

or a₄=-39.
