Answer:

8.14

Step-by-step explanation:

Ok.So to do this, you have to know the Pytharomean Theroem.If you do not know how,then that is totally ok.I will tell.So the theroem has a formula.

Down below is a image showing the variables.

Now the hypotenuse is c.And b and a are the legs.

So we can put evaluses in the formula(formula:a^2 + b^2 = c):

(6.0)^2 + (5.5)^2 = c^2

36 + 30.25=c^2

66.25=c^2

8.14 = c

So 8.14 is the anwser!

Given the two triangles are similar, what are the values of q and t? Round to the nearest hundredth.

Answers

Answer:

t = 7.5 cm , q= 7.5 cm.

Step-by-step explanation:

Given : Two similar triangle .

To find : what are the values of q and t ,Round to the nearest hundredth.

Solution : We have given Two similar triangle GHI and DEF.

Property of two similar triangle : The ratios of the lengths of their corresponding sides are equal.

Corresponding sides HI ≅ EF and GI≅DF. GH≅DE

HI = t , EF = 4.5 , GI = 12.5 , DF = q , Gh = 10 , DE = 6

$(t)/(4.5) = (10)/(6)$ .

On cross multiplication

t * 6 = 4.5 * 10.

t * 6 = 45 .

On dividing both sides by 6

t = 7.5 cm.

Now, for q

$(q)/(12.5) = (6)/(10)$ .

On cross multiplication

q * 10 = 12.5 * 6.

q * 10 = 75.0

On dividing both sides by 10

q= 7.5 cm.

Therefore, t = 7.5 cm , q= 7.5 cm.

Set up proportions. 6/10 = 4.5/t. Cross multiply 6t = 45. Divide both sides of the equation by 6 and get t = 7.5.
Next proportion is q/12.5 = 6/10. Cross multiply 10q = 750. Divide both sides of the equation by 10 and get q = 7,5.

Which value of x is a solution to this equation?2x^2 − 4x +16 = 0

x = 3

x=2

x = -2

Answers

Answer:

Solve the equation:

2x² − 4x + 16 = 0
x² - 2x + 8 = 0
x² - 2x + 1 + 7 = 0
(x - 1)² + 7 = 0
(x - 1)² = -7

There is no solution as the square of the number can't be negative

----------------------------

Note if the equation was 2x² - 4x - 16 = 0, the solution would be:

2x² - 4x - 16 = 0
x² - 2x - 8 = 0
x² - 2x + 1 = 9
(x - 1)² = 3²
x - 1 = ± 3
x = -2, x = 4

In this case x = -2 is the correct choice

Answer:

x = -2

Suppose y = 48 + 3(2n - 1) is an explicit representation of an arithmetic sequence for integer values n ≥ 1. Find the xth partial sum of the series, as a quadratic function, where x represents the term number.

Answers

Answer: 3x2 + 51x

Step-by-step explanation:

$a_n=48+3(2n-1)$

The formula of the sum of the arithmetic sequence:
$S_n=(a_1+a__n)/(2)\cdot n$
calculate:
$a_1=48+3(2\cdot1-1)=48+3=51$
substitute
$S_n=(51+48+3(2n-1))/(2)\cdot n=(99+6n-3)/(2)\cdot n=(96+6n)/(2)\cdot n=3n^2+48n$
Your answer is:
$\boxed{f(x)=3x^2+48x}$
