Answer:

Step-by-step explanation:

Hello,

Let 's notice that

x^2-25=x^2-5^2=(x-5)(x+5) \ \ and \\\\x^2-3x-10=(x-5)(x+2) \ \text{as sum of the zeroes is 3 and the product is -10}

So the least common denominator is

(x-5)(x+5)(x+2)

hope this helps

Because bernard has some health issues, he must pay 15% more for life insurance. about how much more annually will a $115,000 10
Sergeu [11.5K]

The amount more annually a $115,000 10-year term insurance at age 35 cost Bernard than someone of the same age without health issues is $24.

<h3>What are insurance premiums?</h3>

The insurance premium is paid as a cost to cover a possible loss that is unseen.

The annual premium rate as a percentage of the value insured a person at age 35 has to pay is 0.14%.

From the given information, we have that the amount a 35-year-old without health issues will pay per $1,000 is $1.40

The amount to be paid for $115,000 is 115 × $1.4 = $161

The amount Bernard pays = 15% more

= 1.15 × $161

= $185.15

Therefore,

The amount more Bernard has to pay = $185.15 - $161

= $24.15 ≈ $24

Trigonometry lesson. Find X and Y
noname [10]

Answer:

12 =x

20.78460969=y

Step-by-step explanation:

sin theta = opposite side / hypotenuse

sin 60 = y /24

Multiply each side by 24

24 sin 60 = y/24*24

24 sin 60 =y

20.78460969=y

cos theta = adjacent side / hypotenuse

cos 60 = x /24

Multiply each side by 24

24*cos 60 = x/24*24

24 cos 60=x

12 =x

Please help me is this statement true or false 3(36 - 11) = 45?
viva [34]
Hi there! The answer is FALSE

To find the answer we need to work out the parenthesis.
3(36 - 11) =
3 \times 36 - 3 \times 11  =
108 - 33 =
75

75 does not equal 45 and therefore the statement is false.

aka
1 times 1^2=1
2 times 2^2=8
3 times 3^2=27
x times x^2=x^3

the rule is y=x^3
