15(x + 3)2<br> Box the exponent (s) <br> please help

sertanlavr [38]

Answer:

"2" is the exponent

Step-by-step explanation:

There is no exponent in your expression.

When the expression is typeset, the superscript text is considered to be an exponent:

$15(x+3){\boxed{^2}}$

When the expression is written in plain text, the exponent is indicated by a caret (^):

$\textsf{15(x+3)\^\ \!\!\boxed{\textsf{2}}}$

The circumference of a circle is 15.2mm.

bulgar [2K]

Answer:

circumference of circle (c)=15.2mm

length of radius (r)=?

we know,

c= 2×pi×r=2×3.14×r

or,15.2/6.28=r

or,2.4=r

2.4mm=r

DedPeter [7]

Answer: 2535

Step-by-step explanation:

use order of operations (parenthesis, exponents, multiplication/division, addition/subtraction)

first ill handle the two innermost parenthesis

(4 + 3(2 - 8))

(4 + 3(-6))

(4 - 18)

-14

now lets move on to the next parenthesis

( 3 - 5^2(-14))

(3 - 25( - 14)

( 3 + 350)

353

now onto the last part of the problem

8^2 + 7 (353)

64 + 2471

2535 :))

Find a formula for the general term an of the sequence, assuming that the pattern of the first few terms continues. (assume that

Lilit [14]

Your sequence
-8, 16/3, -32/9, 64/27
is a geometric sequence with first term -8 and common ratio
(16/3)/(-8) = (-32/9)/(16/3) = -2/3

The general term an of a geometric sequence with first term a1 and ratio r is given by
an = a1·r^(n-1)
For your sequence, this is
an = -8·(-2/3)^(n-1)

Suppose the weekly amount of money spent on maintenance and repairs by a company is NOT approximately normally distributed. Howe

UNO [17]

Answer:

Probability = 0.00621

Step-by-step explanation:

We are given;

Population mean; μ = 400

Population standard deviation; σ = 20

Raw score; x¯ = 450

the probability that the actual costs will exceed the budgeted amount will be the p-value.

Thus, let's first find the z-score after which we will find the p-value.

z = (x¯ - μ)/σ

z = (450 - 400)/20

z = 50/20

z = 2.5

From online p-value from z-score calculator attached, using z = 2.5; one tailed hypothesis; significance level of 0.05, we have;

P-value = 0.00621
