Answer:

Option A, [tex]z =[/tex] ± [tex]13/5[/tex]

Step-by-step explanation:

Step 1:  Add 140 both sides

[tex]25z^2 - 140 = 29[/tex]

[tex]25z^2 - 140 + 140 = 29 + 140[/tex]

[tex]25z^2 = 169[/tex]

Step 2:  Divide both sides by 25

[tex]\frac{25z^2}{25} = \frac{169}{25}[/tex]

[tex]z^2 = 6.76[/tex]

Step 3:  Square root both sides

[tex]\sqrt{z^2} = \sqrt{6.76}[/tex]

[tex]z =[/tex] ± [tex]2.6[/tex]

[tex]z =[/tex] ± [tex]13/5[/tex]

Answer: Option A, [tex]z =[/tex] ± [tex]13/5[/tex]

Answer:

base(b)=10 and height(h)=6

Step-by-step explanation:

From the question,

base(b)=x feet

height(h)=(x-4) feet

Area(A)=30 square feet

Now,

We know,

Area of triangle(A)=1/2*b*h

or, 30=1/2*x*(x - 4)

or, 30=1/2*x^2 -4x

or, 30*2=x^2 -4x

or, 60=x^2 -4x

or, 0 = x^2 -4x -60

or, 0 = x^2 +6x - 10x -60

or, 0 = x(x + 6) -10(x + 6)

or, 0 = (x+6) (x-10)

Either,

x+6=0. or, x-10=0

or,x= -6. or, x= 10

Since, the base of the triangle can not be negative number then, x≠ -6feet but x=10feet

Lastly,

Height(h)=X - 4

=10 - 4

=6 feet

Answer:

Area = 261

Answer:

20 seconds

Step-by-step explanation:

The time taken by projectile to hit the ground is 20 second.

The polynomial equations of degree 2 for a single variable of type f(x) = ax2 + bx + c = 0, where a, b, c, ∈ R, and a ≠ zero, are known as quadratic equations. The leading coefficient is referred to as "a," and the absolute term of the quadratic equation is referred to as "c." The roots of the quadratic equation (α, β). are the values of x that satisfy the equation.

Given initial velocity of a projectile = 98 m/s

equation h = -4.9t² + 98t

where t = time and h = height of projectile,

time taken by projectile to hit the ground,

where h = 0

equation will be

-4.9t² + 98t = 0

4.9t² = 98t

4.9t = 98

t = 98/4.9

t = 20 second

Hence time taken is 20 second.

Answer:

The probability that exactly 1 of the next 2 meals is overcooked = 3.34%

Step-by-step explanation:

The probability that a meal at a restaurant is overcooked is 10%

The probability that exactly 1 of the next 2 meals is overcooked = out of 3  meals 1 meal is overcooked of 10%

= 1 × 3 × 10%

= 10 × 3 %

= 3.34 %

Answer: [tex]\frac{23}{7}[/tex]

Step-by-step explanation:

    An improper fraction is a fraction with the wholes / ones in the numerator.

3 * 7 = 21

21 + 2 = 23

[tex]\frac{23}{7}[/tex]

Answer:

23/7

Step-by-step explanation:

You multiply 7 times 3 which equals 21 then add 2 and get 23 you leave yor denominator the same.

So you multiply your denominator by your wole number then add the whole number (21) by your numerator (2) and leave your denominator (7) as it is.

Answer: 70%

Step-by-step explanation:

Not sure if this is correct but according to the red numbers there is a total of 20 classes. Looking at how many of these classes have 21 or more students we can see that the last three bars contain classes of 21 or more students. The last three bars contain a total of 14 of the 20 classes.

14/20 = 0.7 = 70%

meaning 70% of the classes contain at least 21 students.

Answer:

  C.  f(x) > g(x) for x > 2

Step-by-step explanation:

Using a graph is probably the easiest way to compare an exponential function with a polynomial function. There are no algebraic methods for finding points of intersection. ("Trial and error," or "table of values" will work.)

A graph of these two functions shows f(x) > g(x) except on the interval [1, 2]. That is, f(x) > g(x) for x > 2.

Answer: 21.5

Step-by-step explanation:

The order of operations are:

1) Parenthesis and Brackets

2) Exponents

3) Multiplication and Division (from left to right)

4) Addition and Subtraction (from left to right)

Parenthesis are first so let's solve them first

43 ÷ (7 − 3) × 2

43 ÷ (4) × 2

Now we only have division and multiplication

So we must do this from left to right, starting by 43 ÷ 4

43 ÷ 4 × 2

10.75× 2

Finally, multiply

10.75× 2

The analysis shows there is a correlation between income and phone usage. There may or may not be causation. Further studies would have to be done to determine this.

Correlation is a statistical measure used to measure the relationship that exists between two variables. It is used to measure the direction of change in one variable when there is a change in another variable.

Causation is when a change in one variable leads to another change in the other variable.

However if you are asking how many different combinations, there can be 5005 different combinations.

Answer:

2 different groups of 6 children.

Step-by-step explanation:

There are 15 children you need to bring. You can fit 6 children in each van.

One van : 6 children

Two vans : 12 children

Three vans : 18 children

If you take two vans, that will take 12 children. But you need to fit 15.

If you take three vans, that will take 18 children. This is more than enough.

15 children - 6 = 9 children

Thats one group with 9 children left to take

9 children - 6 = 3 children

Thats two groups with 3 children left to take

3 children - 6 = -3.

This doesn't work. In this case, there will be 3 more empty seats in the last group.

Since the question asks how many groups of 6 children you can drive. It would be two. Becuase there are 2 groups of 6 and one of 3.
