Answer:

Step-by-step explanation:

35=-5t²+10t+22

5t²-10t+13=0

disc =b²-4ac=(-10)²-4×5×13=100-260=-160<0

t is imaginary.

So ball never reaches a height of 35 m

it's going to be 5

Step-by-step explanation:

Answer:

f(x + 1) = x² - x

Step-by-step explanation:

f(x) = x² - 3x + 2 when f(x + 1)

f(x + 1) = (x + 1)² - 3(x + 1) + 2

f(x + 1) = (x² + 2x + 1) + (-3x - 3) + 2

f(x + 1) = x² - x + 0

f(x + 1) = x² - x

Answer:

x = 15

Step-by-step explanation:

48/12 = 4

60/4 = 15

Essentially, find the growth rate and divide the larger number by that number, or if you were given the smaller number (15), you would simply need to multiply 15 by 4 to find 60.

8.7 is greater than 8.5 because the 7 is more than the 5 and the number 5 is less. Hope this helps :)

Answer:

The absalute value is $6.25 because $12.50-$6.25=$6.25 and thats how much daniel has in his bank account.

Answer:

$18.75

Step-by-step explanation:

6.25 - negative 12.50 = 18.75

Answer:

Madelyn bought 2 bags of popcorn and 8 pretzels.

Step-by-step explanation:

Madelyn and her children went into a movie theater and she bought $39 worth of bags of popcorn and pretzels. Each bag of popcorn costs $6.50 and each pretzel costs $3.25. She bought 4 times as many pretzels as bags of popcorn. Graphically solve a system of equations in order to determine the number of bags of popcorn, x,x, and the number of pretzels, y,y, that Madelyn bought.

\underline{\text{Variable Definitions:}}

​

x=

\,\,\text{the number of bags of popcorn}

One bag of popcorn costs $6.50, so xx bags of popcorn cost 6.50x.6.50x. One pretzel costs $3.25, so yy pretzels cost 3.25y.3.25y. The total 6.50x+3.25y6.50x+3.25y equals \$39:$39:

6.50x+3.25y=39

6.50x+3.25y=39

Since Madelyn bought 4 times as many pretzels as bags of popcorn, there are more pretzels, so if we multiply 4 by the number of bags of popcorn, we will get the number of pretzels, meaning yy equals 4x.4x.

y=4x

y=4x

the number of bags of popcorn

the number of pretzels

The xx variable represents the number of bags of popcorn and the yy variable represents the number of pretzels. Since the lines intersect at the point \left(2, 8\right)(2,8) we can say:

Madelyn bought 2 bags of popcorn and 8 pretzels.

Answer:

[tex]x > 5[/tex]

Step-by -step explanation:

Solving inequalities is similar to solving equations.

[tex]5x + 10 > 35[/tex]

Subtract 10 from both sides.

[tex]5x > 25[/tex]

Divide by 5 from both sides to isolate the x.

[tex]x > 5[/tex]

Step-by-step explanation:

[tex]5x + 10 > 35 \\ \: 5x > 35 - 10 \\ 5x > 25 \\ x > 5[/tex]

Answer:

b,d,e,g

Step-by-step explanation:

Answer:

y=14x-12

Step-by-step explanation:

in the standard format y=mx+b, m is the slope and b is the y-intercept, so this equation would be y=14x-12 since the slope is 14 and the y-intercept is -12.

Step-by-step explanation:

Answer:

Yes, The correct answer is 50.4 oz

Step-by-step explanation:

Answer:

I'm pretty sure the answer is: 6.7 x 10^-3, 6.7%, 6/9, 0.67.

Step-by-step explanation:

Convert everything into decimal form.

6.7 x 10^-3 = 0.0067

6.7% = 0.067

6/9 = 0.66... (repeating decimal)

0.67 = 0.67 (already a decimal)

Once you have converted your numbers into decimals then you can compare them from least - greatest.

Answer:

Step-by-step explanation:

The distance between two points can be found by using the formula

[tex]d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\[/tex]

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

A(-1,7) and B (11, -1)

The distance between them is

[tex] |AB| = \sqrt{( { - 1 - 11})^{2} + ( {7 + 1})^{2} } \\ = \sqrt{ ({ - 12})^{2} + {8}^{2} } \\ = \sqrt{144 + 64} \: \: \: \: \: \: \: \\ = \sqrt{208} \\ = 4\sqrt{13} \\ =14.42220510...[/tex]

We have the final answer as

Step-by-step explanation:

Answer:

439/13

Step-by-step explanation:

Answer:

Not linear.

Step-by-step explanation:

A linear equation is an equation of a straight line, which means that the degree of a linear equation must be  0  or  1  for each of its variables. In this case, the degree of variable  y  is  1 , the degrees of the variables in the equation violate the linear equation definition, which means that the equation is not a linear equation.

[tex]\frac{7}{2}[/tex]

Step-by-step explanation:

Given a quadratic equation in standard form

ax² + bx + c = 0 ( a ≠ 0 ), then

the product of the roots = [tex]\frac{c}{a}[/tex]

2x² + 4x + 7 = 0 ← is in standard form

with a = 2, c = 7 , thus

product of roots = [tex]\frac{7}{2}[/tex]

Answer:

x=[tex]\frac{-2±\sqrt[i]{10} }{2}[/tex]

Answer:

190/100

Step-by-step explanation:

185/100 is greater than 1, so two of those answers are already out.

185/100= 1.85

-1.08 < 1.85 so no

-35/20 = -1.75

-1.75 < 1.85 so this also no

Then the last one is 190/100 = 1.90

1.90 > 1.85

So 190/100 is the answer

Answer:

The coordinates of the point P is (0,0)

Step-by-step explanation:

Here, we want to find the coordinates of point P which divides the segment MN in the ratio 2 to 1.

Mathematically, what we shall use here is the internal division formula;

The internal division formula is given as follows;

(x,y) = (nx1 + mx2)/(m + n) , (ny1 + my2)/(m + n)

From the question;

x1 = -4

x2 = 2

y1 = 4

y2 = -2

m = 2

n = 1

By substituting, we have;

(1(-4) + 2)2))/(1 + 2) , (1(4) + 2(-2))/(1+2)

= (-4 + 4)/3 , (4-4)/3

= (0,0)
