Answer:

c = 289

Step-by-step explanation:

The discriminant is equal to zero. a = 1, b=34

[tex]b^{2} -4ac=0\\(34)^{2} -4(1)c=0[/tex]

[tex]1156-4c=0[/tex]

[tex]-4c=-1156[/tex]

10p

hope it really helps...!!!

Answer:

10p

Step-by-step explanation:

3 +7 =10

p+p=p

3p+7p=10p

By using properties for exponents, we will see that the equivalent expression is:

[tex]2x^{-4}y^6[/tex]

Here you need to remember the property:

[tex]a^n/a^m = a^{n - m}[/tex]

We have the expression:

[tex]\frac{-4x^{-3}y^4}{-2xy^{-2}}[/tex]

We can separate the fraction to:

[tex]\frac{-4x^{-3}y^4}{-2xy^{-2}} = \frac{-4}{-2}*\frac{x^{-3}}{x} *\frac{y^4}{y^{-2}}[/tex]

Now we can simplify by using the above relation, we will get:

[tex]\frac{-4x^{-3}y^4}{-2xy^{-2}} = \frac{-4}{-2}*\frac{x^{-3}}{x} *\frac{y^4}{y^{-2}} = 2*x^{-3-1}*y^{4 - (2)} = 2*x^{-4}*y^6[/tex]

So the correct option is the last one.

Option D

Step-by-step explanation:

just apply the formula you can find immediately on the internet.

that is much faster than putting such a calculation question in here.

the area of a circle is

pi×r²

with r being the radius.

so, in our case we have

pi × 3² = pi × 9 = 28.27433388... ft²

when using 3.14 for pi we get 28.26 ft²

Answer:

let b = amount of balloons; 10b = 120

Step-by-step explanation:

to do this you should first have a let equation

let b = balloons

then because 10 times the number of balloons is 120 you multiply them

it looks like this

10b = 120

This means that a graph of Kassie speed given by the function d = 1.22t would have a slope of 1.22 m/s.

An equation is an expression that shows the relationship between two or more numbers and variables.

Let d represent the number of meters she swims in t seconds. Hence:

d = 1.22t

This means that a graph of Kassie speed would have a slope of 1.22 m/s.

The best statement that compares the length of time each ball is in the air is seen in the second option.

A quadratic function follows the condition: f(x) = ax² + bx + c. Here (a, b, and c) are real numbers and a ≠ 0.  

From the given information:

Where;

The table given is as follows:

Time (in seconds)                 height, g(t) in feet

0                                             4

1                                              36

2                                              36

3                                              4

From the table, when t = 0, the function becomes:

f(t) = -16t² +64t + 5

f(t) = -16(0)² + 64(0) + 5

f(t) = 5

Therefore, we can conclude that the best statement that compares the ball is: f(t) is in the air for about 5 seconds, and the ball represented by g(t) is in the air for about 3 seconds.

There are 12 inches in every foot and the area will be increased by 144 factors.

We know that the feet and inches are the units of length. One foot is 12 inches.

The length and the breadth are given as 11 feet and 13 feet.

The area of the bedroom is 143 square feet.

We know that 1ft = 12 in

So, The length would become 11 feet to 132 inches.

The breadth would become 13 feet to 156 inches.

The area of the rectangle = length × Width

Therefore, the area of the rectangle = 132 ×  156

Since area of the rectangle= 20592 in .sq

The area of the bedroom increased by 144 factors.
