Hello! And thank you for your question!

First move all the terms to one side:

<span>x^<span><span>2</span><span></span></span></span>−4x−9−29=<span>0
</span>
Then simplify x^2−4x−9−29:

<span><span><span>x<span><span>^2</span><span></span></span></span>−4x−38=0</span><span>
Then use the quadratic formula:

x = 4 + 2</span>√42 over 2 , 4 - 2√42 over 2

Finally simplify:

x = 2 + √42, 2 - √42

Final Answer:

x = 2 + √42, 2 - √42

What is the measure of KPN?

Debora [2.8K]

Answer:

angle KPN=95 degree

Step-by-step explanation:

angle KPN = angle JPO (because they are vertically opposite angles)

Now,

angle JPO+angle LOP=180 degree(being co interior angles)

angle JPO + 85 =180

angle JPO =180-85

angle JPO =95

since angle JPO is equal to KPN ,angle KPN is 95 degree

The URS construction company has submitted two bids, one to build a large hotel in London and the other to build a commercial o

topjm [15]

Answer: Our required probability is 0.55.

Step-by-step explanation:

Since we have given that

Probability that chance of winning the hotel bid = 40%

Probability that no chance of winning the hotel bid = 100-40=60%

Probability that chance of winning the office building bid = 25%

Probability that no chance of winning the office building bid = 100-25 = 75%

So, Probability that the company will win at least one contract is given by

$0.4\times 0.75+0.6\times 0.25+0.4\times 0.25\\\\=0.55$

Hence, our required probability is 0.55.

A recursive rule for an arithmetic sequence is a1=4;an=an−1−3 . What is the explicit rule for this sequence? Enter your answer i

Westkost [7]

Answer:

The explicit rule for the arithmetic sequence is given by:

$a_n = a_1+(n-1)d$ ......[1]

where,

$a_1$ is the first term

n is the number of terms and

d is the common difference for two consecutive terms.

As per the statement:

A recursive rule for an arithmetic sequence is:

$a_1 = 4$

$a_n = a_{n-1}-3$

The recursive formula for the arithmetic sequence is given by:

$a_n = a_{n-1}+d$

then;

On comparing we get;

d = -3

Substitute the given values in [1] we have;

$a_n = 4+(n-1)(-3)$

⇒ $a_n = 4 -3n+3 = 7-3n$

Therefore, the explicit rule for this sequence is, $a_n = 7 -3n$
