Answer:

[tex]m<49/12[/tex]

Step-by-step explanation:

we are given

[tex]y = 3x^2+7x+m[/tex]

To find x-intercept means we have to find zeros

and for finding zeros , we will use quadratic formula

and we have it has two x-intercepts  

so, it's discriminant must be greater than 0  

so, we will find discriminant

[tex]D = \sqrt{b^2-4ac}[/tex]

now, we can compare with

[tex]y=ax^2+bx+c\\y=3x^2+7x+m[/tex]

and then we can find a , b and c

a = 3, b = 7, c = m

now, we can find D

[tex]D = \sqrt{7^2-4*3*m} \\D=\sqrt{49-12m}[/tex]

It has two x-intercepts

so,

[tex]D = \sqrt{49-12m}>0[/tex]

now, we can solve for m

[tex]49-12m>0\\12m<49\\m<49/12[/tex]

What is transformation?

The transformation can be defined as the introduction of a new set of mathematical coordinates that are declared to be different functions of the original coordinates.

The translation can be found by observing any one coordinate of the image and the preimage.

Hence, The rule that can describe the translation of the black triangle into the blue triangle is T<-3, -4>(x,y).

b. If the total distance was less than 30 km, form an inequality in , and
then solve it!

Answers

Answer:

Step-by-step explanation:

The question is incomplete. Here is the complete question;

A kid traveled a distance of 9 km by bike, and then walked a distance of x km.

a.Find the total distance traveled in terms of  x

b. If the total distance was less than 30 km, form an inequality in x, and

then solve it!

a) Total distance = distance travelled by bike + distance walked

Total distance = 9km + xkm

Total distance = (9+x)km

b)  If the total distance was less than 30 km, the inequality representing this is;

9+x < 30

Subtract 9 from both sides;

9+x-9 < 30-9

x < 21

hence the solution to the inequality is x< 21

The sum of 2 times a number and 8 is 7

Answers

Answer:

The number is -1/2

Step-by-step explanation:

Let x be the number

2x+8 = 7

Subtract 8 from each side

2x+8-8 = 7-8

2x = -1

Divide each side by 2

2x/2 =-1/2

x = -1/2

The number is -1/2

Answer:

2x + 8 = 7

x = -1/2

Step-by-step explanation:

"a number" can be signified by a variable.

So 2 times a number would give you 2x

And 8 would mean to add 8.

Is 7 means the end result is 7.

So 2x + 8 = 7

x = -1/2

A field goal kicker makes 84% of the field goals he attempts he has attempted 50 field goals this season how many goals hs he made

Answers

Answer:

He has made 42 field goals this season

Step-by-step explanation:

To find x% of number y, multiply y by [tex]\frac{x}{100}[/tex] ⇒ [tex]\frac{x}{100}[/tex] × y

∵  A field goal kicker makes 84% of the field goals he attempts

→ That means he makes 84% of his total attempts

∵ He has attempted 50 field goals this season

→ That means his total attempts is 50 field goals

∴ He makes 84% of 50 field goals

84% = 84 ÷ 100 = 0.84

∴ He makes 0.84 of 50

∵ He makes = 0.84 × 50

∴ He makes = 42 field goals

He has made 42 field goals this season

The data below shows the points scored and minutes played by six basketball players during the 2004-2005 season. The least squares regression line for the data is y=.79x+1544

Answers

We assume data and prediction as question is incomplete

Answer and Step-by-step explanation:

Least squares regression line equations are used to model the relationship that exists between two variables, dependent and independent variables. The equation has the form y=a+bx where y is the dependent variable and x is independent variable, a is a constant and is the y intercept and b is the slope of the line. This relationship is then used to predict future outcomes.

Given that data for 2004-2005 for the basketball players are :

James- 20 points

John- 30 points

Chris- 50 points

Dave-15 points

Donaldson- 32 points

Richard -40 points

We predict the scores/points for James (for example) for the following year using the equation of the regression line y=0.79x+1544

We substitute his points x=20 I'm the equation:

Y=0.79*20+1544

=1599.8

The predicted value is 1599.8

The formula h=30+40t-5t^2 can be used to find the height h, in meters, of an object shot upward from the top of a building 30 m above the ground at the initial speed of 40 mps, after t seconds. How much higher above the ground is the object after 4 seconds than 2?

Answers

Answer:

20m

Step-by-step explanation:

Given the formula that modelled the height given as;

h=30+40t-5t^2

At t = 4s

h=30+40(4)-5(4)^2

h = 30+160-80

h = 160-60

h = 110m

At t = 2s

h=30+40(2)-5(2)^2

h=30+80-20

h = 110-20

h= 90m

Difference in height = 110-90 = 20m

Hence the height is 20m higher above the ground at 4s than at 2s
