Function “p” is in the form y=ax^2 + C. If the values of “a” and “c” are both less than 0, which graph could represent “p”?
A. Graph A
B. Graph B
C. Graph C
D. Graph D
Answer:
B
Step-by-step explanation:
Since the value of a is less than 0, the graph of the parabola would be opening downwards. Because of this we can rule out option C. In a quadratic equation, c represents the y-intercept, and, in this case c is negative, meaning the y-intercept is less than 0. Only option B has a downward-opening curve and a y-intercept less than 0, so it is the answer.
Answer:
B. Graph B

Shane uses a hand lens to examine a piece of granite rock. He observes that the granite is made up of very large crystals.
Group of answer choices
minerals
fossils
soils
shells
Answer: Hope This Helps!
Step-by-step explanation:
1: Igneous: Igneous rocks are formed by cooling magma. The location of the formation of the rock, as well as how fast the magma cools will determine the type of igneous rock.
2: Glassy and Metallic: Luster definition; the state or quality of shining by reflecting light; glitter, sparkle, sheen, or gloss: the luster of satin.
3: Minerals: The large mineral crystals in granite are evidence that it cooled slowly from molten rock material.

How many solutions does the equation
-2(x + 3) = 2x - (5 – x) have?
Step-by-step explanation:
-2(x + 3) = 2x - (5 – x)
-2x+6= 2x-5+x
-2x+6=3x-5
-2x-3x=-5-6

What is the average rate of change of f(x) on the interval [-3, -1]?
Answer:
To get a more specific answer, you'll need a specific function formula.
Step-by-step explanation:
The average rate of change in a function is the slope of a segment connecting two points on the graph of the function. If a formula (rule) for the function is given, then a graph is not usually necessary.
Example: Given the function [tex]f(x)=x^2[/tex], what is the average rate of change on the interval [tex][-3,1][/tex]?
Find the value of the function at each endpoint.
[tex]f(-3)=9\\f(-1)=1[/tex]
Then find
[tex]\frac{f(-1)-f(-3))}{-1-(-3)}=\frac{1-9}{-1+3}=\frac{-8}{2}=-4[/tex]
The average rate of change in f on the interval is 4.
i need help with this
Answer:
A
Step-by-step explanation:
For the first block, you need to multiply a x a x b
3 x 3 x 6 = 54
For the 2nd block, you need to multiply a x a x c
3 x 3 x 12 = 108
Now you need to add both volumes of the blocks
108 + 54 = 162 in^3

At Edison Middle School, 54.4% of the
72
students chose chicken tacos as their
favorite school lunch, and 36% chose fish
tacos. There are 750 students in the
school. How many did NOT choose a type
of taco?
PLZ HELPP (7th grade math) ASSAAPPP
Answer:
6.912 students did NOT choose a taco type out of the 72 students.
Step-by-step explanation:
I got the number of kids for 54.4% of 72 and 36%, and added them, then subtracted that from 72 to get the total amount
750 - 750 * 0.544 - 750 * 0.36 = 72.

Jeffrey and Marie just had a baby and want to invest money into a bank account to save money for their newborn. The bank account they are looking into yields 6.8% interest each year. If Jeffrey and Marie invest $500, how much money will be in the account when their child's turns 18 years old
Answer:
$1,112
Step-by-step explanation:
6.8% x 500= 34
34 x 18 = 612
612 + 500 = 1112

Find the median, first quartile, third quartile, and interquartile range of the data.
68, 74, 67, 72, 63, 70, 78, 64, 76
Given:
The data set is:
68, 74, 67, 72, 63, 70, 78, 64, 76
To find:
The median, first quartile, third quartile, and interquartile range of the data.
Solution:
We have,
68, 74, 67, 72, 63, 70, 78, 64, 76
Arrange the given data in ascending order.
63, 64, 67, 68, 70, 72, 74, 76, 78
Now divide the data in two equal parts.
(63, 64, 67, 68), 70, (72, 74, 76, 78)
So, the median of the given data set is 70.
Divide each parenthesis in two equal parts.
(63, 64), (67, 68), 70, (72, 74), (76, 78)
Now, the first quartile is:
[tex]Q_1=\dfrac{64+67}{2}[/tex]
[tex]Q_1=\dfrac{131}{2}[/tex]
[tex]Q_1=65.5[/tex]
The third quartile is:
[tex]Q_3=\dfrac{74+76}{2}[/tex]
[tex]Q_3=\dfrac{150}{2}[/tex]
[tex]Q_3=75[/tex]
The interquartile range (IQR) is the difference between third quartile and first quartile.
[tex]IQR=75-65.5[/tex]
[tex]IQR=9.5[/tex]
Therefore, median is 70, first quartile is 65.5, third quartile is 75 and the interquartile range is 9.5.

What is the domain of the function y = l n (x + 2)
A. x < -2
B. x > -2
C. x < 2
D. x > 2
Answer:
Option B.
Step-by-step explanation:
For a function f(x), the domain is the set of all the possible values of x that can be used in the function.
We know that the natural logarithm is only defined for positive real numbers.
So, the function:
Ln(x + 2)
Works always that
x + 2 > 0
So we can just solve this inequality for x, and that will give us the domain of the function.
To isolate x, we just need to subtract 2 in both sides of the inequality.
x + 2 - 2 > 0 - 2
x > - 2
This is the domain of the function.
The correct option is B.
Answer:
b.x>-2

In the triangle shown above, m∠B = 105°, a = 12 in, and c = 8 in. What is the approximate length of side b?
A.
257.69 in
B.
14.44 in
C.
15.26 in
D.
16.05 in
Answer:
Step-by-step explanation:
Since we have one angle with an opposite side and another side known, we are dealing with an ambiguous case. There are either
0
,
1
or
2
solutions to this triangle.
We start by determining the measure of
A
using the law of Sines, since we already know the measure of side
a
.

A

(

)
A
=

˚
There is only one solution to this triangle, because if it was, then the alternative measure of A would be
180
˚
−
36
˚
=
144
˚
, which when added to
B
, would make the sum of the angles in the triangle exceed
180
˚
.
We can now use the measure of angles
A
and
B
to solve for angle C.
A

B

C
=

36
˚
+
105
˚
+
C
=

C
=

The last step is using this information to reapply the law of sines and determine the length of side
c
.
