Which statement about k(x)=-x2-2x+15 is true?
A The zeros are -3 and 5, because k(x)= -(x + 3)(x - 5).
B The zeros are -5 and 3, because k(x)= -(x + 5)(x - 3).
C The zeros are -5 and -3, because k(x)= -(x + 5)(x + 3).
D The zeros are 3 and 5, because k(x)= -(x - 3)(x - 5).
Answer:
A
Step-by-step explanation:
Answer:
The zeros are -3 and 5, because k(x)= -(x + 3)(x - 5).

1.dilate by 3/5 : (20,10)
2.translate (x+5,y-6): (7.8)
3.reflx across th x-axis: (4,7)
4.rotate 270 degrees: (7,9)
Answer:
a) )12,6)
b) (12,2)
c) (4,-7)
d) (9,-7)
Step-by-step explanation:
a) Dilation
When we dilate, we multiply the given scale factor by each of the coordinates
We have this as follows;
(20 * 3/5, 10 * 3/5) = (12, 6)
2. Here, we will add 5 to the x-axis value and subtract 6 from the y-axis value
We have this as;
(7+ 5, 8-6) = (12,2)
3. By reflecting across the x-axis
we have (x,y) changing to (x,-y)
so we have ;
(4,7) becomes (4,-7)
4. Rotation by 270 degrees (7,9)
If clockwise;
(x,y) becomes (y,-x)
so we have
(7,9) becoming (9,-7)

34. A store has a loyalty points program. When you
sign up, you get 15 points. You get 4 points with every
additional purchase at the store. Points can be
redeemed for discounts.
How many points will you have after shopping 30
times?
Answer:
135 points
Step-by-step explanation:
We can solve this easily, 30x4=120+15=135
So, after shopping 30 times you would have 120 points plus the 15 you got when making the account, in total 135 points.

Find m∠ J
Use a calculator. Enter only a number
Answer:
26 degrees.
Step-by-step explanation:
We are given
Side KL length which is 46. (let call that side j).Side JL length which is 93( let call that side k).Angle L=90.We are trying to find angle measure of j.
Since we are given a side opposite of our angle we are trying to find and a side adjacent to the angle we are trying to find we are going to use tan ratio.
[tex] \tan(x) = \frac{opp}{adj} [/tex]
[tex] \tan(x) = \frac{46}{93} [/tex]
since we are trying to find the angle measure apply inverse trig function
[tex] \tan {}^{ - 1} ( \frac{opp}{adj} ) [/tex]
Plug 46 for opp and 93 for adj.
[tex] \tan {}^{ - 1} ( \frac{46}{93} ) [/tex]
which is about 26 degrees.

Multiple choice question.
A)
c−64=17
B)
64−c=17
C)
c+64=17
D)
17+c=64
Answer:
i think its B) because its a subtraction equation
The equation that represents the total number of canned goods in Homeroom 106 on Monday will be 64 - c = 17. Then the correct option is B.
What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The act of converting a specified statement into an expression or equation is known as a sentence-to-equation transformation.

Write an exponential model given the points ( 7, 12 ) and ( 8, 25 ). Round to the nearest hundredth.
Answer:
The exponential model is [tex]y = 0.07\cdot e^{0.73\cdot x}[/tex].
Step-by-step explanation:
The exponential model can be modelled by the following mathematical expression:
[tex]y = A\cdot e^{B\cdot x}[/tex] (1)
Where:
[tex]x[/tex] - Independent variable.
[tex]y[/tex] - Dependent variable.
[tex]A, B[/tex] - Coefficients.
If we know that [tex](x_{1}, y_{1}) = (7,12)[/tex] and [tex](x_{2}, y_{2}) = (8,25)[/tex], then we get the following system of equations:
[tex]A\cdot e^{7\cdot B} = 12[/tex] (2)
[tex]A\cdot e^{8\cdot B} = 25[/tex] (3)
If we divide (3) by (2), we calculate the value of [tex]B[/tex]:
[tex]e^{B}=\frac{25}{12}[/tex]
[tex]B = \ln \frac{25}{12}[/tex]
[tex]B \approx 0.734[/tex]
And by (2), we determine the value of [tex]A[/tex]:
[tex]A = 12\cdot e^{-7\cdot B}[/tex]
[tex]A = 0.0704[/tex]
The exponential model is [tex]y = 0.07\cdot e^{0.73\cdot x}[/tex].

The geometric sequence a_ia i a, start subscript, i, end subscript is defined by the formula: a_1 = -\dfrac13a 1 =− 3 1 a, start subscript, 1, end subscript, equals, minus, start fraction, 1, divided by, 3, end fraction a_i = a_{i - 1} \cdot (-3)a i =a i−1 ⋅(−3)a, start subscript, i, end subscript, equals, a, start subscript, i, minus, 1, end subscript, dot, left parenthesis, minus, 3, right parenthesis Find the sum of the first 757575 terms in the sequence.
The sum of the first 75 terms of the sequence is -5.068*10^34
Given the following geometric sequence
[tex]a_1 = \frac{-1}{3} \\a_i = a_{i-1}*(-3)[/tex]
The sum of the nth term of the GP is expressed as;
[tex]S_n = \frac{a(1-r^n)}{1-r}[/tex]
a = -1/3
n = 75
r = a₂/a₁
a₂ = -3a₁
a₂ = -3(-1/3)
a2 = 1
r = 1/(-1/3)
r = -3
Substitute the given values in the formula;
[tex]S_n = \frac{-1/3(1-3^{75})}{1-(-3)}\\S_{75} = \frac{-1/3(3^{75}-1)}{1+3} \\S_{75} = \frac{-1/3(6.082 \times 10^{35}-1)}{4}\\S_{75} = \frac{-1/3(6.082 \times 10^{35})}{4}\\S_{75} = -0.5068 \times 10^{35}\\S_{75} = -5.068 \times 10^{34}\\[/tex]
