I Really Need Help With This Question :)

Answers

Answer 1

Answer:

here you go.

Step-by-step explanation:

The diagonal is the hypotenuse of a rectangular triangle.

So:

d2=l2+w2 

132=169=(x+7)2+x2=x2+14x+49+x2→

2x2+14x−120=0→x2+7x−60=0

A simple quadratic equation resolving into:

(x+12)(x−5)=0→x=−12orx=5

Only the positive solution is useable so:

w=5andl=12

What is the value of 2/3(x-6)-Y when x = 9 and y = 5/6?

Answers

Replace x and y with the given values:

2/3(9-6) - 5/6

Simplify:

2/3(3) - 5/6

Multiply:

2 - 5/6

Subtract:

1 1/6

Answer 1 and 1/6

The required simplified value of 2/3(x-6)-Y when x = 9 and y = 5/6 is 7/6.

To find the value, substitute the given values of x and y into the expression:

2/3(x - 6) - y

= 2/3(9 - 6) - 5/6

= 2/3(3) - 5/6

= 2 - 5/6

To subtract fractions, you need a common denominator:

= 12/6 - 5/6

= 7/6

Therefore, the simplified value of 2/3(x-6)-Y when x = 9 and y = 5/6 is 7/6.

Paul is riding his bike 48 miles to the beach. His average rate of speed is 13.8 miles per hour. Paul stopped for a snack after 3 hours. How many miles does he have to go after his snack? Round your answer to the nearest tenth if necessary.
Paul has 3.5 miles to go after his snack.
Paul has 6.6 miles to go after his snack.
Paul has 34.2 miles to go after his snack.
Paul has 45.0 miles to go after his snack.

Answers

Answer:

Paul has 6.6 miles to go after his snack.

Step-by-step explanation:

Speed is the rate of moving. The speed can be calculated by dividing the distance traveled by the amount of time it took.

speed= distance/time  , v=d/t

So,from Paul's average speed we can calculate how much distance he has passed after 3 hours.

distance_3h=v*t=13.8 miles per hour * 3 hours

distance_3h=41.4 miles

There are total 48 miles to the beach, so Paul have to go 48miles-distance_3h after his snack, which gives:

48-41.4=6.6 miles

h: the horizontal <----------->

Step-by-step explanation:

shape BCD is an isosceles triangle meaning the base angles will be the same.

CA is a straight line meaning that it is 180

the sum of angles in a triangle always is 180

so

180-36= 144

to find x you need to half 144 as it is the sum of the base angles of the isosceles triangle.

144/2= 72

x=72

the angle just below y is also 72.

as CA is a straight line,

180-72= 108 giving you the answer for y

y= 108

so to make the answer clear

x= 72

y= 108

Any cosine function can be written as a sine function. y = A sin(Bx) and y = A cos(Bx). The number, A, in front of sine or cosine changes the height of the graph. The value A (in front of sin or cos) affects the amplitude (height).

Step-by-step explanation:

so levt's label the video games as "P"

if 6P=207.54$

1P= X

1P × 207.54$ = 6P × X

1P × 207.54$ = 6P × X => P eliminates P on the right side

6P 6P. => 6P eliminates 6P on the left side

207.54$ = X

6

X = 34.59$

Step-by-step explanation:

Let the cost of 1 video game = x

6 video games = $207.54

1 video game = x........cross multiply

6x = 207. 54............ divide both sides by 6

x = 34.59

therefore, 1 video game costs $34.59

Write a possible polynomial function in factored form with roots 0, -2, and 7. Group of answer choices
f(x)=(x+1)(x+2)(x−7)
f(x)=x(x+2)(x−7)
f(x)=x(x−2)(x+7)
f(x)=(x+2)(x−7)

Answers

Answer:

2nd option

Step-by-step explanation:

Given x = a is a root of a polynomial function then (x - a) is a factor

Given roots are x = 0, x = - 2, x = 7 , then corresponding factors are

(x - 0) , (x - (- 2) ) , (x - 7) , that is

x , (x + 2) , (x - 7)

The polynomial function f(x) is then the product of the factors, so

f(x) = x(x + 2)(x - 7)

Step-by-step explanation:

Use Pythagorean theorem,

base² + altitude² = hypotenuse²

7² + altitude²  = 25²

      altitude²  = 25² - 7²

                       = 625 - 49

                       = 576

altitude = √576

altitude = 24

Answers

The system of inequalities models correctly the number of cookies is c + b ≥ 125 and 8c + 12b ≤ 2000

Let c represent the number of cookies and let b represent the number of brownies.

Since Genie want to make more than 125 cookies and brownies altogether, hence this is given by:

c + b ≥ 125   (1)

Also, Genie has a total of 2,000 grams of flour, hence:

8c + 12b ≤ 2000  (2)

Therefore the system of inequalities models correctly the number of cookies is c + b ≥ 125 and 8c + 12b ≤ 2000
