What are the zeros of the function
f(x)=x^2-7x−30
Answer:
x = 10 , -3Step-by-step explanation:
x² - 7x - 30 = 0
x² + 3x - 10x - 30 = 0
x ( x + 3 ) - 10 ( x + 3 ) = 0
( x - 10 ) ( x + 3 )
x = 10 , -3
Answer:
-3 and 10
Step-by-step explanation:
[tex]f(x)=x^2-7x-30[/tex]
1) Factor the equation
First, find two factors of -30 which has a sum of -7.
⇒ These two factors are 3 and -10.
Then, write the equation as a product of two binomials.
[tex]f(x)=(x+3)(x-10)[/tex]
2) Find the zeros
The zero product property states that any value, when multiplied by 0 will equal 0. Therefore, in this equation, either x+3 or x-10 must equal 0 for the function to equal 0:
x+3=0
x=-3
or
x-10=0
x=10
Therefore, the zeros of the function are -3 and 10.

Vanna is saving for a trip. The hotel room will be $298.17 for 3 nights, and there will be additional fees. What is her daily cost?
Answer:
The daily cost is $99.39.
Step-by-step explanation:
In order to find the answer with the information provided, you have to divide the price given for 3 nights by the number of nights to determine the price per night which would be her daily cost:
$298.17/3=$99.39
According to this, the answer is that the daily cost is $99.39.
if the force of an object is 100N and the mass is 25Kg, what is the acceleration?
Answer:
4ms-²
Step-by-step explanation:
Applied Force=100N
Mass of the object=25Kg
Let the acceleration be 'a'.
Force=Mass*Acceleration
100=25*a
100/25=a
4=a
Chloe is planning an event and purchasing floral arrangements. At Petals Plus, the arrangements cost $33.05 each, and the store charges $64.00 for delivery of the flowers to the event site. At Blooms, the arrangements cost $26.04 each, and the store charges $105.00 for delivery of the flowers to the event site. How many arrangements should she purchase from Blooms in order to get a better value? A. 6 B. 5 C. 4 D. 1
Answer:
A. 6
Step-by-step explanation:
Petals Plus = 33.05x + 64
Blooms = 26.04x + 105
Equate
33.05x + 64 = 26.04x + 105
33.05x - 26.04x = 105 - 64
7.01x = 41
x = 41 / 7.01
x = 5.85
She should purchase 6 arrangements from Blooms in order to get a better value
Check:
Petals Plus = 33.05x + 64
= 33.05(6) + 64
= 198.3 + 64
= 262.3
Blooms = 26.04x + 105
= 26.04(6) + 105
= 156.25 + 105
= 261.24
Petals Plus = 33.05x + 64
= 33.05(4) + 64
= 132.2 + 64
= 196.2
Blooms = 26.04x + 105
= 26.04(4) + 105
= 104.16 + 105
= 209.16
The graph below shows the solution to which system of inequalities?
Answer:
B: y >= 2
y < x
Step-by-step explanation:
The system of equations is the equations of the two line
The flat line is constant (doesn't increase or decrease) and has a y-intercept at two, so the equation for it is y = 2. Notice the shaded region is above the line, and it is not a dotted line so it is y >= 2.
The second line has a y-intercept at 0 and seems to have a slope of 1, so the equation for it is y = x. Notice the shaded region is below the line, and it is a dotted line so it is y < x.

Identify the center and radius of the circle with the following equation: [tex]x^2+y^2+4x+8y+11=0[/tex]
Hey there,
Put the equation into the circle equation [ (x - h)² + (y - k)² = r² ].
x² + y² + 4x + 8y = -11
(x² + 4x) + (y² + 8y) = -11
(x + 2)² + (y + 4)² = 9
If that is confusing, you can always rewrite it to show exactly what you need in the circle equation.
(x - (-2))² + (y - (-4))² = 3²
Therefore, using the circle equation we can see that the center is at the point (-2, -4) and the radius is 3.
Best of Luck!
Answer:
[tex] \displaystyle \text{centre} :( - 2, - 4)[/tex]
[tex] \text{redius} : 3[/tex]
Step-by-step explanation:
we are given a circle equation
[tex] \rm \displaystyle {x}^{2} + {y}^{2} + 4x + 8y + 11 = 0[/tex]
we want to figure out the centre and the redious of the circle from the equation notice that the given circle equation is in general form given by
[tex] \rm \displaystyle {x}^{2} + {y}^{2} +A x +B y +C = 0[/tex]
general form of circle equation is a simplified version of standard form. the standard form of circle equation is given by:
[tex] \displaystyle (x - h {)}^{2} + (x - k {)}^{2} = {r}^{2} [/tex]
where:
(h,k) is the centrer is the rediousnotice that the there're two completed squares in the standard form therefore we can consider completing square to figure out the centre and the redious
indentifying centre and redious:
rearrange:
[tex] \rm \displaystyle ( {x}^{2} + 4x ) +( {y}^{2} + 8y) + 11 = 0[/tex]
cancel 11 from both sides:
[tex] \rm \displaystyle ( {x}^{2} + 4x ) +( {y}^{2} + 8y) = - 11[/tex]
add 4 to the both sides so that the equality don't affect:
[tex] \rm \displaystyle ( {x}^{2} + 4x + 4) +( {y}^{2} + 8y) = -11 + 4[/tex]
simplify addition:
[tex] \rm \displaystyle ( {x}^{2} + 4x + 4) +( {y}^{2} + 8y) = - 7[/tex]
once again to complete the square add 16 to both sides which yields:
[tex] \rm \displaystyle ( {x}^{2} + 4x + 4) +( {y}^{2} + 8y + 16) = 9[/tex]
complete the squares by using (a+b)²=a²+2ab+b² pattern:
[tex] \rm \displaystyle ( {x}+ 2) ^{2} +( {y} + 4) ^{2} = 9[/tex]
we can still rewrite it to figure out the redious and the centre:
[tex] \rm \displaystyle ( {x} - ( - 2)) ^{2} +( {y} -( - 4) ) ^{2} = {3}^{2} [/tex]
therefore we obtain:
centre:(h,k)=(-2,-4)redious:r=3and we are done!

F(x) = x^2 -7x +14, g(x) = 4x -9
Find (g ° f)(x)
Answer:
Set up the composite result function.
g(F(x)) Evaluate g(x2−7x+14)
by substituting in the value of F into g.
g(x2−7x+14)=4(x2−7x+14)−9
Simplify each term.
g(x2−7x+14)=4x2−28x+56−9
Subtract 9 from 56.
g(x2−7x+14)=4x2−28x+47

In ATUV, the measure of _V=90°, the measure of ZT=66°, and TU = 93 feet. Find
the length of VT to the nearest tenth of a foot.
U
93
660
T
V
X
Answer:
VT = 37.8 ft
Step-by-step explanation:
Here, we want to get the measure of VT
We need the diagram of the triangle here
We can get this in the attachment
From the diagram, we have it that the hypotenuse is the length UT since it faces the right angle
VT does not face the given angle , nor the right angle; this mean VT is the adjacent
Mathematically, the trigonometric ratio that connects the adjacent to the hypotenuse is the cosine
Thus;
cos 66 = VT/UT
cos 66 = VT/93
VT = 93 * cos 66
VT = 37.83
To the nearest tenth of a foot, VT = 37.8 ft
