A triangular pyramid has a base area of 24 square meter and heigh of 4 meters. what is the volume
Answer:
96 meters
Step-by-step explanation:
Volume means length x width x height and since it has already found the length and width, you multiply that by 4. So, 24 x 4 = 96

What are the x- and y-intercepts for the graph of the equation y = 4 - 2x?
Select one:
X-intercept = 2; y-intercept = 4
x-intercept = -2; y-intercept = 4
x-intercept = 4; y-intercept = -2
X-intercept = 4; y-intercept = 2
Answer:
X intercept is -2
Y intercept is 4
Answer:
The first one, [tex]x[/tex]-intercept [tex]=2[/tex]; [tex]y[/tex]-intercept [tex] = 4[/tex]
Step-by-step explanation:
The [tex]x[/tex]-intercept is where [tex]y=0[/tex], so we can solve for it with the following equation:
[tex]0=4-2x→2x=4→x=2[/tex]
So the answer is the first one, but just to make sure, you can solve for the [tex]y[/tex]-intercept because their [tex]x[/tex]-values always equal to [tex]0[/tex] as well:
[tex]y=4-2(0)→y=4-0→y=4[/tex].

Solve the equation 4(h + 1.5) = -6.
h=
Answer:
h=3 is the answer
Step-by-step explanation:
The required solution to the given equation 4(h + 1.5) = -6 is
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
The equation is given in the question as:
4(h + 1.5) = -6
To solve the equation 4(h + 1.5) = -6, we need to isolate the variable "h". We can do this by performing the following steps:
First, we need to get rid of the parentheses around "h + 1.5". We can do this by multiplying everything inside the parentheses by 4:
4(h + 1.5) = 4h + 6
Next, we need to get rid of the coefficient of 4 in front of "h". We can do this by dividing both sides of the equation by 4:
4h + 6 = -6
h + 1.5 = -1.5
Finally, we can subtract 1.5 from both sides of the equation to isolate the variable "h":
h = -1.5 - 1.5
h = -3
Therefore, the value of "h" that satisfies the equation is -3.

Determine if the expression - 10c3 – c4 + 3c2 is a polynomial or not. If it is a
polynomial, state the type and degree of the polynomial.
Answer:
The expression is a fourth grade trinomial.
Step-by-step explanation:
Mathematically speaking, a polynomial is an equation of the form:
[tex]y = \Sigma_{i = 0}^{n} c_{i}\cdot x^{i}[/tex] (1)
Where:
[tex]y[/tex] - Dependent variable.
[tex]x[/tex] - Independent variable.
[tex]c_{i}[/tex] - i-th Coefficient of the polynomial.
[tex]n[/tex] - Grade of the polynomial
Let [tex]y[/tex] be a fourth-grade polynomial, then the expression must be in the form:
[tex]y = c_{o} + c_{1}\cdot c +c_{2}\cdot c^{2} + c_{3}\cdot c^{3} + c_{4}\cdot c^{4}[/tex] (2)
If we know that [tex]c_{o} = c_{1} = 0[/tex], [tex]c_{2} = 3[/tex], [tex]c_{3} = -10[/tex] and [tex]c_{4} = -1[/tex], then we have the following polynomial:
[tex]y = 3\cdot c^{2}-10\cdot c^{3}-c^{4}[/tex]
By Commutative Property:
[tex]y = -10\cdot c^{3}-c^{4}+3\cdot c^{2}[/tex]
We have a polynomial with three elements.
Therefore, the expression is a fourth grade trinomial.
Following are the calculation on the polynomial equation:
Given:
[tex]-10c^3 - c^4 + 3c^2[/tex]
To find:
degree of the polynomial=?
Solution:
[tex]\to -10c^3 - c^4 + 3c^2[/tex]
In the above given polynomial expression, we use the property of the polynomial expression therefore the degrees of the polynomial is "4".

50 ml of water is poured into a beaker. 50 ml of another liquid is poured into the same beaker. The beaker is left undisturbed for some time. After some time, it is observed that the liquid forms a clear layer on top of water. If the density of water is 1 g/cc, what could be the density of the second liquid?
Answer:
Well if you combined 50 ml to a beaker that already had 50 ml of water in it total you have 100 ml of water. The density of the second liquid would be the same as the first beaker but sense they are combined it would be 2 g/cc.

If function f(x) = 2x2 – 3x + 4, then f(x + 3) is equal to f(x+3)= 2x^2 +9x +13.
Degree of polynomial is two so it will have only two solution
f(a)=0 if x=a
or
f(b)=0 if x=b
so put X=x+3
we will get
2[x+3]^2 - 3[x+3] + 4 = 2x^2 +9x +13
so if f(x+3)= 2x^2 +9x +13
The highest degree of a polynomial's monomials with non-zero coefficients is referred to as the polynomial's degree in mathematics. A term's degree is a non-negative integer and is calculated by adding the exponents of all the variables that occur in it.

Estimate 154 divide 7
Answer:
22
Step-by-step explanation:
The result of 154 divided by 7 will be 22.
What is the rule of division?The rules of the division include easy memory tricks that make division calculations easier by generating patterns you may use to deconstruct both simple and complex situations. The guidelines establish requirements that a number must meet in order to neatly divide into another number. While some division rules only require one or two steps to evaluate a number's divisibility, others require two or three steps. Even though some of these formulas are lengthy, division rules help hasten the process of dividing huge numbers.
Remember to continue using the divide, multiply, subtract, and drop-down method for long division problems until all of the dividend's digits have been divided. The solution to the division puzzle is the quotient.
Since the given problem is not a large division. We can solve it by breaking 154 into two parts
______

Complete the equation of the line whose y intercept is (0,-1) and slope of 4
Answer:
y = 4x - 1
Step-by-step explanation:
y + 1 = 4(x + 0)
y = 4x -1
Answer:
y = 4x - 1
Step-by-step explanation:
All you want to do is put the equation into the form y = mx + b where m is the slope and b is the y-intercept (an example would be y = 2x + 1 which would have 2 is the slope and 1 is the y-intercept)
Since you have:
slope or m = 4
y-intercept or b = -1
The equation would be y = 4x - 1
